CEA is a protein that can rise with some tumours, and also with smoking and inflammation of the bowel or liver.
It is not a screening test on its own; its main value is follow-up after diagnosis and treatment.
Preparation before the test
- No fasting needed; it can be done any time.
- Tell the lab if you smoke.
