Specimen Required:  
Collect: 3 mL body fluid. Indicate a source on test request form.

Interpretive Data:
The Roche Modular E170 CEA electrochemiluminescent immunoassay is used. Results obtained with different assay methods or kits cannot be used interchangeably. Measurements of CEA have been shown to be clinically relevant in the management of patients with colorectal, breast, lung, prostatic, pancreatic, and ovarian carcinomas. Smokers may have slightly elevated levels of CEA. The CEA assay value, regardless of level, should not be interpreted as evidence for the presence or absence of malignant disease and is not recommended for use as a screening procedure to detect the presence of cancer in the general population. This test is FDA cleared but is not labeled for use with body fluids.
