In the year 1900 Landsteiner was identified the ABO grouping system. In this an antigen type presence or absence can determines the blood group and are of 4 types:
1. A group: type A antigen is present, and body will develop antibodies against B antigen;
2. B group: type B antigen is present, and body will develop antibodies against A antigen;
3. AB group: types A and B antigens are present and body will have no antibodies;
4. O group: Absence of both A and B type antigens, and body develops antibodies against both the antigens.
