What's this test for?

This test is ideal if you're navigating a cancer diagnosis and you or your care team are exploring whether immunotherapy could be an effective treatment option. It looks at whether your tumor tissue expresses a specific protein called PD-L1, which can influence how certain cancer treatments work. This test is typically used alongside other diagnostic information as part of a broader treatment planning process.

What happens after I get my results?

Your results will be available in your account, and the report explains what the finding means along with the relevant reference information. Because this is a specialized tumor marker test, the actionable next step is usually to bring the report into your treatment planning discussions so it can be considered alongside your other diagnostic information. A standard lab report is available for download from your account at any time. You can also track this and any future related results over time using the trends feature.

What's included in this test?

This test includes PD-L1 immunohistochemistry (IHC) analysis with expert pathology interpretation, evaluating PD-L1 protein expression directly in a sample of tumor tissue using a specialized staining technique. Understanding whether your tumor expresses this protein matters because it can indicate how your immune system is interacting with cancer cells and whether certain immunotherapy drugs are more or less likely to be effective.

How can I naturally support my immune system during cancer treatment?

While no natural remedy replaces medical treatment, some everyday habits can support your body's overall resilience. Eating a balanced diet with plenty of fruits, vegetables, and lean protein helps maintain strength and energy during treatment. Regular light activity, adequate sleep, and stress-reduction practices like meditation or gentle walks can also help your body cope better. Always pair these habits with the treatment plan you and your care team have developed.

When will I get my results?

Results for this PD-L1 test are typically ready within about 7 days after your sample is processed at the lab. This timeframe allows for the detailed tissue staining and interpretation process required for accurate results. You'll receive a notification as soon as your report is ready to view in your account.

Who should consider this test?

This test is generally considered by individuals who have already been diagnosed with a solid tumor cancer and are evaluating treatment pathways that include immunotherapy. It's also relevant if you're researching second-line treatment options after an initial therapy hasn't worked as hoped. This test is a good next step when immunotherapy is being actively discussed as a possible treatment route.

What symptoms indicate I may need this test?

This test isn't typically ordered based on symptoms alone — it's used after an existing cancer diagnosis to help guide treatment decisions. If you've noticed new or worsening symptoms related to a known tumor, such as unexplained pain, fatigue, or changes in a previously diagnosed area, it's worth discussing whether this type of tissue testing fits your situation. The test itself doesn't diagnose cancer; it characterizes tumor tissue that has already been identified.

What is PD-L1 and why does it matter?

PD-L1 is a protein that some cancer cells use to hide from your immune system, essentially telling your immune cells to stand down. When a tumor expresses high levels of PD-L1, certain immunotherapy drugs designed to block this protein may be more effective at helping your immune system recognize and attack the cancer. This makes PD-L1 testing an important piece of information for personalizing treatment approaches.

What does a high PD-L1 result mean?

A high or 'positive' PD-L1 result means your tumor cells are expressing significant amounts of this protein, which can suggest your cancer may respond well to PD-1/PD-L1 targeting immunotherapy drugs. This is generally seen as useful information for expanding treatment options. It doesn't guarantee a specific outcome, but it's a meaningful data point in your overall treatment picture.

How often should I retest?

PD-L1 expression is typically tested once on an existing tumor sample rather than on a recurring schedule, since it's tied to treatment planning rather than routine monitoring. However, if you develop a new tumor, experience disease progression, or your treatment plan changes significantly, retesting a new tissue sample may be worthwhile. This helps ensure treatment decisions are based on the most current information about your tumor's biology.
