How Did the Rh Factor Get Its Name

Just as we inherit our blood type “letter” from our parents, we inherit the Rh factor from them as well. Each person has two Rh factors in their genetics, one from each parent. The only way for someone to have a negative blood type is for both parents to have at least one negative factor.

How was the Rh blood factor discovered?

Abstract. The Lutheran blood group system consists of 19 antigens: four pairs of antithetical antigens–Lu(a)/Lu(b), Lu6/Lu9, Lu8/Lu14, and Au(a)/Au(b)–and 11 antigens of very high frequency. These antigens are located on four of the five immunoglobulin-like domains of both isoforms of the Lutheran glycoprotein.
