When giving blood to control high hematocrit and hemoglobin my ferritin drops to like 15? Is that a problem?
AlphaMD's Answer
Ferritin is one of the building blocks of hemoglobin, which is part of red blood cells. When you donate a unit of blood, on average your hematocrit will drop on average 3%.Your body will try to replete the blood that was lost/donated, pulling from your ferritin stores.This is not a problem, so long as you have adequate iron intake, the ferritin will be restored as well.
