Carcinoembryonic Antigen (CEA)

The CEA Test measures the amount of carcinoembryonic antigen in the blood. CEA is a protein typically found in very low levels in healthy adults but may be produced in higher amounts by certain types of cancer cells. This test is primarily used as a "tumor marker" to monitor treatment and check for recurrence in individuals already diagnosed with cancer.
