This testkit helps to save lives all over the world! The MediSmart colorectal occult blood test is an immunochemical test which also makes it possible for users to test for FOB (Fecal Occult Blood) in the comfort of their own home. The test is extremely accurate (more than 99,5%) and has been designed to detect extremely low levels of human fecal occult blood. Test results help to determine GI (gastrointestinal) bleedings which are typical for a number of gastrointestinal disorders such as diverticulitis colitis, polyps, and colorectal cancer. The American Cancer Society and the Centre For Disease Control both recommend an annual FOB test from the age of 50 onwards in order to detect colorectal cancer. The OMEDs (World Organization for Digestive Endoscopy) Colorectal Cancer Screening Committee recommends immunochemical FOB testing in preference to Guaiac based testing because of the often misleading results of Guaiac tests caused by dietary peroxidases, including haemoglobin and myoglobin from meat and uncooked fruits or vegetables.
