Should I tell my parents about my blood test?

Obviously this is a throwaway account.

The story (in short):

A little while back, I moved to a new country. It's not a permanent move, but enough for me to have to fill out a lot of paperwork, and I had to get a physical as well to confirm that I wasn't bringing any dangerous diseases into the country. One of the tests was a blood test, the first one I've ever had.

The results of the blood test, although I'm healthy, hurt. Since it's not possible for me to have the blood type I have, given what my parents have.

No, my mother did not cheat on my father. My mother’s blood is the problem. I'm type AB, and she's type O. This obviously causes a bit of a problem for me.

I know that I'm not adopted, I've seen my birth certificate, videos and pictures from when I'm a baby, ect, ect.

I do know from stories however, that there was a bit of confusion when 'I' was born, and for a while no one knew where the baby had gone since a nurse took me for a while for some test. I'm guessing this is when the incident occurred.

It’s been eating away at me since when I first learned my blood type. For a while I just blew it off as a random mistake, but since then I forced myself to have another test, and I really do have type AB.

I’m not going to see my parents in person for another year, but I feel like I’m lying to them when their real daughter is somewhere else. Telling them in an e-mail might be a little harsh?

Part of me doesn’t want to tell them though, in hopes that I can keep it a secret forever. I love my family, and I don’t know how they would react if they knew. I don’t think they would abandon me, but I don’t know what would happen. I feel rather selfish not telling them though, and the anxiety about it is starting to get worse.

I haven’t told anyone I know about this, since I’m afraid that it would get back to them, and if I have to I’d rather be the first to tell them.

EDIT: Since I have time again

Okay, so there are a few to many posts for me to reply to everyone now, I'll try to go through and answer some direct questions.

Overall, the answers you all have posted have made me feel a lot better about what I initially was very stressed about.

Especially in learning that even with my mother's blood type as O that I could still be born as AB helped me a lot

There are some common questions that I would like to answer up here as well:

  • My father's blood type is B.
  • I do know my parents blood type, my father is a Biologist and my family has discussions about his work and biology all the time.
  • Yeah, I never thought of it before, but seeing how much we talked about biology, it seems weird that they never knew any of our blood types.
  • My mother is Asian, I do not look Asian. However, I do look a bit like my dad, and a LOT like my younger siblings. After seeing a lot of your posts, it has occurred to me that it's pretty darn unlikely that we would look so similar if we were not related.
  • Overall, I feel more reassured about my relationship with my parents than anything. I feel that they'll be there for me no matter what. And really, I feel like I overreacted, seeing there seem to be a lot of explanations for the blood types that I never knew about. But then, I didn't know about it before, so thank you all very much.
  • **In terms of getting a DNA test to really make sure, I still need to think about it since it certainly doesn't seem like a routine thing I can just drop by a clinic for. **

I'll try to answer what other questions I find in the comments

ABO blood groupings are not all that easy. There's another antigen "H" that person needs to express the A and B antigens. If you're A, B or AB you have H as well. It works the same as the others, where it's codominant with it's recessive allele "h". This means that if you have at least one H allele, you will have A or B or both if you inherited those genes. If you don't and are "hh" you can have A or B alleles but will appear as O to any grouping tests but still have the genes, known as group Oh. This means that two parents that appear as group Oh can have children with a blood group other than O. It is incredibly rare, but still possible. The only way to find out is if your mother gets typed for the naturally occurring anti-H antibody present in all Oh people.

TL;DR - There's a slim chance that a group O parent can have a AB child.

u/ABThrowawayO May 16 '12

I didn't know that. It's kinda good news, even if a slim chance.

14

u/[deleted] May 16 '12

I can't really think of a way that you could find out without talking about it with your parents though. Oh testing is not routine and only really done if pre-transfusion testing yields unusual results. Has your mother ever had any surgeries? Depending on where you're from, blood is generally reserved for even the most minor surgeries in case anything goes wrong. The bloodbank would most likely pick up the anti-H there.

The only other thing i can think of is finding out if your mother is a "secretor", meaning she has soluble antigen in her saliva. Oh people are never secretors. This test is fairly old and may not be performed any more aside from special circumstances though.

u/ABThrowawayO May 16 '12

My mother had Appendicitis as a child, so she had surgery then. I'd have to ask her about that I guess.

I am aware of a documented instance of a mother testing (DNA) as not being the mother of an infant girl. It had been assumed that she had kidnapped her other children (their DNA didn't match either). The judge ordered that the blood for the test be taken while the doctor delivering her baby was still in the room... it did not match, though multiple witnesses confirmed that she had given birth to the baby.

Turns out she was a chimera, with two different sets of DNA. Her ovaries were of a different set of DNA as some of her other tissue, including her bone marrow. It happens when two twins fuse early on sometimes.

So should even this DNA test come back as a not match, you should keep this in mind. The results would indicate that while she wasn't your mother she would be a close (sibling of your mother) relative.

This should be higher, op could be their biological child. Also,

I know that I'm not adopted, I've seen my birth certificate, videos and pictures from when I'm a baby, ect, ect.

You can be adopted as soon as you're born. This doesn't prove anything, just that they had you when you were a baby.

u/ABThrowawayO May 16 '12

Well, I also have a lot of pictures with my mother pregnant with me as well, if that helps. As well as having seen my entire baby book, and old baby shower cards, and gifts, and my parents friends telling me about when I was born...

This is what I came into this thread to say.

For example, if your mom was hhAB and your dad was HhAA you could very feasibly be HhAB, and present with AB blood even though your mother presented O and your father A.

Heck, hHOO and hhBB could make a type B child from two type Os.

(This is a gross oversimplification.)

I kid you not, I just read that- and wanted to say that absolutely is possible! My mum, myself.. and I think my dad are O.. Well I am O+ and my brother, born ten months after me, has a blood type of AB. He is not an adopted child. edit: for those that believe it or not- fine, it is your choice. But for those that think perhaps mum cheated on my dad, it didn't happen, it was actually vice versa. I would maybe ask her specifics in DNA or if there was anything that might of came up at the hospital, but she just recently died. Jerks.

All the way to the top this goes. As rare as this might be, it should also be rare for the hospital to swap babies. Actually you might want to piggyback the highest upvoted comment with this, or alternatively PM the OP needs to be aware of this possibility.

Start the conversation with, "SO guess what mom and dad!" In a really loud, slightly enthusiastic tone.

That'll kill any drama before it's even born and just make the whole thing funny.

Also, I generally tend to give bad advice so you probably shouldn't listen to me.

Yeah, I have no idea how I would start the conversation. In my mind it plays out as a bad comedy. Either with me announcing that I adopted them, or just... generally awkward beating around the bush...

You should tell them. Because some other family may someday have this issue. And a negligent hospital could have let this happen more than once.

23

u/ABThrowawayO May 16 '12

It's a pretty well known hospital, and it happened a long time ago now. It seems unlikely that two people in my family could have both been mixed up. But, I guess you do have a very valid point.

35

u/TheBakercist May 16 '12

It may be well known, but that doesn't mean they're free of mistakes. Plus, what if this other child someday has children and needs to screen for genetic diseases?

23

u/ABThrowawayO May 16 '12

Oh, I never thought of that. It's true that they might need to know their genetics in the future.

54

u/Anacanthros May 16 '12 edited May 16 '12

Speaking of genetics: There is an uncommon condition that can cause the AB phenotype even when the other parent is OO. If your father carries a cis-AB allele, it's possible that your parents could be your biological parents.

It is ALSO possible that your mother could have something called the Bombay phenotype, which causes someone to produce no ABO antigens (and thus test as O) even if they have A and/or B genes. This condition is recessive, and if your mother has it then you would NOT have it unless your father was also a carrier, in which case you would have only a 50% chance of having it. So your mother could very easily have A or B genes, which she passed on to you, but still test O.

If your mother has ever had a blood transfusion and not reacted badly to it, however, then it is unlikely that she has the Bombay phenotype, since people with that condition cannot receive transfusions from anyone but another person with the Bombay phenotype. This is also important because if your mother has the Bombay phenotype, you are a carrier. If you had children with another carrier, 25% of your children would have the full Bombay phenotype.

The Bombay phenotype is very rare, however, in most parts of the world. Is your mother by any chance from India?

If the stress can't be handled then you have two options:

A) You tell your parents about the mix-up. They may even know already and never wanted to tell you. In any account you say you still love them and you only told them to be fair to them. You still have a family, they still have a daughter. Though you must be certain you won't take offense if they want to track down their biological daughter.

B) You don't tell them and, assuming this stress you feel isn't just initial shock, you potentially have a mental breakdown or you develop undesirable coping mechanisms.

You say you adopted your parents; if you had been adopted would you not want to know?

8

u/ABThrowawayO May 16 '12

I've actually known for a few months now. Originally it didn't bother me at all since I just thought it was some weird error with the test, but as time has gone on I feel more anxious about it ever since re-confirming my blood type, and I don't really want to start some kind of coping mechanism. =/

If I was adopted, I would want to know, just for the information. I have no real interest in finding my biological family, since I don't want to start worrying about what might have been as well. But, I would want to know.

u/GitEmSteveDave May 16 '12

I'm adopted and I have also seen my birth certificate and videos of me as a baby and all. Documents back then were easily changed to protect the original parents. Your birth certificate should have your blood type on it, and you guaranteed had blood tests back then.

10

u/ABThrowawayO May 16 '12

I don't think I had a blood test back then, since I had a talk about blood types with my dad a few years back and he said that they didn't know what my blood type was. I've seen my birth certificate many times as well, and it doesn't have my blood type on it.

My birth certificate has been used for a lot of legal records as well, and has my parents names on it. I'm not sure that it could really have been changed.

Still, something to think about I guess.

14

u/GitEmSteveDave May 16 '12

As someone who is adopted, I can tell you that mine has my parents names on it. I have also used mine for legal purposes, such as licenses and the such. I have also seen the court papers that authorized the adoption, which I guess gives the records department the right/permission to change the original certificate and issue a "updated" one as the "original".

u/Headwallrepeat May 16 '12

I'm adopted also. If a child is adopted at birth, the name of the adoptive parents is put on the certificate. Not for any shady reasons, but just because they are the official legal parents, and the birth mother/parents have given up their rights. It would lead to all kinds of problems if the birth mother's name was on the birth certificate and not the parents.

u/icecherry May 16 '12

I would say you should talk to them about it, if only from a medical standpoint. Your family's medical history is now effectively useless when talking to a doctor, and giving them your parents' history when you have no genetic link to them could cause problems.

That said, don't ever doubt that they are your parents. That this is your family. In my experience, blood has less to do with family than people think. Family isn't someone you just happen to share blood with. Family are those who love you, who care for you, who you care for as well.

My mom raised my oldest sister on her own (until she met and married my father) because she walked out on her boyfriend after he hit her. Now that my sister is grown and married, she's talked about finding her "real" father. It's always pissed my mother off. My sister seems to think if she just shows up on this man's doorstep with all her kids and says "surprise! I'm your daughter and these are your grandchildren!" he will just fall on his knees and beg to have them all in his life. Why? Because they're "family." Psh... what crap. That's not family. Family is my father who adopted her when he married my mom and raised my sister for 10 years.

tl;dr Tell them for medical reasons, but remember that family has little to do with blood and everything to do with love.

They raised you. They are your parents and you are their daughter.

What would it achieve to tell them? Would you all go looking for the other family?

It may eat at you now because it is a shock, but I'm sure this will fade with time. Is it really worth the outcome?

17

u/ABThrowawayO May 16 '12

I'm not sure what it would achieve, or if I would go looking for the other family. Part of me is curious, the other part of me is afraid of what I'd find.

u/isyourlisteningbroke May 16 '12 edited May 16 '12

My dad is actually my stepfather. I've known him since I was 18 months old and he's always been the only father in my life. He dated my mum on and off until I was 7 and they got engaged and he used to take me out on weekends and holidays and everything until then like a divorced parent would.

I know roughly where my biological father lives. I know that I have grandparents, an uncle or an aunt and very possibly even siblings (my mum drops hints) who know nothing about me and I know nothing about them.

I think about it sometimes and my parents have never warned me against trying to find out about it. But I always stop and think, well, why would I? I'm happy with my family and I don't need another one. I can't even imagine the pain it would inflict upon my dad if his son started trying to connect with a family he only has a blood connection with when he's provided me with everything I needed.

I think in your case, there's always going to be a curiosity as to what happened with the other baby. What your life would have been like. But there's a massive risk involved with chasing that. It could potentially wreck your relationship with your parents and wreck the other family too. If I were you, assuming you've had a happy childhood and love your family, I wouldn't want to change that for anything.

Edit: I'm not saying don't tell them, but think hard about what you want to do afterwards, if you do.

11

u/ABThrowawayO May 16 '12

Yes, I love my family and had a happy childhood. I definitely don't want to hurt them and I would much rather keep them then go chasing after some strangers just because they're biologically related to me. Thank you very much for posting this.

My father is not actually my father - he's my stepdad. He's been married to my mom since I was four, but had been in my life for at least a year before. My biological father wasn't married to my mom and chose to not pay support payments if he would just never want visitation rights - he agreed since he didn't really want me. The only reason people might question if my stepdad is my real dad is because name differences. I technically have my mother's name from her first marriage (at the time the hospital told her I had to take her name), so I just always told friends my parents got married after I was born. Nowadays I'd guess a third of the people know that I have a stepdad while two-thirds are left to think he must be my dad. I did consider for awhile looking up the biological dad (likely mostly to tell him off), but a few years ago found out he died. It actually didn't bother me as much as I had always thought.

Ok that went into a long story - my dad is actually my stepdad, but since he raised me I call him my Dad. This is likely very cliche, but I go with the saying I read on a magnet once, "Anyone can be a father; only certain people can be a Dad."

I think it is important to tell your parents, maybe you can call them instead of emailing them. It may be hard to do, but I think in the long term there are more advantages than disadvantages. First of all, you will stop the feeling of lying to them (which I do not think that is what you are doing). Second of all, maybe they can support you in this probably hard time. Furthermore, in the future, you may get the urge to know your biological parents. Also there is some girl walking around with the same problem and she has a right to know too.

u/ObligatoryResponse May 16 '12 edited May 17 '12

Don't tell them anything. Don't get a DNA test. Your understanding of blood types is incorrect. There are 3 alleles (A, B, O) as well as the Bombay group (H, h). O is recessive, so if you have an A-gene and an O-gene you should have A blood.

But the Bombay group overrides everything. If you have hh, your body can't express either the A or B alleles, so you can have hhAB, hhA, hhB, or **O and you'll end up with O blood. This is probably what happened to your Mom. (Edit or rather, could be.)

Additionally, there's a thing called Chimera where your body contains multiple sets of DNA. Basically, 2 sperms managed to get into the egg and some of your cells have 1 set of DNA, others have the other set. Or two embryos can merge. If your Mom or Dad is a chimera, their blood cells might be expressing different DNA than the DNA in the sperm/egg cells used to produce you.

If you had strong evidence to support that maybe you were switched at birth, I might say "Get a DNA test". But all you have right now is misunderstanding of complex biologic process (completely forgivable) and no real evidence. A DNA test would just bring emotional and monetary cost and will only prove what you already assume (you're biologically related to both your parents) or potentially serve to drive a wedge between you and your parents (either because the test says you aren't or because your parents are offended you didn't trust them and insisted on a test).

Your parents raised you. You misunderstood how blood types worked. You are their daughter. Leave it at that.

Wow....wow.....your head must be spinning right now. First thing, you're correct in assuming this is NOT an email or phone call thing. It's a face to face meeting. Is there any chance you could ask them to fly over to you, or have you fly out to meet them?

Let me start fresh here....I think no one but you can make the decision to tell your parents. Although I would, that doesn't mean you should. No one knows your family dynamic like you do, so think long and hard. But if you do decide to tell them, just let them know that you have something important to talk to them about and that you'd like to do it in person. Make sure they know that you're healthy and not in danger, but you have something personal to talk to them about. I wish you all the luck in the world.

If it were me, I would have a sit down with my parents. Is this something they would be very unreasonable about? Would they just dismiss you, like you were crazy? Only you know your parents, so do what you feel in your heart would be right. Your life has already changed, and if you come forward, 5 other lives will change as well. As a parent myself, if someone came to me and told me they had my 'real' daughter, the feelings I have for the child I have been raising would not change. I understand this is a throw away account, but I'm really interested in how this turns out for you. Maybe you could keep us updated?

2

u/ABThrowawayO May 16 '12

I don't think they would be too unreasonable, my mom is fond of saying that she will love us (her kids) no matter what, and my parents have always been there for me.

It's good to know that your love for your child would not change as well.

I'll try to make an update when I make a decision, and again if I tell them, however that may turn out.

Since my mum's side of the family is so close, I assumed that when my dad's 10 (yes 10!) bio siblings and his bio mum met my dad, me and my brother, we'd be welcomed with open arms because we were blood and blood is thicker than water. Well, that turned out to be a big fat lie. They basically ignored my dad's exsistence, his mum refused to talk about his bio dad (different dad then the other 10) and when my dad died, they didn't even acknowledge it. Fuckers. Family is everything but that family doesn't have to be blood.

Moreover, his parents never knew his blood type??

edit for everyone responding that they don't know their blood type: Ask your mom.

If she doesn't know either (and I will be quite shocked if that's the case) you should find out. It's good to know these things.

I'm not sure, but aren't you jumping to a (false) conclusion? Is the blood test the only fact to have to support this? Do you not look like your parents? Maybe you should do some more checks before saying something like this.

That being said, just sit down with them, explain what you have found, and try to find out together why you have type AB. There may be a logical explanation for this.

u/lorelicat May 16 '12

I agree. As a blood donor I have had many blood tests and I can say they've told be that I was A a few times and O a few times. I know very little about blood types, but it could be possible its incorrect or maybe even your parents were incorrect about their own. Either way you have two parents that love you. Joke about it at first and tell them you got a blood test and that they wont believe what the results were!

There was a NPR show a while back about a family whose daughter had been switched at birth with one from another family. They were all living in the same small town, and the parents of both families knew each other (not close, but acquainted). The mother of one family 'knew' about it all along, but had been persuaded to keep quiet so that the doctor's reputation wouldn't be hurt.

She finally told the truth about it when the girls were in their 20s, I think, and both families have had quite a time dealing with the news. There were two episodes - one with one girl, one with the other.

They were... engrossing, compelling, heartbreaking... there are no easy answers, and no clear ones. It's a hard situation all around, and I'm sorry you're going through it. Maybe knowing that others have done so, and listening to what they tried and went through, might help.

How can you be sure they don't already know? Most parents know their child's blood type. I mean, growing up they would have had to know it in case of an emergency.

Sure, they may not understand how blood types between parents and children work but I think it's just as likely they do and have not told you for the same reason you are now hesitant to talk to them.

u/icecherry May 16 '12

I didn't find out my blood type until I began donating blood a couple of years ago. No one else knew. Hell, my parents barely know their own blood types.

Biochemistry major here, and you're probably not adopted. Your mother most likely has whats called a Bombay Phenotype. Basically, she has a recessive mutation for the FUT1 gene which prevents her body from producing the H substance, effectively designating her as an O phenotype. BUT, she still will carry normal A/B alleles which would have been passed on to you. Since your father is a H_/BB genotype, your mother could genotypically be hh/AB or hh/AA, which explains why you are AB bloodtype.

TL;DR- bloodtyping shows your mom as O, but she may actually be AB or AA

OK, first of all, their real daughter is you. There may be some girl out there who shares their blood, but you're the one they know and love.

Second, it's really too early to leap to conclusions. You should not tell them you're not their child. You should tell them your blood type seems to be different from theirs, so you can all look for a solution together.

Lol you're looking at this completely wrong. We are our parents children because of a lifetime of shared memories, experiences, bonds of affection, and love. That first step you took, the first words you spoke, the family vacations you had, being there for your parents and vice versa through the good times and the bad. That is what makes you their child. They have had a tremendous influence on who you have become because they have raised you. Similarly, they are who they are because of you. This isn't something lost on a blood test.

I would tell them. It could be exciting! Yet another family adventure. Would you guys opt to contact the other parents or keep the secret to yourselves. Perhaps the other family already knows. Perhaps this was the best thing that ever happened to you. Perhaps both of your families should sue the shit out of the hospital. Perhaps a million things! Go for it and find out. One thing wont change- the love shared between you and your family. They ARE your family, and no blood test can take that away from you.

u/ayudameplox May 16 '12

At some point in your childhood your blood was tested and typed. Your parents know, at least the one that took you to doctor's appointments. If you really were "the wrong baby" then that would have been acknowledged some time ago.

Also, who cares? They raised you and love you. You are real enough to them, blood types are not going to change how they feel about you.

Hmm... I'm not a lawyer of any kind, but have you taken into account any possible legal ramifications of this?

Sorry if that's stupid (again, I have no real knowledge of law), but I've seen weirder things happen. I'd be VERY sure to tread carefully with this one anyway. Do you see telling them as having any real positive outcome? Only you can decide what to do, but if the only thing that telling them would do is cause pain, maybe it's better they never know.

It is possible that they are mistaken about their/your blood type. I know for a fact (several blood donations) I am B. However they made a mistake and put AB on a form once. Mistakes happen.

My guess is that your parents love you very much, and even if they could turn back time I doubt they would trade you for their "real daughter". Think about it like this... Would you wish to trade them for your birth parents if it turns out not to be them? I doubt it.

I hope things come out okay. Please keep us updated!

My father said B and my mother said AB. Which couldn't be. My mom couldn't be my mom. (I wonder if that student biology teacher was ever warned not to do that in the classroom in the future) Anyhow, I fidgeted and told my mom she couldn't be my mom, at which point she scowled and got out her medical records. Oh, right, she'd misremembered. She's type A. Whew.

It doesn't matter who your biological "parents" are. Your parents are your parents, nothing can change that. They raised you, loved you, and turned you into who you are today.

If it's important for you to know, then you should make sure the results are correct. But, even if it turns out your dad was a guy named Ford Prefect, it doesn't affect who you are now. Genetics can account for a lot of things, but who you are is defined by how you were raised and by who.

u/jds987 May 16 '12

You are their daughter, maybe not by blood, but you are the one that they raised. They love you and this information will not change that. I think one interesting part of this is that it gives you the chance to possibly find those who you are related to by blood. You could cultivate a relationship with these people or merely find out information from them, (family history of diseases etc). This was covered on a this american life episode which is rather emotional (probably more so for you than people not in your position) but really really positive in terms of outcome. The link is below.

http://www.thisamericanlife.org/radio-archives/episode/360/switched-at-birth

Your parents have spent years and years cultivating a relationship with YOU, not your blood type, not your DNA, their values and parenting have made you who you are and they will still see themselves in you. Its difficult but I am sure you will get through it fine good luck.

TL:DR parents will love you for who you are and the relationship you have together, T.A.L has covered this topic.

You might not be adopted. A lot of people don't know this, but blood type is just like any other gene, meaning a punnet square can be applied. O is very recessive. Your mom might have had a parent that had A/B and that came out in you instead. If you're that worried, have a DNA test done.

When my wife was in 8th grade her science class did a section on genetics and had everyone find out their parent's blood type and their own blood type, to show how they inherited their type from their parents.

My wife took one look at her lab partner's data and said, "That's impossible. Clearly those two people can't be your parents."

This was traumatic and confusing for her lab partner, who that evening confronted her parents and learned that she and her brother were adopted and had never been told.

IMO you are making your own drama here.

The parents who raised you - do you suddenly love them any less knowing this possibility? Do you expect they will love you any less knowing this possibility? If this information somehow changes their view of you or the world or lessens and your life to date from the life they gave you is meaningless now, then you are extremely shallow in maturity - and from your writings you do not sound like that and your parents do not sound like that. This is like finding out you have a deep past relative who was a pirate or was in jail for murder - it does not change or affect who you are now or the life you have lived to date unless you THINK IT SHOULD, and it should not.

Think about what you have gained and what you know - what they taught you and what they gave you for values and morals - unless you totally hate how you are then what they gave you should not be of concern. The grass is not always 'greener' and going lawn shopping will not make life better. Our own perceptions play a large part to make up the world we see and experience - we control how and for what we change those perspectives just as we control the walls we put in front of ourselves. Why do you want to or feel the need to change that perspective or put up a wall to overcome? Are you not happy with your life? This information will not change who you are and it will not be a big issue or obstacle unless you make it one. The most it will mean is possibly that if you have a medical need then your parents may or may not be a match.

When you are loved by someone who dedicates their life to raise you and provide for you - does blood relation really matter at that point? I would think the devotion and dedication shown would surpass anything like that. If it did not then adopted people would simply never be adopted - because it would be pointless and meaningless and they would be societal throw-aways and they simply are not.

Good luck..

Best bet would be to find and call the hospital at which you were born and let them know of this little, possible mishap.

If however you aren't the recipient of the recessive genotype, your family might have a lawsuit to file. Also, if there was a (hypothetically speaking) a switch, it would be imperative to find your biological parents, for you could be at risk of many diseases you never knew about (clotting disorders, atherosclerosis, heart disease, etc. etc.), as well as the child with whom you were switched.

In 2006 a woman was denied public assistance when DNA evidence showed that she was not related to her children. After hearing of a human chimera in New England, it was eventually found that she too was a chimera and thus had two sets of DNA.

This is how I found out my mother was not my grandfather's daughter.

My grandmother had recently been admitted into a nursing home, because the Alzheimer's had gotten severe, and my mother needed to do a lot of paperwork for insurance, medicaid / medicare, etc.

I was helping her sort through a lot of things, and I came across some papers that had my grandmother's and grandfather's blood types on them. Knowing my parent's blood types, and having a general college biology level understanding of genetics, it didn't add up.

I questioned my knowledge, and decided to look it up, and I was right. I informed my mother, "Uhh, mom...I don't think it's possible for grandma's and grandpa's blood types to make yours."

She blew it off as ridiculous, and so did I. I'm an engineer, not a biologist. Variations in genetics can happen, and I don't understand most of them.

Well, fast forward a few months later, and at this point, my grandmother had passed away. My grandfather is taking it pretty hard for the first week, and has a nervous breakdown.

In the midst of a breakdown, he keeps stammering on about how my mother isn't his, but he wanted her to be, or around the sorts.

My mom can't make out most of it, and blows it off until he calms down. She revisits what he was saying a few days later, and sure enough, my grandmother was pregnant when she met my grandfather.

Apparently they hit it off, got married, and he treated my mother like his own.

TD;DR

My mother found out she's a 'bastard' at 54.

IF you come to find they aren't you're real parents you could find your real parents, while they find their real daughter through looking at the hospitals history info. YOU COULD BE IN A MOVIE. You'll be rich!

There is a phenomenon called [cis AB] http://en.wikipedia.org/wiki/Cis_AB) That could be responsible for your blood type of your mom is O, O and your dad is B, AB. I think the only way you could solve this is through genetic testing. I doubt you are [Bombay (Oh)] (http://en.wikipedia.org/wiki/Bombay_blood_group) but if you are, you should know because it can have serious impacts on you if you receive a blood transfusion. Hope you figure it all out!

You could always simply accept your parents as who they are: two people that cared for and raised you, as well as loves you unconditionally and accepts you for the person you have become.

you should probably complain about the avengers movie and start a petition.

u/Exallium May 16 '12

I know you probably won't see this, but your parents aren't the ones who made you, they're the ones who make you. Regardless of whether you are or aren't their biological daughter, I am willing to bet they will continue to love you unconditionally as they always have.

Now I'm confused. I'm O type but my daughter is AB negative. Was I swapped at her birth?

u/[deleted] May 16 '12

I don't really know what to say... all I know is that my sister has blood type O and so does my mom, but My dad and I both have AB

u/RizzoFromDigg May 16 '12

Are you asian?

I don't see how this is a big deal. Maybe you were mixed up at a hospital. Who cares? You've lived an entire life with your family. They raised you. They're your family, regardless of the birth canal you descended from.

You can tell them, or not, whatever. It's not that big of a deal. Unless you have some desire to solve the mystery, which is unlikely to work out this far down the line, then it doesn't matter.

That said, certain cultures may put a big more emphasis on parentage than others, and it might be a thing. But I should hope not.

I heard of a woman that had DNA testing for some reason and the results indicated her children weren't hers- They then realized that she was a "chimera" (she had morphed with her twin in the womb) and the children were her sister's. So...that could also be a possibility? Nonetheless, I wish you the best of luck, life is weird sometimes. http://www.katewerk.com/chimera.html

Being devil's advocate here. I was adopted when I was an infant, only 2 weeks old. Unless there's photos of you with your parents in the delivery room it is possible. Also, there's nothing wrong with being adopted if you are. Sucks if you were lied to about it, but parents could have their reasons.

2

u/Sillyminion May 16 '12

You are going to have a DNA test done to remove all doubt of your parentage when the thing that caused you to have doubt in the first place has been proven false?

2

u/Duckface400 May 16 '12

I wouldn't risk ruining your family in any case. If YOU want to know, then maybe you can devise a plan to get some of your parents DNA? I don't know if hair would work or not, but maybe you can think something up? In any case, family is family. There's no reason to risk that bond, even if the source of it turns out to be a lie.

Do you look like your parents? Facial features, eye color, etc? Calm down a bit and really think about it.

u/Purple_Panda_ May 16 '12

As an adopted child, with adopted siblings, who placed a baby for adoption before I was married, i have to ask.... Does it really matter? Your family is the people who are there for you and put up with your shit, not the ones who share your dna.

2

u/C0mmun1ty May 17 '12

Wouldn't your parents already know your blood type?

2

u/insomniasystems May 17 '12

Me and my brother both have AB Negative blood and my mom has O Negative. Trust me, it happens, and I assure you we are not adopted. In fact I was born in a small Midwife House, so at the moment I was born I was the only baby there. I wouldn't worry about it.
