- The carcinoembryonic antigen (CEA) test measures the amount of this protein that may appear in the blood of some people who have certain kinds of cancers, especially cancer of the large intestine (colon and rectal cancer). It may also be present in people with cancer of the pancreas, breast, ovary, or lung.

Carcinoembryonic Antigen (CEA) Carcinoembryonic antigen (CEA) is a protein that is present in certain tissues of a developing baby (fetus). By the time a baby is born, it drops to a very low level. In adults, CEA is normally present at very low levels in the blood but may be elevated with certain types of cancer.

Useful For CEA : Carcinoembryonic antigen (CEA) is a glycoprotein normally found in embryonic entodermal epithelium. Increased levels may be found in patients with primary colorectal cancer or other malignancies including medullary thyroid carcinoma and breast, gastrointestinal tract, liver, lung, ovarian, pancreatic, and prostatic cancers.

Useful For Interpretation Provides information to assist in interpretation of the test results. After removal of a colorectal tumor, the serum CEA concentration should return to normal by 6 weeks, unless there is residual tumor. Increases in test values over time in a patient with a history of cancer suggest tumor recurrence.

What is cea test normal range? CEA is a protein marker indicative of several types of cancers, especially colon cancer. The CEA normal levels are different for smokers and nonsmokers. Usually, for adult nonsmokers, the normal CEA levels range from 0 to 2.5 mcg/l.For adult smokers, the levels are slightly higher, and normal levels range from 0 to 5.0 mcg/l. This difference in normal values is because smokers usually produce more CEA than nonsmokers.he CEA normal levels are different for smokers and nonsmokers. Usually, for adult nonsmokers, the normal CEA levels range from 0 to 2.5 mcg/l. For adult smokers, the levels are slightly higher, and normal levels range from 0 to 5.0 mcg/l.

Carcinoembryonic Antigen (CEA) Detected Using Blood Test The presence of certain cancers can be confirmed by the specific proteins being shed into the blood. These proteins are the tumor markers. Carcinoembryonic antigen (CEA) is the protein linked to colorectal cancers. Every one of us has a little CEA in our blood. The presence of this protein in the blood alone does not mean you have colon cancer. The CEA blood test cannot be used to diagnose cancer, only to track cancer after a diagnosis.

Carcinoembryonic Antigen Test (CEA) Carcinoembryonic Antigen Test (CEA). A carcinoembryonic antigen (CEA) test is a blood test used to help diagnose and manage certain types of cancers, especially cancer of the colon.The test measures the amount of CEA present in the blood. If you already have cancer, this test helps a doctor determine if the treatment for the cancer is working.An antigen is a harmful substance that is released by cancerous tumors. CEA test is most useful to monitor patients who already have been diagnosed with a type of cancer that is known to produce CEA. Not all cancers produce CEA. Increased levels of CEA may be found in the following cancers: 1  colorectal (colon) cancer. 2  medullary thyroid carcinoma.

The Sol Goldman Pancreatic Cancer Research Center CEA (carcinoembryonic antigen) and Ca 19-9 (Carbohydrate antigen 19-9) are two blood tests commonly used to follow patients with known cancers. CEA is a glycoprotein (sugar protein) present in embryonic tissues and in extracts from normal colonic washings.CA 19-9 is a modified blood group antigen (Lewis(a)).Neither test should be used as a cancer screening test of asymptomatic individuals.Although CEA and/or levels are often elevated in patients with gastrointestinal malignancies (colon, pancreas, etc), patients with confirmed cancers frequently have normal levels (in the range of healthy individuals).either test should be used as a cancer screening test of asymptomatic individuals. Although CEA and/or levels are often elevated in patients with gastrointestinal malignancies (colon, pancreas, etc), patients with confirmed cancers frequently have normal levels (in the range of healthy individuals).

Tumor Markers; AFP, HCG, CA-125 Tumor marker, CEA: Carcinoembryonic antigen (CEA) is a protein found in many types of cells but associated with tumors and the developing fetus. CEA is tested in blood. The normal range is <2.5 ng/ml in an adult non-smoker and <5.0 ng/ml in a smoker.

What is cea test normal range? The CEA blood test normal range is from 0 to 2.5 micrograms per liter. In people who smoke regularly, this normal range is slightly increased. For them, the CEA blood test range is 0 to 5 micrograms per liter. Values slightly higher than this are accepted as normal.

- How is it used? The blood test for aspartate aminotransferase (AST) is usually used to detect liver damage. It is often ordered in conjunction with another liver enzyme, alanine aminotransferase (ALT), or as part of a liver panel or comprehensive metabolic panel (CMP) to screen for and/or help diagnose liver disorders.

CEA Monitoring in Colorectal Cancer CEA has been studied extensively as a marker for disease recurrence in patients undergoing curative intent resection of a colorectal cancer primary. Specificity and sensitivity in detecting disease recurrence depends largely on the definition of abnormal CEA levels (cutoff CEA).

Carcinoembryonic Antigen (CEA) Most normal persons have detectable concentrations of circulating CEA. Approximately 85% of adults have CEA levels less than 2.5 ng/mL, while 95% have levels less than 5.0 ng/mL. CEA levels are slightly higher in men than women.

What is cea test normal range? It is due to this reason that this test is not used to screen for cancers. The CEA blood test normal range is from 0 to 2.5 micrograms per liter. In people who smoke regularly, this normal range is slightly increased. For them, the CEA blood test range is 0 to 5 micrograms per liter. Values slightly higher than this are accepted as normal.

Lab tests for colorectal cancer Tumor marker tests: This blood test may be used in addition to other tests for patients who are being treated for colorectal cancer. Tumor marker tests are used to check for two substances in the blood that colorectal cancer may produce: carcinoembryonic antigen (CEA) and CA 19-9.

- The uric acid blood test is used to detect high levels of this compound in the blood in order to help diagnose gout. The test is also used to monitor uric acid levels in people undergoing chemotherapy or radiation treatment for cancer. Rapid cell turnover from such treatment can result in an increased uric acid level.
