Test Overview
Chemiluminescent Immunoassay (CLIA)
Follow-up management of patients undergoing cancer therapy, especially for ovarian carcinoma. Consistently rising CA 125 results may be associated with malignant disease and poor response to therapy; declining values may be indicative of a favorable response to therapy.
* Reference ranges may change over time. Please refer to the original patient report when evaluating results.
CA 125 concentrations are elevated in 1-2% of healthy individuals and may be elevated in diseases other than ovarian cancer, including benign and malginant disorders. CA 125 is NOT a cancer screening test.
