Quick answer
The CA-125 test measures the amount of cancer antigen 125 in the blood. CA-125 is a protein that can be elevated in ovarian cancer and in several non-cancerous conditions. It is most useful for monitoring a known cancer or supporting an evaluation when symptoms or imaging raise concern, rather than as a routine screening test for everyone.
What this test measures
Cancer antigen 125 is a protein found on the surface of many ovarian cancer cells, and it can also be produced by other tissues. Its level is measured in a blood sample. Because CA-125 can rise for reasons unrelated to cancer, including menstruation, endometriosis, pregnancy, and liver or pelvic inflammation, the result is never interpreted on its own.
The test uses a blood sample drawn from a vein. Results are reported as a concentration, and clinicians compare the value with a reference range while considering the person's age, symptoms, and imaging findings. In people with a known ovarian cancer, serial CA-125 measurements can help show how the disease is responding to treatment.
CA-125 is not recommended as a general screening test for ovarian cancer in people without symptoms, because a normal result does not rule out disease and an elevated result often has a benign explanation. It is best used as one part of a broader assessment, and a qualified healthcare provider decides how the result fits into the overall picture.
