What do antigens on red blood cells determine?

Explanation:
Antigens on red blood cells are the markers that define an individual's blood type, including A, B, and the Rh factor. The A and B antigens determine ABO type, while the presence or absence of the Rh D antigen defines Rh status. These surface molecules shape how the immune system recognizes cells and guide transfusion compatibility. Oxygen transport capacity depends on hemoglobin levels and red blood cell mass, not which antigens are present. White blood cell production comes from bone marrow and is driven by growth factors and cytokines, not RBC surface antigens. Platelet function relates to platelets and clotting pathways, separate from red blood cell antigen profiles.
