Because there are different methods for measuring CEA, it’s best to use the same test method for monitoring levels over time in order to be able to compare test results most effectively. CEA tests alone are rarely used to determine the stage of cancer or the effectiveness of treatment. For...
【13】People exposed to certain animal antigens may develop antibodies to CEA that might affect CEA levels and lead to unreliable results. Smokers are highly likely to get false-positive results; therefore, the test is unreliable in active smoke...
A normal result is typically less than 2.5 nanograms per milliliter. Results might vary between labs. A higher-than-normal CEA level that increases over time might signal that your cancer has grown or has come back after treatment. But high levels of CEA do not always mean you have cancer...
Results Levels of serum SCC,CYFRA211 and CEA in the cervical cancer group were higher than those of the benign cervical disease group and the control group,and the cervical benign disease group were higher than the control group,the difference were statistically significant (P <0.05). The serum...

A CEA test can't tell you what kind of cancer you have, or even whether you have cancer. ...
level indicates progression or recurrence of the cancer. This must be confirmed , as the CEA test by itself is not specific enough to substantiate a recurrence of a cancer. In addition, levels >20 ng/ml before therapy may be associated with cancer which has already spread (metastatic disease...

Results The levels of serum CEA, AFF3, CA199 in the pancreatic cancer group were significantly higher than those in the control group (P<0.05), and the relative expression level of serum miR-429 was also significantly higher than that in the control group (P<0.05). The positive rates of...
All three groups were tested for serum markers, and the diagnostic coincidence rate and sensitivity of combined examination were compared.Results:Serum serum levels of CEA, AFP, CA724 and CA125 in observation group 1 were higher than those in observation group 2 and control group, P <0.05;The...
