In the Venn diagram, blood with the Rh antigen is labeled positive and blood lacking the Rh antigen is labeled negative. The region where the three circles intersect represents type AB+, indicating that a person with this blood type has the antigens A, B, and Rh. Observe that type O blood (both positive and negative) lacks A and B antigens. Type O -lacks all three antigens, A, B, and Rh.
In blood transfusions, the recipient must have all or more of the antigens present in the donor’s blood. This discovery rescued surgery patients from random, often lethal transfusions. This knowledge made the massive blood drives during World War I possible. Eventually, it made the modern blood bank possible as well.
