What Is HLA-B27 Test
The HLA-B27 (Human Leukocyte Antigen) Test detects the presence of the HLA-B27 (or human leukocyte antigen B27 antigen), a protein present on the surface of white blood cells. This test forecasts the likelihood of acquiring autoimmune disorders such ankylosing spondylitis and reactive arthritis. It is important to note, however, that not all people who test positive for HLA-B27 suffer these illnesses. These disorders and their symptoms can affect anyone, including people who lack HLA-B27.

Further medical evaluation and diagnostic tests may be required to confirm a diagnosis and determine the best course of treatment.
