Simple, non-invasive and highly sensitivity assay for the detection of human hemoglobin in feces that helps in the search for gastrointestinal bleeding problems. This product has been optimized for several automated analyzer.
INTRODUCTION
The increased amount of hemoglobin (hHb) in feces is the main symptoms of illnesses accompanied by hemorrhagic lesions in the digestive tract, particularly in the lower digestive tract. Therefore, measuring the amount of hemoglobin in feces is an effective method for the early detection and treatment of colon cancer and other diseases of the lower digestive tract that are accompanied by hemorrhaging.
PRINCIPLE
Vitassay FOB –Turbidimetric Assay- is a quantitative turbidimetric assay for the detection of human hemoglobin in human solid stool samples. FOB Turbidimetric Assay is based on antigen-antibody agglutination reactions between the antigen contained in the sample and the antibodies anti-antigen coated on polystyrene latex particles. Such agglutination is measured as an increase in absorbance proportional to the quantity of antigen contained in the sample. The use of two external controls, Control 1 and Control 2, is used to verify that the test is working properly
