The CA 72-4 test is a blood-based tumor marker assay primarily used to aid in the detection and management of certain cancers, particularly gastric, pancreatic, and ovarian cancers. It measures the concentration of the CA 72-4 antigen, a high molecular weight glycoprotein present on the surface of malignant cells. While elevated levels may suggest tumor presence, the test is not diagnostic on its own and should be interpreted alongside imaging studies, clinical evaluation, and other tumor markers such as CEA or CA 19-9. CA 72-4 is also useful for monitoring treatment response and detecting recurrence, as decreasing levels may indicate therapeutic effectiveness, whereas rising levels can signal disease progression. False positives can occur in benign conditions like gastritis, liver disease, or endometriosis, emphasizing careful interpretation.
