Carcinoembryonic antigen blood test

Normal Reference Range

<5 µg/L

Test Information

Although CEA was formerly thought to only be elevated in digestive tract malignancies, it can also be elevated in some non-cancerous diseases and other tumours. Testing for CEA may be very advantageous for patients being watched for colorectal, stomach, breast, lung, prostatic, pancreatic, or ovarian cancer. In benign conditions, such as uremic colitis, cirrhosis, pancreatitis, and heavy smokers, a high CEA may be observed.

Clinical Indications

An increase in CEA after therapy is very symptomatic of a hidden metastatic and/or recurrent illness.
