CEA Test

The cea blood test kit is used to determine the content of Carcinoembryonic antigen (CEA) in human serum to be used as an aid in the prognosis and management of cancer patients in whom changing concentrations of CEA are observed.

Testing Principle of CEA Test

  • Carcinoembryonic antigen (CEA), first described in 1965 by Gold is a tumor-associated antigen.

  • With a molecular weight of 180-200 kDa.

  • CEA is present in high concentrations during fetal development but ceases after birth.

  • Therefore, it is not usually present in the blood of healthy adults.

  • The normal CEA range for a nonsmoking adult is less than 2.5 ng/mL and less than 5.0 ng/mL in a smoker.

  • Additional studies have also shown that increased CEA levels are also found in patients with other types of carcinomas such as breast, lung, genitourinary tract, and lymphoid tissue.

  • Benign conditions that can also cause significantly higher than normal CEA levels include inflammation of the lung and gastrointestinal (GI) tract and benign liver cancer.

  • In colorectal cancer, the clinical use of CEA testing is for monitoring response to therapy and for documenting the progression of the disease.
