Carcino Embryonic Antigen

Carcino Embryonic Antigen


The CEA blood test measures the amount of carcinoembryonic antigen (CEA) in your bloodstream. CEA is a tumour marker that may be raised in some cancers, particularly colorectal cancer, as well as in certain non-cancerous conditions such as inflammation or liver disease. This test is most often used to monitor cancer treatment effectiveness or to detect recurrence after treatment. It is not typically used as a standalone diagnostic test but as part of a broader clinical assessment.
