CA-125

The CA-125 test measures the level of cancer antigen 125 in the blood, which is a protein produced by certain types of cancer cells, particularly ovarian cancer cells. This test is used to diagnose and monitor ovarian cancer, assess the effectiveness of treatment, and detect recurrences. Elevated CA-125 levels can indicate the presence of ovarian cancer or other conditions, such as endometriosis, pelvic inflammatory disease, and liver disease. The CA-125 test is valuable for guiding treatment decisions, evaluating therapy outcomes, and monitoring for cancer recurrence in patients with ovarian cancer.
