Who gets for testing CEA (carcinoembryonic antigen)?

Certain cancers. Cea (carcinoembryonic antigen) can be found at elevated levels in the blood of patients with certain cancers such as colon, lung, breast. It is useful to follow if elevated at the time of diagnosis to correlate with response (if it goes down) to treatment or with relapse (if it becomes elevated again after having gone down to normal levels previously). It may be elevated in other benign conditions.

What are the methods for testing CEA (carcinoembryonic antigen)?

CEA. Is a blood test. This is a test to monitor response to colon cancer treatment (is not used for screening or diagnosis- this is very important to understand). Persistet elevation after treatment signals residual disease or reocurrence. A low value does not rule out reocurrence. Smoker tend to have elevated results. Your oncologist will monitor this and follow proper oncolgy guidelines for colon ca.
CEA.. CEA. Is not used as a screening test. Only to follow a malignancy along pre/post-treatment. Its is not only for colon cancer. Many other cancers will cause its elevation. Also it is important to realize that there are other causes for CEA elevation that are not rooted in cancer.

What are the methods used for checking CEA (carcinoembryonic antigen)?

Immunoenzymatic test. A very commonly established way to check for the presence of certain proteins in the blood/serum uses a combination of monoclonal antibodies directed at one part of the CEA (carcinoembryonic antigen). One of the antibodies is linked to an enzyme which causes a chemiluminiscent reaction easily detected, the intensity of which corresponds to the amount of CEA detected.
