Double reference ranges for CEA smokers and non- smokers; true or false?

Carcinoembryonic antigen (CEA) belongs to the group of carcinofetal antigens that are produced during embryonic and fetal period. CEA is found in the fetal gastrointestinal tract, in the fetal serum and in slight quantities in intestinal, pancreatic, and hepatic tissue of healthy adults (slight to moderate CEA elevations occur in benign diseases of mentioned tissues). According to literature smokers have slightly increased CEA values but high concentrations are found in colorectal adenocarcinoma.
