Blood Type Predictor

You may use the following predictor to determine the most likely blood types of offspring born to parents with the blood types you enter into the predictor.

The predictor will also provide you with the blood types of donors which would provide the same blood type results in the offspring. Please consult your physician regarding ABO and Rh incompatability. Women who are Rh- and select a Rh+ donor may need to be treated with rhogam during pregnancy. Please consult your physician.
