What's this test for?

This test is ideal if you or someone you're caring for has been diagnosed with a specific tumor type and needs to find out whether immunotherapy with KEYTRUDA (Pembrolizumab) could be an option. It looks at a tissue sample to see how much of a protein called PD-L1 is present on tumor cells. Knowing this helps guide treatment planning for certain approved cancer types.

What happens after I get my results?

Your results will be available in your account, with the PD-L1 expression level and what it means clearly explained. Since this is a tumor tissue test tied to treatment decisions, the main next step is reviewing the report to understand your PD-L1 status and discussing timing of any further tissue-based testing if your cancer care plan changes. The standard lab report can be downloaded directly from your account for your records. You can also track results over time using the trends feature if repeat testing is ever needed.

What's included in this test?

This test measures PD-L1 (Programmed Death-Ligand 1) protein expression on tumor cells using the IHC 22C3 pharmDx staining method applied to a tissue sample. This focused result matters because it's an FDA-approved way to help identify whether certain tumor types are more likely to respond to Pembrolizumab-based immunotherapy, giving important guidance for treatment decisions.

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

While no natural remedy replaces targeted cancer treatment, everyday habits can help support your body's overall resilience. Eating a balanced diet with plenty of protein, fruits, and vegetables helps maintain strength during treatment. Regular light activity, adequate sleep, and stress-reduction practices like meditation may also help you feel better day to day. Always coordinate any new supplement or diet changes with your treatment plan.

When will I get my results?

Results are typically ready within about 7 days after your tissue sample is processed at the lab. This timeframe allows for the specialized staining and pathology review needed for an accurate PD-L1 reading. You'll receive a notification as soon as your results are posted to your account.

Who should consider this test?

This test is intended for people with an FDA-approved tumor type who are being considered for Pembrolizumab (KEYTRUDA) immunotherapy. It's typically ordered when a tissue sample is already available for testing. If your tumor type isn't covered by this specific approved test, a broader PD-L1 IHC test with interpretation may be more appropriate.

What symptoms indicate I may need this test?

This isn't a symptom-based test — it's used after a cancer diagnosis to help plan treatment, not to detect new symptoms. If you've already been diagnosed with an eligible tumor type and are exploring immunotherapy options, this test provides useful information for that specific next step. It does not screen for cancer or diagnose new symptoms.

What is PD-L1 and why does it matter?

PD-L1 is a protein some tumor cells use to hide from your immune system, essentially telling immune cells not to attack. When tumors have high levels of PD-L1, they may respond better to immunotherapy drugs like Pembrolizumab, which block this hiding signal. Measuring PD-L1 helps show whether this type of treatment is likely to be a good fit.

What does a high PD-L1 result mean?

A higher PD-L1 expression level generally means the tumor is showing more of this protein, which can make it a stronger candidate for Pembrolizumab-based immunotherapy. This doesn't guarantee a treatment response, but it's one of the key pieces of information used in eligibility decisions. Your full report will explain the specific scoring used for your tumor type.

What should I do if my results are unclear or borderline?

If your PD-L1 result falls into a borderline range, it may be worth discussing whether additional or repeat tissue testing makes sense, especially if a new sample becomes available. Keeping a copy of your report and tracking any future results over time can help clarify patterns. If you have concerns about what a borderline result means for your specific tumor type, seek guidance promptly given the time-sensitive nature of treatment planning.
