Tumor Markers for Gastrointestinal Cancers What This Means for Patients. For patients with stage II or III colorectal cancer, CEA testing after surgery is recommended every three months, for at least three years after diagnosis. Along with other tests, CEA tests are one way doctors can find out whether the cancer has spread or returned.

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.

Carcinoembryonic Antigen Level or CEA Tests Carcinoembryonic antigen colon cancer and rectal cancer is one of the most common types of cancers that cause an increase in CEA levels. Both malignant and benign cancers can increase the CEA levels.

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.

- The best use of CEA is as a tumor marker, especially for cancers of the gastrointestinal tract. When the CEA level is abnormally high before surgery or other treatment, it is expected to fall to normal following successful surgery to remove all of the cancer.EA is a type of glycoprotein molecule that is produced by cells of the gastrointestinal tract during embryonic development. It is produced in very small amounts after birth. The level of CEA in the bloodstream is thus relatively low unless certain diseases-including certain forms of cancer-are present.

Tumor Markers Clinical Background. CEA is an oncofetal glycoprotein present in the gastrointestinal tract and body fluids of the embryo and fetus. This 180-kilodalton antigen is also present in certain adult gastrointestinal cells, including the mucosal cells of the colorectum, and small amounts are present in blood.

Carcinoembryonic Antigen Test (CEA) The CEA test is used especially for cancers of the large intestine and rectum. You doctor can also use the test results to help determine if a cancer treatment is working. An antigen is a substance that’s made by cancerous tumor cells. Sometimes antigens are released into the bloodstream.

Cancer Antigen 19-9 Laboratories may use different methods to test for CEA, so results can vary from lab to lab. If you are having a series of CEA tests done, it is advised that you have the tests done by the same method, typically by the same laboratory, so that the results can be compared and interpreted correctly.

National Leader in Affordable Direct to Consumer Lab Testing Specimen Type: Blood. Description: This test measures the level of Carcinoembryonic Antigen (CEA) in the blood. CEA is a protein which is often elevated in people with certain types of cancer. CEA is used as a tumor marker for a variety of cancers including colon, breast, rectum, liver, pancreas, stomach and ovaries.

- The CEA test may be used: 1  To monitor the treatment of people diagnosed with colon cancer. 2  It may also be used as a marker for medullary thyroid cancer and cancers of the rectum, lung, breast, liver, pancreas, stomach, and ovaries. 3  An initial CEA test is typically ordered prior to treatment as a baseline value.

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.

Cost-effectiveness analysis Cost-effectiveness analysis (CEA) is a form of economic analysis that compares the relative costs and outcomes (effects) of two or more courses of action. Cost-effectiveness analysis is distinct from cost–benefit analysis, which assigns a monetary value to the measure of effect.ost-effectiveness analyses are often visualized on a cost-effectiveness plane consisting of four-quadrants.

( 1 See above under cancer markers.) 2  DR-70 is a simple blood test - (See above). 3  Hemoccult Test for colorectal cancer tests for blood in the stool. A positive finding warrants having further tests, like a colonoscopy or sigmoidoscopy to detect polyps and tumors.

What Is the Normal CEA Level? The normal value for those taking a CEA, or carcinoembryonic antigen, blood test is 0 to 2.5 micrograms per liter, according to MedlinePlus. For smokers, the normal value range is 0 to 5 micrograms per liter.

- 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.

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.

How high can cea levels go? The other is the Roche method. The Roche method has a wider band of what is considered normal. It's important you understand what testing method your lab uses and to have consistent measurements for the basis of comparison for trending. If you shift labs, expect to have at least 2 CEA tests done to establish the new basis for comparison.

- What is the CEA test, and what are the normal levels? CEA tests determine the amount of carcinoembryonic antigen in the blood, and typical normal levels range from 0 to 2.5 micrograms per liter (mcg/L) of blood, MedlinePlus reports.
