Also known as: Blood Grouping and Rh Typing, Blood Type, Group and Type, Type and Rh

The results of blood typing tests will tell you if you are group A, B, AB, or O and whether you are Rh negative or positive depending on what antigens are present on your red blood cells. The results will tell the health professional what blood or blood components will be safe for you to receive. The results will tell a pregnant woman whether she is Rh positive or Rh negative and whether she may be a candidate for receiving Rh immune globulin to prevent her from potentially developing antibodies against her fetus’ blood cells. Blood typing will also tell the personnel at collection facilities what blood type you are donating and who can safely receive your blood.
