About and Activities

Learn more about the Red Cell Immunogenetics and Blood Group Terminology Working Party and its activities.


We are involved in the genetically based numerical terminology for red cell surface antigens. By definition, these antigens must be defined serologically by the use of specific antibodies. All antigens receive a unique ISBT number and must have been shown to be inherited characters. We advise, maintain and monitor the terminology for blood group genes and genetic classification for blood group antigens. We offer members the opportunity to participate in the development/maintenance of nomenclature. We discuss all issues related to molecular typing as well as the analysis of blood group genes.

Our Chairpersons are Catherine Hyland and Christoph Gassner.



We meet at the ISBT congresses and maintain up-to-date catalogues of blood group antigens and alleles. We also write guidelines for nomenclature.
