Agglutination reaction (ABO blood grouping)

Content – ‘’Agglutination is the process that occur if an antigen is mixed with its corresponding antibody called ‘Isoagglutinin/Agglutinins’. This term ‘agglutination’ is commonly used in blood grouping.
ABO blood grouping : Karl Landsteiner discovered human blood groups.
AB blood group was found by Decastrello and Sturli in 1902.
Antiserum A + Blood sample = Agglutination = Blood group A
Antiserum B + blood sample = Agglutination = Blood group B
Antiserum A+B + Blood sample = Agglutination = Blood group AB
Antiserum A+B + Blood sample = NO Agglutination = Blood group O
