Why is HLA called an antigen? HLA genes are highly polymorphic, which means that they have many different alleles, allowing them to fine-tune the adaptive immune system.

What do you need to know about the HLA-B27 test?

What do you need to know about the HLA-B27 test? The term HLA-B27 is also used to refer to the gene that codes for the HLA-B27 protein. The HLA-B27 test determines the presence or absence of HLA-B27 protein on the surface of a person’s white blood cells.

Can you get ankylosing spondylitis with HLA-B27? While HLA-B27 has not been established as a cause of any of these disorders, there is a higher prevalence of the antigen in those affected.
