,c antigen is most common in blacks and whites; anti-c would be most common reactive - Answer: Rh
antibodies show enhanced reactivity with enzyme pretreated cells. The M and Fya antigens are cleaved
from enzyme pretreated cells and therefore there would be no reaction between enzyme pretreated
cells and serum containing anti-M or anti-Fya. The incidence of the c antigen is 80% in whites and 96% in
blacks. The incidence of the E antigen is 29% in whites and 22% in blacks. Increased reactivity with
enzyme pretreated cells and incompatible results with 8 of 10 donor units is most likely due to anti-c.
