Rh Negative Bloodlines in History
Each person’s blood is one of four major types: A, B, AB, or O. Blood types are determined by the types of antigens on the blood cells. Antigens are proteins on the surface of blood cells that can cause a response from the immune system. The Rh factor is a type of protein on the surface of red blood cells. Most people who have the Rh factor are Rh-positive. Those who do not have the Rh factor are Rh-negative. If one is Rh-negative, s/he may develop antibodies to a Rh-positive baby. If a small amount of the baby’s blood mixes with one's blood, which often happens, the body may respond as if it were allergic to the baby. The body may make antibodies to the Rh antigens in the baby’s blood. This means one has become sensitized and the antibodies can cross the placenta and attack the baby’s blood.
