This test is used to determine whether you have human leukocyte antigen B27 (HLA-B27) on the surface of your cells, and to help assess the likelihood that you have an autoimmune disorder associated with the presence of HLA-B27.
This test detects the presence of human leukocyte antigen B27 (HLA-B27) on the surface of white blood cells - a group of proteins that help the body's immune system to identify its own cells and to distinguish between 'self' and 'nonself'. HLA-B27 is found in about 5-10% of the Australian population. Its presence has been associated with several autoimmune disorders, the most common of these disorders is ankylosing spondylitis (AS).
The best time to do this test is first thing in the morning.
