Broad, Splits and Associated Antigens
Previous content on this page has been moved to HLA Antigens due to user feedback, to better reflect the pages title and improve understanding of how serological definitions are interpreted.
This page has been updated following the 2026 Nomenclature Report. Antigens given in bold type have been assigned since the 2010 Nomenclature report. The HLA-D and HLA-DP specificities listed are the cellularly defined specificities.
In addition to the specificities listed here, the 2026 Nomenclature Report also expanded the nomenclature for associated antigens. For a complete list of associated antigens, please refer to the Associated Antigens page.
Entries with brackets, i.e. A25(10) show the split and it's associated broad antigen.
