Individuals either have, or do not have, the Rhesus factor (or Rh D antigen) on the surface of their red blood cells. This is usually indicated by 'RhD positive' (does have the RhD antigen) or 'RhD negative' (does not have the antigen) suffix to the ABO blood type. Unlike the ABO antigens, the only ways antibodies are developed against the Rh factor are through placental sensitization or translation. That is, if a person who is RhD-negative has never been exposed to the RhD antigen, they do not possess the RhD antibody.[1] The 'RhD-' suffix is often shortened to 'D pos'/'D neg', 'RhD pos'/RhD neg', or +/-. The latter is generally not preferred in research or medical situations, because it can be altered or obscured accidentally. There may be prenatal danger to the fetus when a pregnant woman is RhD-negative and the biological father is RhD-positive.
