What's this test for?

This test is ideal if you're having a tissue sample evaluated for suspected melanoma, a serious type of skin cancer. It helps identify whether cells in a biopsy sample are melanoma cells by looking for a specific marker called MITF-1. This test is typically ordered as part of a broader diagnostic workup when there's a concerning skin lesion or growth.

What's included in this test?

This test uses a lab technique called immunohistochemistry (IHC) to detect the MITF-1 protein in a tissue sample. MITF-1 is a marker that helps pathologists identify pigment-producing cells, which is especially useful for confirming or ruling out melanoma. The result comes with an expert interpretation to help make sense of what was found in the sample.

What happens after I get my results?

Your results will appear in your account along with an interpretation explaining what the findings mean. Because this is a specialized tissue test used to help identify melanoma, next steps often involve further diagnostic follow-up depending on the interpretation provided. The full pathology report is downloadable from your account at any time, and you can revisit or reference it later using the trends feature to keep a record of your testing history.

How can I naturally support healthy skin and reduce cancer risk?

While this test itself isn't about lifestyle changes, general skin health habits can help lower your risk of skin cancer. Limiting sun exposure, wearing sunscreen daily, avoiding tanning beds, and checking your skin regularly for new or changing moles are all simple, effective habits. Eating a diet rich in antioxidants, like colorful fruits and vegetables, can also support your skin's natural defenses.

When will I get my results?

Results for this test are typically available within about 7 days after your sample is processed at the lab. Because this involves specialized tissue analysis, it can take a bit longer than a standard blood test. You'll receive a notification as soon as your results are ready to view in your account.

Who should consider this test?

This test is generally considered when someone has a suspicious skin lesion, mole, or growth that needs further evaluation for melanoma. It's often used as a follow-up after an initial biopsy shows unclear or concerning results. People with a personal or family history of melanoma may also have this type of testing done as part of a diagnostic process.

What symptoms indicate I may need this test?

Signs that might lead to this type of testing include a mole that has changed in size, shape, or color, a new dark spot on the skin, or a sore that doesn't heal. Itching, bleeding, or irregular borders on a skin growth are also common reasons a sample gets sent for this kind of analysis. If you've noticed any of these changes, it's worth getting evaluated as soon as possible.

What is MITF-1 and why does it matter?

MITF-1 stands for Microphthalmia-associated Transcription Factor, a protein that plays a key role in the development of pigment cells called melanocytes. It matters because melanoma, a dangerous skin cancer, often develops from these same pigment cells, and MITF-1 is frequently present in melanoma tumors. Detecting this marker helps confirm whether abnormal cells found in a biopsy are melanoma-related.

What does a positive MITF-1 result mean?

A positive result means the marker was detected in the tissue sample, which supports a diagnosis of melanoma or a related pigment-cell tumor. This finding is usually considered alongside other test results and the overall appearance of the tissue sample. If your result comes back positive, prompt follow-up care is important to determine the next steps.

What should I do if my results are abnormal?

If your results show signs consistent with melanoma, it's important to seek follow-up care quickly so the finding can be fully evaluated and any necessary treatment can begin. Keep a copy of your downloadable report handy, as it may be needed for further testing or evaluation. Acting quickly on abnormal skin findings can make a meaningful difference in outcomes.
