Reference Range:Blood: Negative
Use:This test addresses many of the weakness of the guaiac test (GT) currently used. The FIT has superior sensitivity and specificity. The FIT sensitivities for cancer are 66 to 82 percent vs. GT sensitivities of 13 to 39 percent; however, the sensitivities for polyps less than 1 cm are more modest at 20 percent. The FIT uses antibodies specific for human globulin and, unlike the guaiac test, is specific for colorectal bleeding and not affected by diet or medications. There is some evidence that FIT use improves patient participation in screening for colorectal cancer. In 2004, Centers for Medicare and Medicaid Services (CMS) concluded that adequate evidence existed to determine that the FIT is an appropriate and effective colorectal cancer screening test for detecting fecal occult blood in Medicare beneficiaries aged 50 years or greater.
