Detailed explanation-1: -The red blood cell antigens k, Jsb, Kpb, and Lub are all high-incidence antigens. The presence of these antigens in blood products can cause transfusion reactions in patients. It can also be difficult to find blood products without these antigens.
Detailed explanation-2: -Detection of anti-A1 antibodies was performed for A2 and A2B blood group samples. In this study, A blood group showed the highest frequency (40.1%), followed by O (27.09%), then B (24.97%), and lastly AB (7.8%).
Detailed explanation-3: -The k antigen (KEL2) was identified in 1949 and it is a high-frequency antigen in most populations. The prevalence is 99.8% in Caucasians and 100% in Blacks.
Detailed explanation-4: -There are 4 main blood groups defined by the ABO system: blood group A – has A antigens on the red blood cells with anti-B antibodies in the plasma. blood group B – has B antigens with anti-A antibodies in the plasma. blood group O – has no antigens, but both anti-A and anti-B antibodies in the plasma.
