Athletes may undergo blood transfusion to increase their red cell mass and the oxygen carrying capacity of their blood in order to confer a competitive advantage. Allogeneic transfusions are normally mismatched at one or more minor blood group antigens. The most sensitive and accurate method known to detect this form of blood doping is flow cytometry. Low percentages of antigen-positive and antigen-negative red blood cells (RBCs) can be quantitated using suitable specific alloantibodies and careful analysis. By testing blood samples taken at various times, a reduction in the percentage of a minor population of RBCs will indicate transfusion has occurred.
运动员可能会接受输血以增加其红细胞量和血液的携氧能力，从而获得竞争优势。异体输血通常在一个或多个次要血型抗原上不匹配。已知检测这种血液兴奋剂形式最灵敏、最准确的方法是流式细胞术。使用合适的特异性同种抗体并进行仔细分析，可以对低比例的抗原阳性和抗原阴性红细胞（RBC）进行定量。通过检测在不同时间采集的血样，少数RBC群体百分比的降低将表明发生了输血。
