Carcinoembryonic Antigen Test (CEA) ... You doctor can also use the test results to help determine if a cancer treatment is working. ... Elevated levels of CEA occur when the CEA is higher than 3 ...


Carcinoembryonic antigen (CEA) is used as a tumor marker. An elevated or rising CEA level indicates cancer progression or recurrence. Read on to learn about the meaning of different CEA blood ranges, the CEA test, and how to know what a healthy blood test range is for CEA.


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.


The carcinoembryonic antigen (CEA) test measures the level of 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.


High False-Positive Rate of Elevated CEA Seen in Patients With Resected Colorectal Cancer. By Charlotte Bath ... a false-positive was described as a CEA level higher than the upper range of normal (ie, ≥ 5.1 ng/mL) with no evidence of cancer on either imaging studies or other diagnostic procedures, with either follow-up of (1) at least 1 year ...


1 in 4 is pretty significant. I have a friend who is dealing with rectal cancer. She is seeing a different oncologist and the same topic came up about CEA rise and when one should worry. She said he also has patients that have had CEA levels reach as high as 20-22 and not have cancer as a result. I agree a better test needs to be developed.


My CEA has risen in 6 month intervals over the last 18 months from 2.7 to 3.2 to 4.3 . I have tested negative for blood in stool and colonoscopy in October '07 was clean. In December '07 I had AST of 35 in contrast to AST of 27 in Oct '06. I am not experiencing any symptoms. I do not drink more than ...


What Are the Causes of Elevated CEA? Elevated carcinoembryonic antigen is caused by conditions such as cancer, pancreatitis, smoking infections and cirrhosis of the liver. The normal level of CEA in an adult that does not smoke is 2.5 ng/ml, while normal level in a smoker is 5.0 ng/ml, according to MedicineNet.


Hence, liver work-up is needed to assess any patient with an elevated CEA. A damaged liver may further augment elevated CEA levels due to cancer. The increased circulating CEA observed in some patients with active ulcerative colitis tends to correlate with severity and extent of disease and usually returns to normal with remission.


CEA is a type of protein in the body. Babies in the womb have high levels of it. After birth, levels drop way down. Healthy adults have a very low level, but some types of cancer can cause it to rise.
