The Carcinoembryonic Antigen (CEA) test is a blood test that helps measure the CEA protein in the blood. Abnormal levels of CEA are an indication of cancers, such as cancer of the large intestine and the rectum.
The CEA test, when conducted after the detection of cancer, helps determine the effect of the treatment. High levels of the CEA protein indicate that the cancer has not been cured and that it may have spread to other parts of the body. Doctors order this test to determine the stage of your cancer, to check the size of the tumor, and how far your cancer has spread.

The CEA test is used to study cancers of the colon, rectum, prostate, ovary, and thyroid and plan appropriate treatment. It is used to determine if your cancer is cured or has recurred. This test also helps detect if the various cancer treatments, such as chemotherapy and radiation, are being effective in treating the cancer.

Normal CEA results fall below 5 nanograms per milliliter (ng/mL).
Higher CEA results above 5 ng/mL might indicate cancer.
However, high CEA levels don’t always mean that you have cancer. Abnormal CEA levels could also be because of:
- Cirrhosis or Liver disease
- Lung problem
- Inflammatory bowel disease
- Chronic smoking
