What's this test for?

This test is ideal if you're about to start treatment with a biologic or biosimilar medication for a chronic autoimmune condition like rheumatoid arthritis, psoriasis, or inflammatory bowel disease. Before these medications can be started safely, it's important to check for hidden infections like hepatitis B, hepatitis C, and latent tuberculosis. This test helps if you have an upcoming biologic treatment plan and need this required pre-treatment clearance.

What's included in this test?

This panel checks for three infections that can become dangerous once your immune system is suppressed by biologic therapy: hepatitis C, hepatitis B, and latent tuberculosis. Each of these infections can hide in the body without symptoms, but immunosuppressive treatment can allow them to become active and cause serious illness, which is why screening beforehand matters so much.

What happens after I get my results?

Your results will show up in your account with each value explained, so you can see clearly whether any of the screened infections were detected. If everything comes back clear, you can move forward with your biologic treatment plan; if something is flagged, that infection typically needs to be addressed or monitored before starting immunosuppressive therapy. You can download a standard lab report from your account at any time, and if you ever need this screening again in the future, you can track your results over time using the trends feature.

How can I naturally support my immune system before starting treatment?

While this screening focuses on detecting infections rather than boosting immunity, general habits like getting enough sleep, eating a balanced diet, staying hydrated, and avoiding alcohol can support your overall health going into treatment. Managing stress and avoiding close contact with anyone who has an active respiratory illness can also help lower your risk of catching something new. These habits won't clear an existing infection, but they support your body as you prepare for biologic therapy.

When will I get my results?

Results for this panel are typically ready within about 7 days, since it includes several tests plus reflex testing that may run automatically if an initial result needs follow-up. You'll be notified as soon as your results are available in your account. If your treatment start date is approaching, plan to schedule this test with that turnaround time in mind.

Who should consider this test?

Anyone who has been diagnosed with a chronic autoimmune condition, such as rheumatoid arthritis, plaque psoriasis, or inflammatory bowel disease, and is preparing to start a biologic or biosimilar medication should consider this test. It's also relevant if your treatment plan requires proof of infection screening before your first dose can be approved. This applies whether it's your first biologic or you're switching to a new one.

What symptoms indicate I may need this test?

Latent infections like hepatitis B, hepatitis C, and tuberculosis often cause no symptoms at all, which is exactly why screening is required rather than optional. You generally won't feel sick from a latent infection, so the need for this test comes from your treatment plan rather than how you feel. If you do have symptoms like fatigue, unexplained weight loss, night sweats, or a persistent cough, it's especially important to get screened before starting immunosuppressive therapy.

What does a positive hepatitis or TB result mean?

A positive result means the screening detected signs of hepatitis B, hepatitis C, or tuberculosis exposure, and reflex testing may be run automatically to confirm and clarify the finding. This doesn't necessarily mean the infection is currently active, but it does mean it needs to be addressed before starting a biologic, since immunosuppressive treatment can allow a dormant infection to become active. Your report will explain what the specific result means and what type of follow-up testing or care is typically needed.

What causes hepatitis B, hepatitis C, or latent TB infections?

Hepatitis B and C are usually spread through contact with infected blood or bodily fluids, such as through shared needles, unprotected sex, or from mother to child at birth. Latent tuberculosis is spread through the air when someone with active TB coughs or sneezes, and it can stay dormant in the body for years without causing symptoms. Many people carry these infections without knowing it until they're screened, which is why this pre-treatment check is so valuable.

How often should I retest?

This screening is typically done once before starting a biologic or biosimilar for the first time. If you switch to a different biologic medication or if there's a treatment gap of a year or more, retesting is usually recommended again to confirm you're still clear. Your treatment plan will guide the exact timing, but this test isn't usually part of routine ongoing monitoring.
