Sometimes blood can be specially treated to allow recipients to get a kidney from a living donor who has an incompatible or non-matching blood group. To prevent immediate rejection of the kidney, the recipient undergoes plasmapherisis or a plasma exchange treatment before and after the transplant to remove harmful antibodies from the blood. Antibodies are part of the immune system. They are proteins produced by white blood cells to fight infections. See similar questions...

Statistically, the rarest is AB Rh negative. However, at the blood center we think of the rarest type as being the one we don't have when we need it the most. Far more people have type O blood, and those are the donors we need most. While scientists are currently working on it, there is no substitute for blood. Donors are still the only source for the "Gift of Life." See similar questions...

A group of tests that are important for diagnosing lupus will be performed. The results of these tests (serology) will be sent to you if you choose to receive them. The DNA in your blood will be analyzed to determine which genes may be involved in lupus and to address other scientific questions about lupus as they arise. A permanent cell line will be established and this cell line may be used for other approved lupus research at a later time. See similar questions...

People with O Rh negative blood are considered universal blood donors because patients of all blood types can receive O Rh Negative blood. It is important to remember that all blood types are needed to meet the needs of patients for blood and blood products.

By selecting a donor whose blood type matches the husband's/partner's blood type, patients may feel more secure about issues related to confidentiality. The donor's blood type may be medically important to consider if the mother is Rh negative (Rh-). These women may develop antibodies to a fetus that is Rh positive. See similar questions...
