what is cea?
CEA short for Carcinoembryonic Antigen, is a glycoprotein by the cells of the gastrointestinal tract during foetus development. It is found on the surface of certain cells . CEA is formed in the gastrointestinal tissue during pregnancy, and stops before child birth and that’s why CEA is found in extremely low levels in the blood of healthy adults. However, elevated CEA levels are common in heavy smokers and people suffering from certain types of cancer, and as such Carcinoembryonic Antigen is used as a tumour marker in clinical tests.

Even heavy smokers have elevated CEA levels, yet it is less than 5 ng/ml. A CEA level higher than 20 ng/ml is extremely high and is in all probability a a sign of cancer.
