Blood clots while entering test tube

I've been here for my husband's APS (he also has polycythemia), but now I have a question for myself. On Oct 27th, I fainted & ended up in the ER. Blood tests were done, but after 15 - 30 minutes, the lab had to get all new blood because my blood had clotted in the tubes. On Oct 27th, I went back to the ER because of still having problems with fainting & I was an having extremely bad, non-stop headache. A lab tech went to draw blood, but it clotted in in the first tube almost immediately. When the needle was pulled out, I didn't bleed at all. She drew blood from another spot & I guess it was okay.

My question is, does anyone know what would cause blood to clot in the test tube & should I be concerned about this?

  • Hi I only wish I did know the answer. It certainly sounds unusual. It makes me think you are the APS patient. Have you had your blood test results back yet and do you know what they were specifically looking at?

  • I don't know what they were looking for specifically, but they said all test results came back normal. But that doesn't reassure me any because when my husband's lungs were full of PE's, his Titer test came back reading very high for blood clots, yet the doctor said his tests were normal & sent him home with bronchitis!

  • This has happened to me for many years, it happened to me just last week when i was in hospital. Ive always presumed it was down to Apls but its an interesting question. I think I'll ask next time i see the consultant

  • I asked the nurse about this, but of course, the nurse isn't allowed to say anything & the doctors said everything was normal. I don't trust them. Let me know what you find out the next time you see your consultant. My husband won't be seeing his hematologist for 3 months, I think, maybe 6 months. I'd like to find out before then.

  • I will certainly let you know if i can get any info

  • I appreciate your help with this. Thanks, both you & Jade.

  • I have tried to look on the web but havent found anything helpful no matter how i phrase the questiin it just takes me to a page about general blood tests but i will keep digging

  • Thanks, magaretjo. I usually do a lot of research myself, but I haven't felt up to spending much time on the computer since I hit my head so hard when I fainted. I really appreciate your help in researching this for me.
