Would you like to donate blood for a study of stored red blood cells? This study is evaluating how blood donors affect the stability of stored red blood cells. After collecting a blood sample from a healthy donor, researchers treat the red blood cells with a B vitamin called biotin and then store the sample. After about 1 week, some of the cells are transfused back into the donor to check how many of the red blood cells are still healthy after storage. After a few more weeks, more of the stored cells are transfused and tested again. To participate, your blood must meet certain requirements and you must be healthy, 18 years old or older, and weigh at least 110 pounds. This study is located in Pittsburgh, Pennsylvania.
