Reference:
| REFERENCE RANGE ECLIA Method ug/ml In a group of 500 healthy persons, 95% of the serum CEA values were found to be between 0 and 4.6 ng/ml. The upper limit was 10.0 ng/ml. Values obtained in the range 3.5-10.0 ng/ml were mainly from smokers. In non-malignant diseases also (e.g. hepatitis alcohol mediated liver diseases, diverticulitis, ulcerative colitis, bronchitis and pancreatitis) the CEA values did not as a rule exceed the aforementioned upper limit. Substantially higher values are often found when malignant disease is present, particularly in patients with gastro-intestinal tumours or carcinoma of the breast, lungs, medullary thyroid and pancreas. However low CEA values do not rule out the existence of a tumour. |
Why is the Test Done?
To help determine whether cancer is present in the body, although it not recommended as a general population screening test; to monitor cancer treatment, including response to therapy and recurrence; to help in staging of cancer, when your doctor thinks your symptoms suggest the possibility of cancer; before starting cancer treatments as well as at intervals during and after therapy.
