Detailed explanation-1: -The liquid part of your blood without cells (serum) is mixed with blood that is known to be type A and type B. People with type A blood have anti-B antibodies. People with type B blood have anti-A antibodies. Type O blood contains both types of antibodies. The 2 steps above can accurately determine your blood type.
Detailed explanation-2: -If your blood cells clump when mixed with anti-Rh antibodies, you have Rh+ blood. If they don’t clump, you have Rh-blood.
Detailed explanation-3: -But if you have type O blood, your red blood cells have no A or B markers. So: Your body will have both A and B antibodies and will therefore feel the need to defend itself against A, B, and AB blood. A person with O blood can only get a transfusion with O blood.
