Detailed explanation-1: -A person with the Rh positive factor will not make anti-Rh antibodies. Those with Rh negative factor will produce the antibodies. Therefore, someone with Rh+ blood can receive both Rh+ and Rh-transfusions, but those with Rh-can only receive Rh-blood.
Detailed explanation-2: -If your blood has the B antigen but not the Rh antigen, your blood type is B-negative (B–). Rh blood type is even more important for pregnant women. A problem can occur when a woman who has Rh-negative blood becomes pregnant with a baby (fetus) that has Rh-positive blood. This is called Rh incompatibility.
Detailed explanation-3: -Most Rh antibodies are IgG, subclasses IgG1 and IgG3 (IgG2 and IgG4 have also been detected), and some sera have an IgM component. Rh antibodies do not activate complement, although two rare exceptions have been reported.
Detailed explanation-4: -Rh factor is an inherited protein found on the surface of red blood cells. If your blood has the protein, you’re Rh positive. If your blood doesn’t have the protein, you’re Rh negative. The “+” or “–” you might see after your blood type refers to Rh positive or Rh negative.
