What is HLA-B27 testing?

Generally, HLA-B27, short for human leukocyte antigen B27, is a type of human leukocyte antigen. The HLA-B27 test is a method used to detect the presence of the HLA-B27 gene, primarily aimed at evaluating the likelihood of spondyloarthritis. Specific analysis is as follows:

The HLA-B27 test is usually performed via a blood test and is mainly used in diagnosing and assessing diseases associated with HLA-B27, such as ankylosing spondylitis, psoriatic arthritis, and enteropathic arthritis. These conditions are somewhat linked to the presence of the HLA-B27 gene, although not all individuals affected by these diseases carry the HLA-B27 gene.

It is recommended to fast before undergoing the HLA-B27 test to avoid any factors that might interfere with the test results. The test outcome can assist physicians in diagnosing diseases and formulating appropriate treatment plans.
