Answer 2

Rh factor is an antigen found on the surface of red blood cells. Red blood cells with the antigen are said to be Rh positive, while those without are said to be Rh negative. Blood used in transfusions must match the donor and recipient's Rh and ABO blood type as Rh negative patients will develop anemia when given Rh positive blood.
