Blood typing involves using antiserum reagents A, B, and D to determine a person's blood type through agglutination, which is the clumping of red blood cells caused by the introduction of antibodies in the antiserum reacting with antigens on the red blood cells. The procedure involves using a lancet to draw blood, placing it on a glass slide, mixing it with the antiserum reagents, and observing if agglutination occurs which would indicate the presence or absence of the A, B, or D antigens and determine the person's blood type.
