Which antigen is present in Rh-positive individuals?

In the Rh blood group, the defining factor is the presence of the D antigen on red blood cells. If the D antigen is present, the person is Rh-positive; if it’s absent, they are Rh-negative. A and B antigens belong to the ABO system, and O antigen isn’t the marker used to define Rh status. So the antigen present in Rh-positive individuals is the D antigen (RhD).
