Choosing Clinical Laboratory Tests Wisely Guidelines:
CEA is elevated in patients with a wide range of malignancies including colorectal, gastric, pancreatic, lung, breast, and medullary thyroid cancer. It is also elevated in non-malignant disorders; ulcerative colitis, pancreatitis, cirrhosis, pleural inflammation, chronic renal failure and in smokers. It is most widely used in monitoring colorectal cancer (CRC) but is not sufficiently sensitive to be used in screening.
CEA testing is indicated in/for:
0.3 mL serum or heparin plasma
