That means the transfused blood must have the same antigens as your red blood cells.

Lacking the Rh factor, genetically determined antigens in red blood cells that produce immune responses. If an Rh negative woman is pregnant with an Rh positive fetus, her body will produce antibodies against the fetus's blood, causing a disease known as Rh disease. So when we say someone’s blood is “negative,” we really mean it’s Rh negative. Rh factor, or Rhesus factor, refers to a protein that can be found on the surface of red blood cells. Fun fact: “Rhesus” refers to rhesus monkeys, who also have the Rh factor gene. Rh (D) status of an individual is normally described with a positive or negative suffix after the ABO type (e.g., someone who is A Positive has the A antigen and the Rh (D) antigen, whereas someone who is A Negative lacks the Rh (D) antigen).
