Tests that categorize your blood according to the major human blood group ABO system (O, A, B, AB). Rh Factor testing determines whether the configuration is rh-positive or rh-negative.
This is generally done during your first prenatal visit because this can affect your pregnancy. Your pregnancy likely needs special care if you are Rh negative. A baby can inherit the Rh factor from either parent. This can also be done to determine compatibility for blood transfusions, and more.
