	Reference.com/Encyclopedia/Fecal occult blood
		Fecal occult blood is a term for blood present in the feces that is not visibly apparent.
		Fecal occult blood testing - as its name implies - can provide clues as to subtle blood loss in the gastrointestinal tract, anywhere from the mouth to the colon.
		In the event of a positive fecal occult blood test, the next step in the workup is a form of visualization of the gastrointestinal tract (ie: endoscopy, colonoscopy, virtual colonoscopy).

	OIVD: Home-Use Tests - Fecal Occult Blood
		This is a home-use test kit to measure the presence of hidden (occult) blood in your stool (feces).
		Fecal occult blood is blood in your feces that you cannot see in your stool or on your toilet paper after you use the toilet.
		Further testing and examinations should be performed by the physician to determine the exact cause and source of the occult blood in the stool.

	Fecal Occult Blood Test Information on Healthline
		The fecal occult blood test (FOBT) is performed as part of the routine physical examination during the examination of the rectum.
		The FOBT is used routinely (in conjunction with a rectal examination performed by a physician) to screen for colorectal cancer, particularly after age 50.
		Tests that use anti-hemoglobin antibodies (or immunochemical tests) to detect blood in the stool are also used.

	Fecal Occult Blood: The Test
		The main use for the FOBT is as a screen for early colon cancer.
		A secondary use of FOBT is to look for a cause of anemia, such as might be caused by a bleeding ulcer.
		Fecal occult blood tests are done as part of a routine examination and are recommended annually after age 50 (by the American Cancer Society and other major organizations) or as directed by your doctor.

	What Does a Positive Fecal Occult Blood Test Mean? - B01
		Occult means you do not know there is blood in the stool, i.e., you cannot see bright red recognizable blood like you might see if you had bleeding from hemorrhoids.
		Testing for fecal occult blood is commonly used as a cancer screen for colon cancer.
		When the work up to evaluate occult fecal blood is completed (see colon cancer screening article below), about 5% of patients with gastrointestinal bleeding will not have a source for their bleeding found.

	Definition of a Screening Fecal-Occult Blood Test
		One commenter suggested that the current definition of a screening fecal-occult blood test at § 410.37(a)(2) that limits coverage to guaiac-based tests should be expanded to permit coverage of another test.
		Based on our analysis of the preliminary information we have on the new test, we believe that it may have the potential for effective screening for colorectal cancer, and thus, we have agreed with the commenter to broaden the definition in § 410.37(a)(2) to permit coverage of non-guaiac based tests.
		If, for instance, the test is not as effective as the currently covered test, it would not make sense to authorize coverage as permitted by section 1861(pp)(1)(D) of the Act.

	Fecal Occult Blood Test Procedure Information by MedicineNet.com
		Fecal occult blood testing (FOBT) is testing that is performed on samples of stool in order to detect occult blood (blood that is not visible to the naked eye) in otherwise normal–colored stool.
		Fecal occult blood usually is a result of slow (often intermittent) bleeding from inside the upper or lower gastrointestinal tract.
		A fecal occult blood test is done primarily to detect or prevent colon cancer in people without intestinal symptoms.

	Comparison of screening fecal occult blood tests
		Traditional guaiac-based fecal occult blood tests are relatively insensitive for the detection of adenomas and cancer.
		The combination test combines the advantages of the sensitive guaiac tests with the specificity of HemeSelect -- those who test negative by the sensitive guaiac test do not need the expensive immunochemical test; those who test positive by the cheaper test should be confirmed by immunochemistry.
		Assuming that the combination test is made available as a single, multi-specimen card, it certainly would seem to represent an improved fecal occult blood test approach.

	More Sensitive Fecal Blood Test Can Reduce Needless Colonoscopies - CME Teaching Brief® - MedPage Today
		Explain to patients that immunochemical fecal occult blood tests appear to be more sensitive and specific for colorectal cancer than standard guaiac-based tests, but be aware that both tests are subject to both false positives and false negatives.
		Unlike standard guaiac-based tests such as Hemoccult II, the results are not affected by the presence in the diet of vitamin C, animal blood, or foods containing peroxidase (e.g., radishes, turnips, or broccoli).
		To determine whether adding immunochemical FOBT to screening of some patients could reduce the number of false positives and unneeded colonoscopies, the investigators invited people who had a positive guaiac-based FOBT and were awaiting colonoscopy to submit two samples from separate stool samples for immunochemical FOBT.

	Fecal Blood May Signal Upper Gi Bleed
		Combining this test with an immunochemical test may help differentiate bleeding in the upper gastrointestinal tract from bleeding in the bowel, conclude the authors, a team of researchers led by Dr. Don C. Rockey of Duke University Medical Center in Durham, North Carolina.
		Guaiac-based fecal occult blood tests, which check for blood in the feces, are commonly used to screen for colorectal cancer.
		Because positive fecal occult blood test results may indicate either upper GI or lower GI problems, or both, physicians should consider giving patients a second test, called an immunochemical test for human hemoglobin, the researchers suggest.

		A fecal occult blood test (FOBT) is a noninvasive test that detects the presence of hidden (occult) blood in the stool.
		Hidden blood in stool is often the first, and in many cases the only, warning sign that a person has colorectal disease, including colon cancer.
		However, health care providers usually favor the guaiac tests because the large studies that have shown the benefits of colon cancer screening were done with guaiac tests.

		Additional tests are needed to further evaluate your colon and rectum and sometimes your upper gastrointestinal tract, which includes your esophagus, stomach and small bowel.
		Unfortunately, the fecal occult blood test is a relatively insensitive method for colon cancer screening and should be combined with another method that looks directly at the colon at regular intervals.

		Immunochemical tests have the advantage of not reacting with non-human hemoglobin (which is present in meat) or with uncooked fruits and vegetables that may give a positive result with guaiac-based tests.
		For instance, the guaiac tests require dietary restrictions before performing the test since substances found in certain foods, vitamins, or drugs can cause the test to give a positive result even when no cancer is present (this is called a false-positive result).
		Blood is not the perfect marker for colon cancer because it is not shed continuously, not all cancers or polyps bleed, and FOBTs must be performed regularly in order to be effective.
