Blood Type And Agglutination

October 29, 2020

In typing for the abo antigens rbcs are mixed on a slide with antisera to the a or b blood group antigens. The typical blood typing tray contains wells for all three antisera anti a anti b and anti d and you check all of them to determine blood type.

If agglutination occurs this indicates that the donor and recipient blood types are incompatible.

Blood type and agglutination. Hemagglutination is the process by which red blood cells agglutinate meaning clump or clog. If the antigen is present on the cells they agglutinate forming a visible clump on the slide. If you are positive for the rh protein you just denote a positive sign after the identified abo type e g.

Agglutination reactions are routinely performed to type red blood cells. After the collection of samples they mixed with latex beads coated with a specific antibody or antigen. Agglutination test used in all types of body fluids to detect antigens and antibodies for example saliva urine blood cerebrospinal fluid lumbar puncture.

The agglutin involved in hemagglutination is called hemagglutinin in cross matching donor red blood cells and the recipient s serum or plasma are incubated together. B indicates that agglutination occurred in both the anti b and the anti d sera.
