HLA-DR09 (DR9) is a HLA-DR serotype that recognizes the DRB1*0901 gene product.

Serology + DR9 recognition of some DRB1*0901 allelesderived from IMGT/HLA DRB1* DR9 Sample allele % % % size (N) 0901 95 1058

The serological reaction of DR9 is relatively good. The serology of DRB1*0902 to *0906 serotypes is unknown.
