The AFIAS CEA test is a fluorescence immunoassay (FIA) for the quantitative determination of carcinoembryonic antigen (CEA) in human serum or plasma. The test is used as an aid in the treatment and monitoring of cancer patients. For in vitro diagnostic use only.
Carcinoembryonic antigen (CEA) is a 180 kDa oncofetal glycoprotein that is detectable in high amounts in the foetal intestine during embryonic development and to a lesser extent in the normal adult intestinal epithelium. It occurs in very high amounts in various benign diseases and in some malignant tumours, including inflammation or tumours in the stomach, small intestine, colon, rectum, pancreas, liver, breast, ovaries, cervix and lung. In addition, CEA is produced by epithelial cells in various non-malignant diseases such as diverticulitis, pancreatitis, inflammatory bowel disease, cirrhosis, hepatitis, bronchitis and kidney failure, as well as in smokers. This fact makes it difficult to use the determination of CEA in serum as a sensitive method for tumour screening, but the measurement of serum CEA levels is useful in monitoring tumour recurrence in individuals.
