My 24 month old daughter has an unknown bone marrow failure disorder that has yet to be diagnosed. Her hemoglobin level was at 2.6 (at 22 months) when I took her to the hospital with really no other symptoms other than looking severely pale. (With further digging into medical reports I found that she was at 7.6 at the age of 12 months). She has had several transfusions since obviously! She usually drops down to 7 before a transfusion is done which usually brings her up to a 9, maybe a ten. This flux of hemoglobin usually occurs on a monthly basis. My question?! Is this up and down okay for her being so young and during developing stages of her life? Should the range be higher and smaller?
