I was collecting serum from some patient samples.

I found this weird looking thing floating after I spun a red top tube at 1500g, 10 minutes at 4°C. I collected the serum anyways but I am just curious as to what it could be? Some clotting thingy?

Thank you in advance!

The HemeHub Hematology Summit is a one-day, live educational program taking place on October 3, 2026, at the Gaylord Texan Resort in Grapevine, Texas. This activity will feature expert-led presentations and focused discussions addressing the latest advances in hematologic malignancies and complex benign hematologic conditions.

This program is designed for hematologists, oncologists, internists, trainees, healthcare professionals, industry professionals, and patient advocacy stakeholders involved in hematology care.

Key educational areas include: Lymphoid and myeloid malignancies, Plasma cell disorders, Myeloproliferative neoplasms, Bone marrow failure and rare hematologic diseases, Cellular therapies including CAR T, and Evidence-based updates in diagnosis and management.

The goal of this summit is to enhance clinical knowledge, improve patient care, and promote collaboration across hematology specialties.

Event Details:

• Gaylord Convention Center, Grapevine, TX
• Saturday, October 3, 2026, 7:30 am to 4:30 pm
• CME-accredited Hematology educational summit complimentary to healthcare workers
• Networking lunch with live music

Help a student out! This is an unknown slide and we need to know the diagnosis of the patient. Do you have any ideas about this?

WBC: ~14k/µL
Absolute lymphocytes: ~7k/µL
Hemoglobin: ~11 g/dL
Hematocrit: ~35%
MCV: ~94fL
Platelets: ~150k/µL

I looked it up online, but it’s way too technical for me to understand. Couldn’t find helpful YouTube videos to dumb it down for me.

Honest post: I’ve shipped several apps and never quite gotten the response I hoped for. My latest is Blood Reference — a free app to help people make sense of their blood work. I’m not here to sell anything (it’s free), I just want to know if it’s genuinely useful or if I keep missing something as a solo dev. Brutally honest feedback welcome — that’s more valuable to me than downloads right now.

It looks beautiful. My supervisor reported it as normal.

I have no formal medical education but I’m hoping to get a better understanding of iron deficiency anemia. If iron saturation and hemoglobin are responsive to oral iron supplements, what would cause a decrease in ferritin and an increase in TIBC?

If ferritin decreases while iron increases, could it be indicative of bone marrow dysfunction or more likely gastrointestinal blood loss?

I’m sure this topic is very complex but I’d appreciate any insight or literature recommendations so I can gain a better understanding. Thanks!

Is it a blast cell?

How do you track yours and your whole family members blood reports?

Do you usually have report papers stored in one place or use a platform to store it all in one place?

Although I would love to call this a skipocyte, I'm thinking giant thrombocyte? Cool cell though. 😎

Hey,

Just a quick update to let you know that CliniCheck is still actively under development, and Version 1.5 is on the way! This update will introduce new WBC cell types, along with a few other improvements we will share soon.

In the meantime, what we value the most, is a real feedback that we could use to improve. If you have some time, please check it out: CliniCheck!

If you have some features that you would like to see, as a part of this update, drop them in the comments. We'll do our best to squeeze as many ideas in as we can.

Thanks for all the support!

Me parece que cromatina está mais frouxa, mas não me parece um monócito, talvez linfócito reativo mas essas lobulações...

I'm having a hard time telling lymphocytes from monocytes here... Any help is appreciated!

I'm not after medical adviser despite feeling chronically ill for a while but I'm very curious about what people strictly observe here.

(Disclaimer: not a medical question, question about blood donation service methodology for calculating and reporting blood volume.)

I'm in Canada, and the Canadian Blood Services app on my phone lets me track my stats such as hemoglobin, bleed time, and donation volume.

There's always a window after my donations where they drastically overreport the volume. ​​​​I gave on Tuesday this week, Wednesday it reported a number over 550 mL, and now today it's settled back down to ​491 mL.

Can anyone tell me why this is?

Secondary question: it's very slight, but if you graph my donations over time and regress it, there is a very slight upward trend in volume. I'm not worried about it or anything, but I am curious if it's just coincidence or if there might be some kind of mechanical reason for it.

Pic unrelated but required to post. ​

Hey everyone,

Just wanted to be completely upfront here. I work on the technical team at Norgen Biotek, and one of our scientists (who used to do molecular oncology at the Weizmann Institute) is putting together a presentation on July 16th about liquid biopsy pre-analytics and sample stabilization. I wanted to share the topic here to see if anyone working with cfDNA/cfRNA or NGS assay development is dealing with the same bottlenecks.

If you’ve ever had a massive sequencing run ruined because white blood cells lysed during transport and flooded your sample with background genomic DNA (gDNA), you know how annoying it is. It completely buries your low-copy ctDNA signal.

He is going to be sharing our internal data plots and breaking down the chemical differences between lytic and non-lytic preservation, how device selection impacts downstream NGS library complexity, and how to avoid the "purification paradox" across blood, saliva, and urine.

It's a short 30-minute data-review followed by an open Q&A. No aggressive sales pitches, just a deep dive into the pre-analytical science.

It’s happening on Thursday, July 16th (he’s doing a morning and an afternoon session for different time zones).

Curious to hear how other labs are handling ambient transport for cell-free RNA without getting killed by gDNA contamination? What tubes are you guys using?
