Blood Type Grouping

The Blood Type Test will determine the common blood types A,B,O,AB and Rhesus(D).

Includes: ABO blood grouping and Rh typing (including test for "weak D", if applicable).

Blood type tests are done before a person gets a blood transfusion and to check a pregnant woman's blood type. Human blood is typed by certain markers (called antigens) on the surface of red blood cells. Blood type may also be done to see if two people are likely to be blood relatives.

The most important antigens are blood group antigens (ABO) and the Rh antigen. Therefore, the two most common blood type tests are the ABO and Rh tests.
