Carcinoembryonic Antigen (CEA), Serum

1 Day(s)

Reference Range

Carcinoembryonic Antigen (CEA) is a protein-polysaccharide complex present in colon carcinomas and in normal fetal intestine, pancreas, and liver. Following birth, CEA levels fall. In adults, CEA is normally present at very low levels in blood. This test is useful in monitoring the treatment of cancer patients, especially those with colon cancer, and for detecting cancer recurrence after tumor excision. HIGH levels of CEA are associated with colon carcinoma, cirrhosis, ulcerative colitis, and other types of cancer (ex. Breast, pancreas, bladder, ovary, and cervix). High levels might also be seen in heavy cigarette smoking. DECREASED levels after therapy mean that most or the entire CEA-producing tumor has been removed.
