HLA B 27 Disease Association

This test checks for HLA-B27, a specific protein found on the surface of your white blood cells. It is often ordered to investigate the cause of chronic joint pain, stiffness, or inflammation in the spine, as this protein is linked to certain autoimmune conditions like ankylosing spondylitis. The results help doctors determine if your symptoms are likely caused by these specific inflammatory disorders. However, testing positive does not confirm a diagnosis, as many healthy people carry this marker without developing a disease.
