I had my numbers all come back low other than the size of the cells on my CBC panel. My hemoglobin levels have always been on the lower side, but went down to 6.4. I needed a blood transfusion (twice actually). I had had a colonoscopy and endoscopy done (I don't remember if they had been done prior or after finding out about the low numbers, because I was also having GI issues). They had me do a bone marrow biopsy to rule out cancer, which was thankfully negative. Then I started on shots for anemia. I was going once a month at first and now every other month to have my CBC panel done and if needed I get a shot to increase the production of my hemoglobin. The shots have generally been able to get my numbers up. Even if I need a shot my level is closer to a 10 and I haven't needed any more blood transfusions since last June.
