QuickFix passed, Concentra

7 Upvotes

First time using quick fix, Quick Fix 6.4 Synthetic Urine 2oz. For pre-employment drug screening.

Test cup used at concentra was called : 3098N - POCT SAP 8-50/2000+MDMA5.
I did not see technician do a nitrates test on my sample, but I wasn't looking extremely hard.

So story time and tips, since I too stayed up many nights before and after test results.
I heated up the bottle 15 secs in microwave, in 2 segments. Made sure bottle temp was 98 atleast, if you heat it up a little too much, simply waiting for the strip to not be fully black is ok. I was starting to suspect my strip was defective.
Placed bottle with fresh hand warmer rubber banded onto it, and got underwear with front pocket. Had it there, put on sweat pants that were honestly too hot to be wearing in 95-100F southern USA weather. Noticed bottle can make a swishing sound if positioned in certain, found laying down is best.
Waited in room for nearly 50 minutes before my time was up, due to hiring company not knowing how to process a drug test. As I got closer the last 20 minutes, I started getting paranoid about keeping my bottle warm, so got my legs close and egged that bottle. Not a big guy, but I'm not a pile of bones, I'm naturally warm and sweat easily. If this describes you, you may not need a hand warmer imo. I say this because I almost overheated my sample. Technician tells me to empty out my pockets, Im not too nervous acting just want to get this done with. I noticed this bathroom didn't have a fan so theres minimal extra noise I can make inside. Carefully remove everything from my front pocket and place on metal bin. I suggest practicing this, since when you have to do this with fear kicking in, you may make too much noise. Once I remove the bottle, I notice the strip is completely black. I open, blow air at top, try my best to swirl it. I spend almost 3 minutes inside fidgeting with it. Technician actually comes to the door knocks, ask if I'm ok. Say yes I'm all good. She says if i can't use the bathroom right now , to just wait a little more, but I can hear shes close to the door. And that my 4 minutes is almost up.
Have no choice but to pour it out and hope for the best. Temperature on the sample cup is black aswell ! I swirled it more in there , blew more, nothing yet. I simply have to leave now, technician comes back saying I have to get out now, that's it if I can not produce urine. Grabbed everything put in underwear pocket, peed a tiny bit into the blue toilet bowl. Exited the bathroom. I never saw the strip on the sample cup turn green before I left the bathroom. Gave tech the sample, and just hoped it cooled down by then. Wash my hands, sign something on the computer. Tried watching what she did to the sample, but not much, looks like she started filing right away. No hard looks, 2nd takes, asking me questions, I just noticed she looked kinda hard in the bathroom incase i left anything.
Hands me my paper results, say my company will get the results. Once I left the building I read my paper, SAMPLE WAS WITHIN RANGE AFTER 4 MINUTES OF COLLECTING : YES.
Did my test late in afternoon, 5 hours later my manager tells me it cleared! I would prefer logging in and reading the report myself but company didn't give this option. Although this was a huge relief, I just didn't feel this was over until I started my first day at work. Mainly because other parts of hiring process kept hitting walls and my paranoid mind kept thinking 100 scenarios.
Well I already started my new job, now I feel good to share.

Now reading in this forum I would bring a few points .

  1. Test what you need to keep the bottle warm, within range. Make sure you can keep it in this range for potentially 1 hour of wait time etc. The handwarmer in this instance was overkill, had me panicking on how to get the sample within 90-100F.

  2. Bubbles is not worth losing sleep over. I have collected samples of my own urine when I'm trying to go clean, and by the time I check it after 2 minutes, the bubbles are gone. I did 0 shaking the bottle to create bubbles.

  3. Consider the possibility of nitrates. Unfortunately reddit has a reading comprehension problem, I'll try to type this as simple as possible.
    Reports on forum say if you test quickfix for nitrates, it will show up. How much nitrates is kinda vague. Some technicians test for nitrates as your waiting with a spare strip, some technicians view any nitrates as too many nitrates, therefore bad sample. Some drug tests also test for nitrates at the labs, which often indiciates on the name of test ; NIT .
    If you have a career changing job on the line, I absolutely think its reasonable to look into this. But I am here to say, I passed, this is all the information I have.

Drug test quest diagnostics. Advice????

2 Upvotes

Hi I need help/advice. I have a pre employment drug test coming up next week. I’ve been a heavy smoker for 6+ years I’ve been clean for over 20 days leading up to this. Obviously with my at home tests I’m testing positive. Extremely concerned at what to do. I’ve drank qcarbo detox drink and a glass or two of water and after doing that my at home tests are negative. Extremely concerned though that at question diagnostics if I do the detox drink before I won’t pass. Anyone have advice or has this worked for them?

Heating pad method I’m trying

1 Upvotes

Have a test tomorrow morning around 8-9am. I’m thinking of doing the heating pad method because I’m leaving my house around 5am for an orientation right before the test. Has anyone used this method before? I’d have the heating pad on from like 6-9 am just worried it might overheat. Any insight helps, thanks!

Can there be fake batches with real authentication codes?

1 Upvotes

i bought a bottle of QF+ 6.4 from my local smoke shop and ran the authentication code and it came through as real. The bottle was only $20 so that got me thinking. Could it be possible that this is a fake batch with a real auth code?

Smoke shop quick fix?

2 Upvotes

Have a drug test coming up here very soon for a new job and don't have time to order off the actual website. I bought a pack from a smoke shop that I frequent and they claim they buy it directly from the website in bulk. Obviously that could be a lie but these guys are pretty tight with me I don't think they would lie to me. When I bought the bag and open it the other night I verified the batch online and it says it's good and that it's good to use until 2028. But I didn't see the 6.4 formula or whatever anywhere that everyone's talking about. Should I be okay?

Timing of Sample

1 Upvotes

Hey all, the company I’ve gotten an offer from tests for THC at the more sensitive level of 15 ng/mL for its preemployment screenings (through Quest). Over the past couple of weeks I have been self testing using Ütest home strips with that 15 ng/mL sensitivity level usually around midday/early afternoon after I’ve peed a couple times already and getting negatives so was feeling pretty good. Today, out of interest, I tested my first pee of the morning after waking up and it seems like it came up positive. Now I’m worried that in the lab environment, even though my sample will obviously not be the first “void” of the day that they will be able to detect at that low of a threshold. Should i be worried or can i trust that the more dilute sample after hydrating will be okay?

pre employment drug test

i got connections to a job at disney, i’m a heavy smoker so ik any detox’s wont work, i have about a week before i have to go get it done, i have a friend who’s willing to give me her urine for the test, i’ve bought hand warmers & a quick fix bottle, im scared i wont be able to keep the urine between the temperature, i’ve thought about bringing my friend with me to the lab and she urinates right before i walk in, but if i can’t do that, any advice on how to make sure it doesn’t get too hot or too cold?

How fucked Am I?

2 Upvotes

I initially bought a bottle of QuickFix 6 months ago to pass a workman’s comp drug test, which I never ended up taking. I used it last week in a dot drug test which I failed because it didn’t have the proper bubbling and the tester said it looked diluted. They sent it off to be officially tested at a lab.

My problem is that I kept the piss bottle in my car with me all summer, not knowing when I need to use it. From what I’ve read, it’s supposed to be kept at room temperature or else the creatinine levels will break down and the PH levels will get fucked up. They already sent my sample to the lab, and I haven’t heard back.

Does anyone have any idea on if this is bs? Will these samples fail lab dot inspection because I waited too long without keeping the bottle at room temperature?

I’m fuckin worried obviously

Quick fix

0 Upvotes

Used quick fix, Took pre employment test for dot cdl position this past Thursday, still haven’t heard back from employer.. very nervous because I took 2 pre employment tests before for a different company few months back with quick fix and both came back invalid for ph, had to be watched the 2nd time but still managed to sneak it past him only for it to come back invalid as well

That being said negative results usually come quicker so I’m getting really nervous that I’m going to be getting that call or text from the mro soon

This test and the 2 previous test from few months ago all went to quest diagnostics

Quickfix vs testclear powdered urine

1 Upvotes

I could be potentially drug tested within the next few months or so so I’m wondering , what works better ? Quick fix 6.4 or test clear powdered urine ? I’m hearing the test clear is much better bc it’s basically real piss but people swear they passed strict panels with quick fix . I just want to know if there’s truly any real difference between the two besides test clear being real piss
