Profile: Aerscher Diagnostics develops quality point of care occult blood testing products available on the market today. Our hemaprompt and hemaprompt FG are FDA approved & CLIA waived test systems. The use of guaiac as a test for the presence of blood is based on the oxidation of phenolic compounds present in guaiac to quinones, resulting in the production of a blue color. If blood is present, the heme portion of the hemoglobin molecule can function in a pseudoenzymatic manner, catalyzing the release of oxygen from hydrogen peroxide which in turn causes the oxidation of guaiac. Feces or gastric contents containing occult blood contacts the guaiac impregnated paper and a pseudoperoxidase reaction occurs when developing solution is brought into contact with the guaiac paper, by pulling the tab. The test paper will turn blue in less than 60 seconds in the presence of more than 2mg hemoglobin/ gram of feces, and will gradually fade in 5 - 15 minutes. It will also turn blue in the presence of more than 0.01 mg hemoglobin/ ml of gastric fluid in less than 60 seconds.
