HLA B27 Test
HLA B27 Testing Center
The human leukocyte antigen B27 is known as HLA-B27. A blood test called HLA-B27 is used to look for a particular protein on white blood cells that may be the cause of an autoimmune condition like Ankylosing Spondylitis (AS).
The majority of HLA (antigens) defend the body from damage, however HLA-B27 does the exact reverse. Your immune system will become dysfunctional as a result.
