What's this test for?

This test is ideal if you're being evaluated for a suspicious tissue growth and your care team needs to tell whether it's benign or cancerous. It's often used when there's concern about mesothelioma, uveal melanoma, or an atypical Spitz tumor. The test looks at a tissue sample to help clarify a diagnosis that can be hard to pin down with standard tissue exams alone.

What's included in this test?

This test uses a lab technique called immunohistochemistry (IHC) to check whether a protein called BAP1 is present or missing in your tissue sample. Losing BAP1 expression is a pattern seen in certain cancers, so checking for it helps pathologists tell the difference between a harmless growth and a more serious one. A written interpretation from a pathologist is included to help make sense of the finding.

What happens after I get my results?

Your results will appear in your account along with an explanation of what the finding means for the tissue sample tested. Next steps depend on the result: a loss of BAP1 expression points toward a specific diagnosis and may lead to further testing or closer monitoring, while a normal result may lower suspicion for certain cancers. You can download the full lab report directly from your account at any time, and if repeat testing is ever needed, you can track results over time using the trends feature. If your report includes any values described as urgent, seek medical care right away.

How can I naturally support healthy cell function?
While no lifestyle change can reverse a genetic change like BAP1 loss, general habits that support healthy cells include eating a diet rich in vegetables and antioxidants, avoiding tobacco, limiting excess sun and UV exposure, and managing stress well. Regular exercise and good sleep also support your body's natural cell-repair processes. These habits won't replace medical follow-up but can support your overall health while you await results.
When will I get my results?
Results are typically ready within about 7 days after your tissue sample is processed at the lab. This turnaround allows time for the specialized staining and pathologist interpretation that this test requires. You'll receive a notification as soon as your report is available in your account.
Who should consider this test?
This test is a good fit for people who have had a biopsy of a suspicious growth — especially one suspected to be mesothelioma, a Spitz-type skin lesion, or a uveal (eye) melanoma — and need extra clarity beyond a routine tissue exam. It's also useful for people with a personal or family history of BAP1-related tumor syndrome. This test is a good next step when your biopsy findings alone aren't conclusive.
What symptoms indicate I may need this test?
You might consider this test if you have an unusual, changing, or fast-growing skin lesion, a persistent chest or abdominal mass, or vision changes linked to a suspicious eye growth. Unexplained symptoms like persistent chest pain, shortness of breath, or fluid buildup around the lungs can also prompt this kind of testing when mesothelioma is suspected. Any biopsy result that comes back unclear or atypical is another common reason this test gets ordered.
What does a loss of BAP1 expression mean?
When BAP1 expression is lost in a tissue sample, it means the cells are missing a protein that normally helps control cell growth and repair DNA damage. This pattern is commonly seen in malignant mesothelioma, uveal melanoma, and some atypical Spitz tumors, so it raises suspicion for one of these conditions. Losing BAP1 does not confirm cancer on its own — the pathologist interprets it alongside the rest of your tissue findings.
What causes loss of BAP1 expression?
BAP1 loss can happen because of an inherited genetic mutation passed down in families (BAP1 tumor predisposition syndrome) or because of a mutation that occurs only in the tumor cells themselves, unrelated to family history. Environmental exposures like asbestos are strongly linked to BAP1 loss in mesothelioma cases specifically. Genetic counseling can help clarify whether an inherited cause is involved.
What should I do if my results show BAP1 loss?
If your report shows a loss of BAP1 expression, the most important step is discussing the finding with your care team so it can be viewed alongside your full clinical picture. This finding often supports a specific diagnosis and may lead to additional imaging, staging tests, or genetic counseling if a hereditary link is suspected. Keeping a copy of your report and tracking any follow-up testing over time can help keep your care organized.

BAP1 Protein Expression Loss of Expression
Demo results
Retained (Normal) Loss of Expression (Abnormal)
Loss of Expression

What this means

A 'Loss of Expression' result means the BAP1 protein was not detected in the tissue sample, a pattern often seen in malignant mesothelioma, uveal melanoma, and some atypical Spitz tumors. A 'Retained' result means the protein was present, which is more typical of benign tissue. This finding is interpreted alongside the rest of your tissue exam, not on its own.

* Regular blood test results (e.g., CBC) typically start arriving the next business day after sample collection. More advanced tests may take longer due to complexity.
