About this test

CEA rises in colorectal and several other cancers, but also in smokers and in benign bowel and liver disease, so it is a poor screening test in someone with no diagnosis. Its real value is the trend after treatment, where a rising level prompts a search for recurrence.

What it measures

  • Serum carcinoembryonic antigen

A note on results. A single test is one part of a clinical picture, not a diagnosis. Discuss your report with a qualified doctor, who will read it alongside your history and examination.
