Wow Triumphe - I'm with you. 5 points either way sounds horrendously inaccurate to the point of why bother testing.
riccd2001 - I had the CBC before the tfx. I usually estimate 10 points per 200 ml, and then work out what my HGB should be afterwards based on volume. I get counts done every 2 weeks and the HGB always drops, usually around 27 points. It also used to drop every time when I had weekly counts done. It would be interesting (but real inconvenient) to get daily counts. Do you get monthly transfusions, or 1 unit every 2 weeks?
I've never seen my count go up much, so I am hoping it is not lab error, but I realize it could be.
What about the WBCs, from 1.3 to 1.8 is almost a 40% difference in one day. I think WBCs and platelets probably fluctuate more than RBCs, and I didn't do anything that would have caused dehydration in 24 hrs.
Probably never know. Hope it happens again though! LOL.
