What's this test for?

This test is ideal if you're experiencing recurring mouth sores, genital ulcers, eye inflammation, or unexplained gastrointestinal symptoms that keep coming back without a clear cause. These symptoms can point to Behcet's disease, a rare condition that inflames blood vessels throughout the body. Checking for the HLA-B51 genetic marker can help you understand if you carry a trait strongly linked to this condition.

What's included in this test?

This test looks specifically at one genetic marker, HLA-B51, which research shows has the strongest known association with Behcet's disease out of any genetic marker studied so far. Testing for this single marker gives you a piece of the puzzle when trying to understand recurring ulcers, eye inflammation, or vessel-related symptoms, even though it isn't used alone to diagnose the condition.

What happens after I get my results?

Your results will show up in your account along with an explanation of what a positive or negative result means for this marker. If your result is positive, a practical next step is discussing your symptom pattern with a specialist familiar with inflammatory conditions, since this marker alone doesn't confirm the disease. You can download a standard lab report from your account at any time, and if you retest in the future, the trends feature lets you keep a record of your results over time.

How can I naturally support blood vessel and immune health?

Eating a diet rich in anti-inflammatory foods like leafy greens, fatty fish, and berries can help calm overall inflammation in your body. Getting consistent sleep and managing stress through activities like walking or meditation also supports healthy immune function. Avoiding smoking and limiting processed foods are additional steps that may help reduce flare-ups of inflammatory symptoms.

When will I get my results?

Results for this test are typically ready within about 7 days of your sample being processed at the lab. You'll receive a notification once your results are available in your account. This timeframe allows for the specialized genetic analysis needed to detect the HLA-B51 marker accurately.

Who should consider this test?

This test is a good option for people with recurring mouth or genital ulcers, unexplained eye inflammation, or a family history of Behcet's disease. It's also worth considering if you have ancestry from regions along the historic Silk Route, including Eastern Asia, the Middle East, and the Mediterranean, where the condition is more common. People with unexplained, repeating inflammatory symptoms in multiple parts of the body may also benefit.

What symptoms indicate I may need this test?

Common symptoms include painful sores in the mouth or on the genitals that keep returning, redness or pain in the eyes, and skin bumps or sores. Some people also experience joint pain, stomach issues, or blood vessel inflammation that shows up as swelling or clotting. If these symptoms come and go over months or years without explanation, this test may provide useful information.

What is HLA-B51 and why does it matter?

HLA-B51 is a genetic marker, part of a family of markers that help your immune system recognize what belongs in your body and what doesn't. Certain versions of this marker, especially HLA-B*51:02, are found much more often in people who have Behcet's disease compared to the general population. Knowing whether you carry this marker adds helpful context to your overall symptom picture, though it doesn't confirm or rule out the disease by itself.

What does a positive HLA-B51 result mean?

A positive result means you carry a genetic marker that is more common in people with Behcet's disease, but it does not mean you definitely have the condition. Many people with this marker never develop any symptoms at all. It's most useful as one piece of information combined with your symptom history when trying to understand recurring ulcers or inflammation.

How often should I retest?

Since HLA-B51 is a genetic marker, it doesn't change over your lifetime, so retesting this specific marker generally isn't necessary once you have a result. If your symptoms change or worsen over time, tracking those symptoms alongside this result is more useful than repeating the genetic test. Keep your original result on file in your account for future reference.
