Can a person with hemolytic anemia donate blood?

Unwise.: If you have hemolytic anemia, you probably need to keep all the blood cells you've got! there are many different causes for hemolytic anemia. Check with your local red cross to find out if you qualify.

Usually No: Causes of hemolytic anemia include inherited metabolism or cell membrane disorders and acquired, e.G from antibodies. In either case the average survival of the red cells is shortened, sometimes severely and using such rbcs for transfusion would subject the recipient to more rapid loss of the transfused cells than is desirable, hence we do not use such donor sources.
