how much blood for ferritin be taken out
Regular blood donation can be done every 8 weeks. A person with severe iron overload may need to give blood as much as 8 times in a single month! The goal is to bring blood ferritin levels to an ideal range of 50-150ng/mL. Depending on the amount of iron overload at the time of diagnosis, reaching normal levels can require several phlebotomies. Serum ferritin drops about 30ng/mL with each full unit (500cc) of blood removed.
