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, it's important to check for hidden infections like hepatitis B, hepatitis C, and latent tuberculosis. These infections often show no symptoms but can become active and dangerous once the immune system is suppressed by biologic therapy.

How should I prepare for this test?

How can I naturally support my immune system before starting biologic therapy? While this panel itself requires no special preparation, supporting your overall immune health beforehand can help your body handle treatment better. Getting enough sleep, eating a balanced diet rich in vitamins C and D, staying hydrated, and avoiding alcohol can all help keep your immune system functioning well. Avoiding close contact with anyone who has an active respiratory illness is especially helpful before a TB screening.

What's included in this test?

This panel checks for three types of hidden infections that could become dangerous once immune-suppressing therapy begins: hepatitis C, hepatitis B, and latent tuberculosis. Each of these infections can stay silent for years but flare up when the immune system is weakened, so catching them beforehand helps avoid serious complications. Reflex testing is included, meaning if an initial screen suggests infection, additional confirmatory tests are automatically run on the same sample.

What happens after I get my results?

Your results will be available in your account, with each value's normal range clearly explained so you know exactly where you stand. If any screening comes back positive or indeterminate, the report will flag it so you understand which values need a closer look before starting biologic therapy. You can download a standard lab report from your account at any time, and if you're retested in the future, you can track your results over time using the trends feature. If any result suggests an active infection, seek medical care promptly since this can affect the timing of your treatment.

When will I get my results?

Results for this panel are typically ready within about 7 days. This timeline allows for the necessary lab processing of all three screenings, including any reflex testing that may be needed based on initial results. You'll receive a notification when your results are ready to view in your account.

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 useful for anyone who has been told by their treatment plan that pre-therapy infection screening is required. Getting this done early helps avoid delays in starting your treatment.

What symptoms indicate I may need this test?

Latent infections like hepatitis B, hepatitis C, and TB often cause no symptoms at all, which is exactly why screening matters before starting biologic therapy. You might not feel sick even though one of these infections is present in your body. If you've been diagnosed with an autoimmune condition and your treatment plan includes a biologic medication, that alone is the signal to get screened, regardless of how you feel.

What does a positive hepatitis or TB result mean?

A positive result on any part of this panel means the reflex testing will run automatically to confirm whether the infection is active, past, or latent. This doesn't necessarily mean you can't proceed with biologic therapy, but it does mean additional monitoring or treatment for the infection may need to happen first. Your lab report will explain what the specific result means in plain terms.

How often should I retest?

Typically, this screening is done once before starting a new biologic or biosimilar medication, since that's the window when hidden infections pose the greatest risk. If your treatment is paused and restarted later, or if you switch to a different biologic after a long gap, retesting may be recommended again. Check your treatment timeline to see if a repeat screen makes sense.

What should I do if my results are abnormal?

If any part of this panel comes back positive, don't start your biologic medication until the situation is fully understood, since immunosuppression can allow a hidden infection to become active and serious. Review the detailed explanation in your report, which breaks down what the specific finding means. If your result indicates an active infection, seek medical care right away so it can be properly managed before your treatment begins.
