I finally got the bone marrow test paperwork from my parents. The 7% number was not quite right, and I'm curious if you guys can help me through this. In fact on his bone marrow paperwork, it says he has RCMD not RAEB(the hemo doctor came up RAEB).
There are two terms lists on his bone marrow paperwork CD34 and CD45. CD34, from what I have read, is responsible hematopoietic activity in bone marrow. Which from I've read is the mechanism that deals with red stem cells turning into red blood cells(or even going to white blood cells). Is that correct? CD45 however deals with activation of T-Cells which are responsible for dealing with the immune system.
The CD34 blast count is (3% to 4%), and CD45 blast count is 7%. So when figuring out what form of MDS you have, is it correct to take the higher of the two blast counts? That's the only way I can see the hemotolgist coming up with RAEB and the hospital doctors coming up with RCMD. You can't have RAEB if your blast count is < 5%.
Or am I looking at things all wrong :P.
