A person's blood type is determined largely by genetics, and it does not change through his or her lifetime. A simple blood typing test can be performed literally anywhere by anyone through the use of specially-treated testing cards. One of the main factors that determines blood type is family genetics.
There are four main blood types (A, B, O and AB), which are determined by the presence or absence of certain antigens on the surface of red blood cells. Individuals are also typed as either Rh positive or Rh negative depending on the presence or absence of the most important red cell antigen in the Rh blood group.
