CEA Most Popular

The CEA test contains 1 test with 1 biomarker.

Description: CEA is a test that measures the levels of carcinoembryonic antigens in the blood. It is used to evaluate a person who has been diagnosed with cancer. The levels of CEA maybe elevated with certain types of cancer.

Also Known As: Carcinoembryonic antigen Test

Collection Method: Blood Draw

Specimen Type: Serum

Test Preparation: No preparation required

When is a CEA test ordered?

When a person is diagnosed with colon cancer or another type of cancer, a CEA test may be ordered. It will be evaluated before treatment begins and subsequently on a frequent basis to assess treatment success and detect recurrence.

When cancer is suspected but not yet diagnosed, a CEA test may be conducted. Although CEA can be increased with a variety of illnesses, this is not a popular usage for the test, it may provide additional information to a healthcare practitioner.

When a healthcare practitioner suspects that a cancer has metastasized, a CEA test may be conducted on a fluid other than blood.

What does a CEA blood test check for?

Carcinoembryonic antigen is a protein found in the developing tissues of a fetus. It drops to a very low level by the time a baby is delivered. CEA is generally seen in extremely low amounts in the blood of people, but it can be raised in cancer patients. This test examines the quantity of CEA in the blood to aid in the evaluation of cancer patients.

CEA is a tumor indicator. CEA was once assumed to be a particular marker for colon cancer, however subsequent research has revealed that an elevation in CEA can be detected in a variety of malignancies. Non-cancer disorders such as inflammation, cirrhosis, peptic ulcer, ulcerative colitis, rectal polyps, emphysema, and benign breast disease, as well as smokers, can cause an increase in CEA. As a result, it is ineffective as a general cancer screening tool, although it does play a role in assessing cancer therapy response. An initial CEA baseline test may be performed after a person has been diagnosed with cancer. If this level is raised, serial CEA testing may be used to track the cancer's progress as the patient receives treatment.

Lab tests often ordered with a CEA test:

  • Tumor Markers
  • CSF Analysis
  • Body Fluid Analysis
  • CA 19-9
  • Calcitonin
  • Alpha Fetoprotein
  • Antiphospholipid Antibodies

Conditions where a CEA test is recommended:

  • Colon Cancer
  • Colorectal Cancer
  • Pancreatic Cancer
  • Ovarian Cancer
  • Breast Cancer
  • Thyroid Cancer
  • Lung Cancer

How does my health care provider use a CEA test?

The carcinoembryonic antigen test can be utilized in the following situations:

  • To keep track of the treatment of persons who have been diagnosed with colon cancer. It can also be used as a marker for rectum, lung, breast, liver, pancreatic, stomach, and ovary malignancies. Prior to therapy, a CEA test is usually ordered as a "baseline" measurement. If the level is high, the test can be used to track a patient's response to treatment and see if the cancer has advanced or returned.
  • Cancer staging entails determining the size of the tumor as well as the extent to which it has spread.
  • CEA testing in a bodily fluid sample can help doctors figure out if cancer has progressed to a body cavity like the chest or abdomen.
  • In the examination of cancer, a CEA test can be performed in conjunction with other tumor markers.

CEA is not produced by all malignancies, therefore a positive CEA test does not always indicate cancer.

What do my CEA test results mean?

Monitoring treatment and recurrence: CEA levels that are first raised but later return to normal following treatment indicate that the cancer has been successfully treated. The first symptom of tumor recurrence is frequently a progressively rising CEA level.

Staging: People with smaller and early-stage tumors are more likely to have a normal or slightly raised CEA score on initial testing. A high CEA value is more probable in people with larger tumors, later-stage cancer, or cancers that have disseminated throughout the body.

Testing for metastasis: If CEA is found in a bodily fluid other than blood, the cancer has most likely migrated to that part of the body. If CEA is found in CSF fluid, for example, it could suggest that cancer has spread to the central nervous system.

Because not all malignancies produce CEA, it's possible to have cancer and a normal CEA at the same time. The test will be useless as a surveillance tool if a malignancy does not produce CEA.

We advise having your results reviewed by a licensed medical healthcare professional for proper interpretation of your results.

The CEA test measures the level of carcinoembryonic antigen (CEA) in the blood. CEA is a protein normally found in the tissue of a developing baby in the womb. The blood level of this protein disappears or becomes very low after birth. In adults, an abnormal level of CEA may be a sign of cancer.
