MICROANATOMY

Detailed explanation-1: -It is a simple process of elimination of the possibilities. For instance, if an individual’s blood sample is agglutinated by the anti-A antibody, but not the anti-B antibody, it means that the A antigen is present but not the B antigen. Therefore, the blood type is A.

Detailed explanation-2: -Individuals with type A blood-without any prior exposure to incompatible blood-have preformed antibodies to the B antigen circulating in their blood plasma. These antibodies, referred to as anti-B antibodies, will cause agglutination and hemolysis if they ever encounter erythrocytes with B antigens.

Detailed explanation-3: -Agglutination of blood types takes place as follows: A+-Agglutination with Anti-A and Anti-Rh.

Detailed explanation-4: -The subject is blood group A if agglutination occurred with the Anti-A test serum; group B if agglutination occurred with the Anti-B test serum; group AB if agglutination occurred with both test serums, and O if there was no agglutination in either case.

Detailed explanation-5: -Answer and Explanation: If your blood agglutinates with anti-A but not anti-B sera, your ABO blood type would be type-A. Blood group testing is based on antigen and antibody interactions. The antigens are present on the red blood cells, while the sera used for testing contains the antibodies.
