It is important to note that a test that is positive for CEA may not always be indicative of cancers. It is due to this reason that this test is not used to screen for cancers. The CEA blood test normal range is from 0 to 2.5 micrograms per liter.
A CEA test is most useful to monitor patients who already have been diagnosed with a type of cancer that is known to produce CEA. Not all cancers produce CEA. Increased levels of CEA may be found in the following cancers: 1  colorectal (colon) cancer. 2  medullary thyroid carcinoma.
