Also Known As
Histocompatibility Leukocyte A Antigen, Human Leukocyte A Antigen, Human Lymphocyte Antigen B27
The Purpose of an HLA B27 Test
Your white blood cells are important immune system defenders in the fight against germs and disease. But if you have the human leukocyte antigen B27 (HLA B27) on the surface of your white blood cells, that can lead to autoimmune diseases characterized by inflammation and painful joints, including reactive arthritis and ankylosing spondylitis, as well as another condition, anterior uveitis, with inflammation that damages the eyes.
What Does the HLA B27 Blood Test Measure?
A human leukocyte antigen B27 test determines if you have this antigen in your blood.
Who Should Take a Human Leukocyte Antigen B27 Test?
If you’re experiencing unexplained joint pain, particularly in the back and neck, then you may need to be tested for HLA B27.
HLA B27 Testing Preparation
You don’t have to follow any special instructions to prepare for the HLA B27 antigen test.
HLA B27 Test Results
Test results come back either positive or negative. A positive test confirms that you have the HLA B27 antigen. This may require further investigation, which can include blood, urine, and imaging tests (including x-rays and MRIs). If you need a physician to consult with about a positive HLA B27 test result, we’re here to help you by offering convenient telehealth appointments with one of our board-certified physicians.
