This test is ideal if you're experiencing unexplained chronic joint pain, stiffness (especially in your lower back and hips), or inflammation that seems worse in the morning. It helps identify whether you carry the HLA-B27 antigen, which is strongly linked to autoimmune conditions like ankylosing spondylitis and reactive arthritis. Many people use this test when their joint pain isn't explained by injury or typical arthritis, or when they have a family history of these conditions.
No special preparation is needed for this test. You don't need to fast or avoid any foods or medications before testing. This is a simple blood draw that can be done at any time of day, making it convenient to schedule around your routine.
This test detects the presence of HLA-B27, a specific protein found on the surface of your white blood cells. This genetic marker is found in 90% of people with ankylosing spondylitis and 80% of those with reactive arthritis, making it a valuable indicator when investigating chronic joint pain and inflammation. Having this antigen means you're 10 times more likely to develop these conditions compared to people without it, though many people with HLA-B27 never develop symptoms.
What this means
Your test came back negative, meaning the HLA-B27 antigen was not detected in your blood. This is the most common result and significantly reduces the likelihood that your symptoms are caused by ankylosing spondylitis or reactive arthritis, though it doesn't completely rule out these conditions.
Recommended actions
Continue working with your doctor to identify other causes of joint pain or inflammation
Maintain anti-inflammatory lifestyle habits including regular exercise and healthy diet
Keep a symptom journal to track patterns in your pain and stiffness
Consider other diagnostic tests if symptoms persist or worsen
