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. 

what is a cea blood test?

A CEA blood test is essentially a blood test that is used in the diagnosis and management of certain types of cancer. The CEA blood test assesses the amount of Carcinoembryonic Antigen in the blood.

The CEA normal range is either less than or equal to 3 nanograms per millilitre (ng/mL). Anything above 3 ng/mL is indicative of elevated CEA level. This could be due to several other reasons apart from cancer like;

  • Infection
  • Cirrhosis
  • Chronic Smoking
  • Inflammatory bowel disease

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.
