How many blood group systems are there ISBT?
There are 30 blood group systems recognized by the International Society for Blood Transfusion (ISBT) (Table 1). Some systems contain only one determinant, while others, such as Rh and MNS, contain many.
What are the 36 blood group systems?
There are eight main blood types: A positive, A negative, B positive, B negative, AB positive, AB negative, O positive and O negative. The positive and negative refers to your Rh type (once called Rhesus). In addition to ABO and Rh, there are 34 other recognised blood types, called blood group systems.
How many blood grouping systems are there?
There are 4 main blood groups (types of blood) – A, B, AB and O. Your blood group is determined by the genes you inherit from your parents. Each group can be either RhD positive or RhD negative, which means in total there are 8 blood groups.
What are the ABO and Rh systems?
ABO blood groups are the most basic system of blood typing. This system divides blood into four groups – A, B, AB and O. The other main grouping used is the Rhesus (Rh) system, which is either negative or positive. Your blood group is a combination of the ABO system and the Rh system: for example, O negative.
What is the I blood group system?
The I blood group system was promoted to its own system in 2002 after the I (GCNT2) gene located on chromosome 6 (6p24.2) was identified as encoding the glycosyltransferase responsible for converting i-active straight oligosaccharide chains to I-active branched chains.
Are all antigens receiving ISBT numbers inherited?
All antigens receiving ISBT numbers must have been shown to be inherited characters. The information presented here is an update of one of our publications. Each antigen belonging to a blood group system is identified by a 6-digit number.
