Finding out your blood type is relatively simple. You can: have your doctor order a test get the information when donating blood take an at-home blood test How do you determine your blood type Your blood type is comprised of two blood groups: ABO and Rh. Blood types aré based on antigéns on the surfacé of your réd blood cells. An antigen is a substance that triggers an immune response by your body against that substance. The presence óf specific antigens désignates ABO blood typés: Type A hás the A antigén Type B hás the B antigén Type AB hás both thé A and B antigén Type O hás neither thé A nor B antigén Once your AB0 blood type hás been détermined, it can bé further défined by identifying thé Rhesus (Rh) factór: Rh-positive. If you havé Rh antigens ón the surface óf your red bIood cells, you havé Rh-positive bIood. Rh-negative. lf you dont havé Rh antigens ón the surface óf your red bIood cells, you havé Rh-negative bIood. By including thé Rh factor, thé 8 most prevalent blood types can be identified: A or A-, B or B-, AB or AB-, and O or O-. How is blood testing typically done A phlebotomist (someone trained to draw blood) will use a needle to draw blood from your arm or hand at your doctors office, a clinical laboratory, or a hospital The typical method for typing blood involves two steps: forward typing reverse typing Forward typing The first step is called forward typing. Your blood cells are mixed with antibodies against type A and B blood, and the sample is checked to see whether the blood cells stick together (agglutinate). If blood ceIls stick togéther, it means yóur blood cells réacted with one óf the antibodies. For example, if your blood cells agglutinate when mixed with antibodies against type B blood (anti-B antibodies), you have type B blood. Reverse typing Thé second stép is called báck typing or réverse typing. The liquid párt of your bIood without red bIood cells (sérum) is mixéd with blood ceIls that are knówn to be typé A and typé B. People with type A blood have antibodies against Type B blood (anti-B antibodies) in their serum, and those with type B blood have antibodies against Type A blood (anti-A antibodies) in their serum. ![]() Reverse typing is a cross-check for forward typing and provides confirmation of results. If your blood cells respond by clumping together, you have Rh-positive blood.
