IMMUNOLOGY OF ABO AND RH BLOOD TYPES

EACH BLOOD TYPE IS NAMED ACCORDING TO THE ANTIGENS ON ITS SURFACE

EACH BLOOD TYPE PRODUCES ANTIBODIES AGAINST ANY ANTIGEN IT DOES NOT POSSESS – AGAINST ANY ANTIGEN THAT IS FOREIGN

WHEN INCOMPATIBLE BLOOD TYPES ARE MIXED, A DANGEROUS CONDITION RESULTS CALLED AGGLUTINATION

THERE ARE THREE MAJOR ANTIGENS ON THE SURFACE OF RED BLOOD CELLS

- A ANTIGEN - B ANTIGEN RH ANTIGEN

LIKEWISE THERE ARE THREE IMPORTANT ANTIBODY TYPES PRODUCED AGAINST EACH OF THE THREE ANTIGENS

ANTIBODIES ANTI - A ANTI - B ANTI - RH

TYPE A- BLOOD CONTAINS A ANTIGEN MAKES ANTIBODIES AGAINST B BLOOD – ANTI-B & RH FACTOR

TYPE B+ BLOOD MAKES B ANTIGEN MAKES RH ANTIGEN MAKES ANTIBODIES AGAINST A BLOOD – ANTI -A

TYPE AB- BLOOD CONTAINS BOTH A AND B ANTIGENS MAKES NEITHER ANTI-A OR ANTI-B BOTH ARE SELF PROTEINS MAKES ANTI –RH ANTIBODIES

TYPE O- BLOOD NEITHERCONTAINS NEITHER A NOR B NOR RH ANTIGENS MAKES ANTI-A AND ANTI-B AND ANTI –RH ANTIBODIES

TYPE A+ BLOOD CAN GIVE BLOOD TO …… CAN RECEIVE BLOOD FROM….
