    What is Carcinoembryonic Antigen (CEA) Test?

    The Carcinoembryonic Antigen (CEA) test measures CEA levels in the blood.

    CEA, a glycoprotein, is produced by both normal and cancerous cells. It was first discovered in 1968 in liver cells affected by colorectal cancer and in foetal digestive cells. While CEA is elevated at birth and generally decreases with age, certain medical conditions, including cancers, can cause CEA levels to rise.

    Most CEA tests are conducted using blood samples, but in rare cases, fluids from the spine, chest, or abdomen may be used. For individuals diagnosed with cancer, particularly colorectal cancer, CEA testing helps monitor treatment response, track relapses, and identify recurrences.

    CEA testing is also beneficial for monitoring cancers of the breast, lung, ovaries, bladder, and thyroid. To fully assess a patient’s health and response to treatment, CEA levels are often combined with physical exams, imaging scans, and other lab tests.

    Carcinoembryonic Antigen (CEA) Test Parameters

    The Carcinoembryonic Antigen test measures one parameter: the level of CEA in the blood.

    CEA is a glycoprotein produced by both normal and cancerous cells. First identified in 1968 from liver cells affected by colorectal cancer and from foetal digestive cells, CEA is naturally high at birth and typically decreases with age. However, some medical conditions, including certain cancers, can cause an increase in CEA levels.

    Most CEA tests are done on a blood sample to measure CEA levels. In rare cases, samples may also be taken from fluid in the spine, chest, or abdomen if needed. For patients diagnosed with cancers, especially colorectal cancer, CEA testing assists in monitoring treatment response, tracking for relapses, and detecting recurrences.

    Beyond colorectal cancer, CEA testing can also support monitoring in cases of breast, lung, ovarian, bladder, and thyroid cancers. To get a complete understanding of a patient’s health and response to treatment, CEA levels are generally assessed alongside imaging scans, physical exams, and additional lab tests.

    Carcinoembryonic Antigen (CEA) Test Preparation

    Here are a few things to consider before scheduling a Carcinoembryonic Antigen test in Delhi:

    • Prerequisites

    • Fasting is not required before undergoing a Carcinoembryonic Antigen test.

    • Best Time to Get Tested

    This test can be scheduled at any time during the day.

    • Who Should Get This Test

    It is recommended for individuals diagnosed with cancers, primarily colorectal cancer, to monitor their treatment response, check for potential relapses, and detect recurrences.

    • Cautions Before Taking This Test

    Typically, no special preparation is necessary, but consult your doctor for specific guidance prior to the test.

    Why Take the Carcinoembryonic Antigen (CEA) Test?

    While the CEA test can help diagnose cancer when used with other tests and provide important information for those already diagnosed, it is not used alone for cancer diagnosis. This test is typically recommended for:

    • Checking cancer spread : It can help determine if cancer has spread or grown to other parts of your body.

    • Evaluating treatment success : It indicates how well your cancer treatment is working.

    The test may be conducted at different stages, such as:

    • Right after diagnosis : To assist in developing an appropriate treatment plan.

    • During treatment : To assess the effectiveness of therapies such as chemotherapy, immunotherapy, or radiation.

    • After treatment : To check for any signs of recurrence.

    • Before starting treatment or surgery : Regular follow-up testing is typically done every one to three months during active treatment.

    It’s important to understand that a rise in CEA levels four to six weeks after starting treatment doesn't automatically suggest that treatment is not working. If you're in remission, your doctor may recommend regular CEA tests to monitor for recurrence, and they will decide on the frequency.
