As defined by the ISBT, a blood group system “consists of one or more antigens controlled at a single gene locus, or by two or more very closely linked homologousgenes with little or no observable recombination between them
Each system is genetically distinct. To date, there are 30 blood group systems and most have antithetical antigens (Ex K and k antigen)
Blood group collections are antigens that have a biochemical, serologic, or genetic relationship but do not meet the criteria for a system. Antigens classified as a collection are assigned a 200 number.
All remaining RBC antigens that are not associated with a system or a collection are catalogued into the 700 series of low-prevalence antigens or the 901 series of high-prevalence antigens
