This test, sometimes referred to as an ABO/Rh test, will tell you if your blood type is A+, A-, B+, B-, AB+, AB-, O+ or O-. This information is especially important for patients who need a blood transfusion, so that doctors know which type of blood they are able to safely receive. The results will also determine if a pregnant woman is Rh positive or negative, impacting whether or not she is a candidate for an Rh immune globulin immunization.
