Donor antibody detection using plasma in place of serum

Twenty-two types of erythrocyte antibodies from 53 individuals were studied for their detectability in serum versus CPD, ACD and EDTA plasms samples. In no specimen thus far tested was there an antibody detectable in serum but not detectable in plasma. These results suggest that blood samples collected in anticoagulant are suitable not only for antigen typing but also for antibody screening.
