    Your blood type is determined (genetically) by the presence or absence of specific surface antigens on the membrane of the RBC. The most important RBC surface antigens are A, B and Rh.

        Blood can be either Rh positive(Rh+) or Rh negative (Rh-) depending on the presence (Rh+) or absence of the Rh antigen (Rh-) on the surface of the cell.


        Unlike the ABO system, type Rh- blood does not normally carry anti-Rh antibodies, unless the individual has been sensitized by previous exposure (usually pregnancy).


        The most common blood type is O+.

      What does A Rh D POS mean as your blood group?

      A Rh D POS signifies that your blood type is A with the presence of the Rh factor (Rhesus factor D antigen). This means you have A antigens on the surface of your red blood cells and are Rh positive, indicating that you can receive blood from A positive, A negative, O positive, and O negative blood types. It's important in blood transfusions and pregnancy, as it can affect compatibility between blood types.

      If your parents are blood type O negative and b negative does that mean that you will have a negative blood type?

      Not necessarily. Your blood type is determined by the combination of alleles you inherit from your parents, but it's not as simple as just inheriting the negative Rh factor. Depending on the specific alleles you inherit, you could end up with a positive blood type even if both parents are negative.
