    What is Carcinoembryonic Antigen (CEA) Test?

    The CEA test measures carcinoembryonic antigen, or CEA, in the blood. CEA, a tumor marker, is a protein produced by certain cancer cells. Although healthy cells produce small quantities of CEA, many people maintain CEA levels within a “normal range,” often shown as the reference range on lab reports.

    This test can help in identifying certain cancers, as high CEA levels may indicate cancers of the colon, rectum, lungs, liver, breast, pancreas, prostate, thyroid, and ovaries. For patients with an existing diagnosis, CEA levels checked over time may provide information on cancer status, recovery chances, or recurrence risks. Doctors may also monitor CEA to assess treatment effectiveness.

    It’s essential to remember that the CEA test alone isn’t a definitive cancer diagnostic tool. Some individuals with cancer can have a normal CEA reading, while some non-cancer conditions like liver, digestive, or respiratory issues may cause higher CEA levels. Thus, CEA testing is generally used with other tests to get a clearer view of a patient’s health and treatment progress.

    Carcinoembryonic Antigen (CEA) Test Parameters

    The Carcinoembryonic Antigen (CEA) test determines the level of CEA in the blood.

    CEA is a glycoprotein secreted by both healthy and cancerous cells. It was first discovered in 1968 from liver cells affected by colorectal cancer and foetal digestive cells. While CEA levels are high at birth and naturally decrease over time, certain cancers and medical conditions can cause an increase in CEA levels.

    Typically, CEA tests are conducted on blood samples, but in rare cases, fluid samples from the spine, chest, or abdomen may also be tested. For patients with cancer, particularly colorectal cancer, CEA testing is important for monitoring treatment progress, detecting relapses, and identifying recurrences.

    It is also used to monitor breast, lung, ovarian, bladder, and thyroid cancers. For a comprehensive evaluation of a patient’s health and treatment response, CEA levels are often assessed alongside imaging, physical exams, and additional laboratory tests.

    • Best Time to Get Tested

    The test can be conducted at any point throughout the day.

    • Who Should Get This Test

    • Cautions Before Taking This Test

    While no special preparation is needed, it is important to consult your doctor before taking the test.

    Why Take the Carcinoembryonic Antigen (CEA) Test?

    The CEA test can assist in diagnosing cancer when used alongside other diagnostic methods, and it provides helpful information for individuals already diagnosed with cancer. However, it is not a diagnostic tool on its own. The test is often recommended for:

    • Checking for cancer spread : It helps determine whether cancer has spread to other parts of your body.

    • Evaluating treatment effectiveness : It allows assessment of how well cancer treatments are working.

    You may need this test at various stages, such as:

    • Immediately after diagnosis : To help plan the course of treatment.

    • During ongoing treatment : To check the effectiveness of chemotherapy, immunotherapy, or radiation.

    • After completing treatment : To monitor for any signs of cancer returning.

    • Before starting treatment or surgery : Follow-up tests are often performed every one to three months during active treatment.

    An increase in CEA levels within four to six weeks after starting treatment doesn’t always signal treatment failure. If you're in remission, your doctor might recommend regular CEA tests to watch for signs of recurrence and will decide the appropriate testing frequency.
