HLA-A25 (A25) is a human leukocyte antigen serotype within HLA-A serotype group. The serotype is determined by the antibody recognition of α25 subset of HLA-A α-chains. For A25, the alpha "A" chain are encoded by the HLA-A*25 allele group and the β-chain are encoded by B2M locus.[1] This group currently is dominated by A*2501. A25 and A*25 are almost synonymous in meaning. A25 is a split antigen of the broad antigen serotype A10. A25 is a sister serotype of A26A34A43, and A66.

A25 is more common in SW Asia to NW Europe. A25 is believed to have been formed by a single gene conversion between another HLA-A and the A*2601 allele.[2].

A25 reasonably good serotyping with no overt false recognition..
