What's this test for?

This test is ideal if you're experiencing joint pain, eye inflammation, or unexplained skin reactions that your care team suspects may be linked to a genetic marker. It's also commonly used to check for a genetic marker before starting certain new medications, since some genes are linked to a higher chance of severe drug reactions. Knowing your HLA-B status can help explain symptoms and guide safer treatment choices.

What's included in this test?

This test looks at a specific set of genetic markers on the surface of your cells that play a role in how your immune system recognizes your own tissue versus foreign substances. These markers matter because certain variations are strongly linked to increased risk of specific autoimmune conditions and to reactions from certain medications. Identifying your exact genetic type gives you and any future treatment decisions a clearer picture of your personal risk profile.

What happens after I get my results?

Your results will be available in your account, and each finding is explained in plain language so you know what it means for you. If your result shows a specific genetic marker, next steps usually involve sharing this information before starting new medications or treatments, since it can affect how your body reacts to them. You can download the standard lab report anytime from your account, and since this is a one-time genetic result, there's typically no need to retest, but you can keep it saved in your trends history for future reference.

How can I naturally support a healthy immune system?

While you can't change your genetic markers, you can support your overall immune health with consistent sleep, regular movement, and a diet rich in fruits, vegetables, and lean protein. Managing stress through activities like meditation or light exercise can also help reduce inflammation in the body. Staying hydrated and limiting processed foods and excess alcohol supports your immune system's day-to-day function.

When will I get my results?

Results for this genetic test are typically ready within about 7 days of your sample being processed at the lab. This slightly longer turnaround is normal for high-resolution genetic typing, which requires more detailed lab analysis than a standard blood test. You'll get a notification as soon as your results are posted to your account.

Who should consider this test?

This test is a good fit if you have a family history of autoimmune conditions, are experiencing symptoms like joint pain or eye inflammation without a clear cause, or need to check for genetic risk before starting a new medication. It's also useful for people wanting more insight into inherited health risks. If any of these apply to you, this test can provide valuable, permanent genetic information.

What symptoms indicate I may need this test?

Common symptoms that lead people to this test include ongoing joint pain and stiffness, eye redness or inflammation, lower back pain that doesn't improve, or skin rashes with an unclear cause. Family history of autoimmune disease is another common reason people seek this test even without symptoms. If you've noticed these patterns, this test can help clarify whether a genetic factor is involved.

What is HLA-B and why does it matter?

HLA-B is one of many genes that help your immune system tell the difference between your own cells and harmful invaders like viruses. Certain versions, or types, of this gene are strongly associated with specific autoimmune conditions and with the way your body may react to certain medications. Understanding your specific HLA-B type gives useful, lifelong information about these risks.

What does a positive HLA-B marker result mean?

A positive result means you carry a specific genetic variation that's associated with a higher chance of developing certain autoimmune conditions or having a reaction to specific medications. It does not mean you currently have or will definitely develop the condition — it simply flags an increased genetic risk. This information is useful for guiding future health and treatment decisions with more personalized awareness.

How often should I retest?

Since HLA-B typing reflects your genetic makeup, which doesn't change over time, you typically only need to take this test once in your lifetime. There's no need for regular retesting like there is with blood chemistry panels. Keep your result saved in your account so it's available whenever it's relevant for future health decisions.
