What's this test for?

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.

How should I prepare for this test?

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.

What's included in this test?

HLA-B27 Antigen

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 happens after I get my results?
You'll receive detailed doctor notes in simple language explaining whether the HLA-B27 antigen was detected and what that means for your joint symptoms and autoimmune risk. The notes include personalized recommendations on managing inflammation, when to see a rheumatologist, and lifestyle modifications to support joint health. Along with your standard lab report, you can track this result over time, which is especially helpful if you develop new symptoms or need to monitor treatment progress.
When will I get my results?
Most HLA-B27 antigen test results are available within 3-5 business days after your blood sample reaches the lab. You'll receive an email notification when your results are ready to view in your secure online account, complete with doctor notes explaining what your results mean.
Who should consider getting this test?
This test is particularly important for people experiencing chronic lower back pain or stiffness that lasts more than three months, especially if it improves with exercise and worsens with rest. It's also valuable for those with unexplained eye inflammation, heel pain, or a family history of ankylosing spondylitis or reactive arthritis. Anyone whose doctor suspects an autoimmune cause for their joint symptoms should consider this screening.
What symptoms indicate I may need this test?
Common symptoms include chronic lower back pain and stiffness that's worse in the morning or after periods of rest, reduced flexibility in your spine, pain in your hips or buttocks, and heel pain. You might also experience eye inflammation, fatigue, or pain that improves with movement and exercise rather than rest, which is unusual for typical back pain.
What does a positive HLA-B27 result mean?
A positive result means you carry the HLA-B27 antigen, which increases your risk for certain autoimmune conditions like ankylosing spondylitis and reactive arthritis. However, it's important to know that only about 2-8% of people with HLA-B27 actually develop these conditions. Your doctor will consider your symptoms, medical history, and other tests to determine if you have an active autoimmune condition or just carry the genetic marker.
How can I naturally support my joint health if I have HLA-B27?
Regular low-impact exercise like swimming, yoga, and stretching helps maintain flexibility and reduce stiffness. An anti-inflammatory diet rich in omega-3 fatty acids from fish, colorful vegetables, and whole grains can help manage inflammation. Getting adequate sleep, managing stress, maintaining good posture, and avoiding smoking are also important for protecting your joints and spine.
How often should I monitor my condition if I'm HLA-B27 positive?
If you test positive but have no symptoms, annual check-ups with your doctor are typically sufficient to monitor for any developing issues. If you have symptoms or a diagnosed condition like ankylosing spondylitis, your rheumatologist will likely want to see you every 3-6 months to track disease progression and adjust treatment. The HLA-B27 test itself doesn't need to be repeated, as your genetic status doesn't change.

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.

* Regular blood test results (e.g., CBC) typically start arriving the next business day after sample collection. More complex tests, such as hormone panels, may take up to 10–15 business days due to their complexity.
