What Does This Test Measure?

This test uses a multiplex immunoassay to detect and quantify several proteins and substances linked to ovarian cancer. These may include markers like CA-125 (a common tumor marker), but the panel also assesses additional biomarkers that may provide a more comprehensive picture of ovarian cancer presence or progression.

Why Might You Need This Test?

Your healthcare provider may recommend this test if you have symptoms suggestive of ovarian cancer (e.g., persistent bloating, pelvic pain, or unexplained weight changes), a family history of ovarian cancer, or if you are at higher risk due to other medical conditions. It may also be used during follow-up for patients already diagnosed with ovarian cancer to monitor treatment effectiveness.

How Is the Test Performed?

A blood sample is drawn from a vein in your arm. The blood is then processed and analyzed in a laboratory using a specialized immunoassay technique that detects multiple biomarkers simultaneously. Results are compared to reference ranges specific to each biomarker.

What Do the Results Mean?

Results will show the levels of each biomarker measured. Elevated levels of certain biomarkers may suggest the presence of ovarian cancer, but they are not definitive on their own. Your healthcare provider will interpret the results in the context of your symptoms, medical history, and other diagnostic tests.

Frequently asked questions

What are the most common biomarkers tested in this panel?
This panel typically includes a combination of tumor markers such as CA-125, CA125 variants, and other ovarian cancer-specific biomarkers. The exact biomarkers may vary depending on the laboratory’s protocol and your healthcare provider’s specific needs.
Can this test replace a pelvic exam or ultrasound?
No, this test is not a replacement for pelvic exams or ultrasounds. It is used alongside other diagnostic tools to help assess risk or monitor disease. Your healthcare provider will determine the best diagnostic approach based on your individual situation.
How soon will I get my results?
Results are typically available within 2–5 business days, depending on the laboratory’s processing time. Your healthcare provider will discuss the results with you and explain next steps.
