A classification system for human blood that identifies four major blood types based on the presence or absence of two antigens, A and B, on red blood cells. In 1900, he found that red blood cells would clump together (agglutinate) when mixed in test tubes with sera from different persons, and that some human blood also agglutinated with animal blood. The four basic ABO phenotypes are O, A, B, and AB. A blood type (also called a blood group) is a classification of blood, based on the presence and absence of antibodies and inherited antigenic substances on the surface of red blood cells (RBCs).. inherited from both parents. It is the foundation of crossmatching blood samples between donors and recipients to find blood that is safe to transfuse. The ABO system is based on which type of antigen is present on the RBC. What types of biochemicals are surface markers on red blood cells? Blood type categorized based on the presence of antigens and antibodies.These antigens are proteins, glycoprotein, glycolipid or carbohydrates.The total 36 human blood groups are discovered by international society of blood transfusion (ISBT). 1 Unlike protein-based blood group systems, red blood cell (RBC) glycan antigens (eg, ABH, i/I, Lewis blood groups) rely on glycosyltransferases to add specific glycan moieties on to protein and lipid constructs. You can be A, B, AB or O under this system. Blood test results, Blood tests, Rare Blood types, blood disorders. However, the main Rh classification is based on one single antigen of special importance, called the D antigen. A series of related blood types constitutes a blood group system, such as the Rh or ABO system. cross matching: blood test for identification of blood type using antibodies and small samples of blood A blood type (also called a blood group) is a classification of blood based on the presence or absence of antigenic substances on the surface of red blood cells (RBCs).

The other important blood group system is Rh, which determines a (+) or (-) after the ABO classification. The ABO group: Two of the different antigens on the red blood cells' surface is known as antigen A and B. Anti-A or anti-B isoagglutinins (alloantibodies) are present only in the blood sera of individuals not possessing that specificity. The ABO system is the main blood grouping system behind the principle that helps classify people into one of the following four groups, i.e., A, B, AB or O.
