Hi,
Thanks for writing in.

The normal value of CEA is less than 3 in healthy non smokers. It can indicate cancer of bowel, pancreas, ovary, breast, liver and lung among many others. However it does not always indicated cancer in a person without symptoms.

The concentration of carcinoembryonic antigen (CEA) in serum should not be used to screen asymptomatic individuals for neoplastic disease, and the diagnostic efficacy of CEA measurements in high-risk groups has not been established.

Single values of CEA are less informative than changes assessed over time. Please discuss with your doctor and get the test repeated after a few weeks and to check if it is a concern. Please do not worry.
