Hello and thank you for asking

There is a correlation between smoking and elevated CEA levels. Smoking reduces the ability of the immune system to produce the antibodies needed to fight off antigens .Serum CEA levels rise with each cigarette smoked.

In my opinion you should repeat your test after 1-2 months.
If you have diarrhea how has not been diagnosed than a colonoscopy will help

Best regards
