Use

Measurement of CEA has been shown to be clinically relevant in the management of patients with colorectal, breast, lung, prostatic, pancreatic, and ovarian carcinomas. CEA levels can assist in monitoring disease progression or response to therapy. It is important to note that smokers may exhibit slightly elevated levels of CEA. However, the CEA assay value, irrespective of the level, should not be taken as evidence for the presence or absence of malignant disease and is not recommended for use as a screening test for detecting cancer in the general population.
