CEA is most frequently tested in blood. It can also be tested in body fluids and in biopsy tissue. What is the normal range for CEA blood levels? The normal range for CEA in an adult non-smoker is <2.5 ng/ml and for a smoker <5.0 ng/ml. How is the CEA test used? The best us...
elevated CEA levels can be present in patients with non-cancerous conditions such as inflammatory bowel disease, and studies suggest that CEA screening lacks sensitivity, missing about
Certain substances in the blood, called tumor markers, may be elevated in people with pancreatic cancer. Your doctor may use blood samples to check the levels of these tumor markers, such ascarcinoembryonic antigen(CEA) and cancerantigen 19-9 (CA 19-9). High levels of tumor markers may indi...

further cleavage; ultimately, a tryptic fragment,C4d, remains on the RBC. This C4d glycoprotein carries the Ch/Rg blood group antigens. The antigens are stable in stored serum or plasma, and the phenotypes of this system are most accurately defined in plasma byagglutinationinhibition tests. ...
Blood-based tests in the circulation can complement existing diagnostic tools to improve the performance of breast cancer screening and detection. Among the blood-based tests, the existing CTC method has the advantage of knowing the origin of cancer because tumor cells are generated from cancer, but...
