What is a fecal occult blood test?
This test kit is 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.
Why is the faecal occult blood (FOB) test done?
Patient should do this test, because blood in the feces may be an early sign of a digestive condition, for example abnormal growths (polyps) or cancer in your colon.
Intended Use of fecal occult blood test
This Test is a rapid, direct immunoassay for the qualitative detection of human occult blood in feces. The assay is designed to detect lower levels of colorectal bleeding than other biotechemical detection methods. The test principle is an immunochromatographic sandwich method, which employ specific polyclonal antibodies to selectively identify hemoglobin in test samples. The result is very specific, and easier to interpret than those of guaiac-based test. The sensitivity is very high with the ability to detect 0.2µg/ml hemoglobin in feces. In addition, the accuracy of the test is not affected by interfering substances, and dietary restriction is not necessary.
