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.
For treatment, recurrence monitoring: When CEA levels are initially elevated and then decrease to normal after therapy, it means the cancer has been successfully treated. A steadily rising CEA level is often the first sign of tumor recurrence. CEA test may be used in combination with other tumor markers in the evaluation of cancer. Not all cancers produce CEA, and a positive CEA test is not always due to cancer. Therefore, CEA is not recommended for screening the general population.
