ABSTRACT
The result of this study show that the determination rate of the first screening test of Rhesus group D antigens negativity was 1.2%, where as the confirmation analysis decreased this rate to 1.18%. Similarly, the determination rate of the Kell K-antigen positivity rate was 0.9%. where as the confirmation test decreased this rate up-to ().X5%. These result show, that it is necessary to use confirmation test in routine diagnosis of blood sub-group determination. The Rh blood group system is of considerable importance in transfusion and clinical medicine. We have determined some clinically important red cell antigens such as C,c I), E,e in 97 Rh (+) blood donors, using the monoclonal antibodies "Erithrotest-Tsoliclon", produced at the Hematology company. Russian Federation. Among these Rh (•) blood donors prevail RIR2, R1R1 .R2R2 phenotypes accounting for 36.1%, 27.X% and 11.3% respectively. Among these Rh (-) blood donors prevail rr. rr'.rr" phenotypes accounting for 74%, 16% and 4% respectively.
