Hi all, I have dealt with chronic iron def. anemia for years. I have celiac disease, lymphocytic colitis, and pernicious anemia. My hemoglobin and hematocrit have always been low despite iron supplements. My hemoglobin at best would be around 10 or 11, I don't recall what me hematocrit usually was. Anyway, I just got the results from my latest CBC, my hemoglobin was 14.4 and my hematocrit was 43.5. They have NEVER been this good, even though I have been on iron supplementation for quite a while.My RBC was 5.13, which was a little high according the the reference range my lab uses. They did not do a serum iron check with my last CBC, but the previous serum iron check was 10, with the normal being between 40 - 60, I believe. I am just curious as to why it would improve so suddenly??? Nothing else has changed, iron supplementation was the same, diet the same, menstrual cycles the same, etc. Any ideas???
