Vitassay Transferrin Turbidimetry kits for the quantitative detection of Transferrin in human stool samples. Vitassay Transferrin –Turbidimetric Assay- is a rapid Turbidimetric assay for the quantitative detection of transferrin in human stool samples. Simple, non-invasive and highly sensitivity assay for the detection of human transferrin in feces that helps in the search for gastrointestinal bleeding problems. This product has been optimized for several automated analyzer. Transferrin 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. Transferrin (Tf) is an iron-transporting protein (molecular weight=76.500 Da) that is synthesised mainly in the liver and os present at a concentration of 2.0-3.0 g/L in normal serum. The blood concentration of Transferrin is 1%-2% that haemoglobin (Hb), but Transferrin is highly stable and is considered to be a more sensitive indicator of bleeding than Hb, even when the intestinal retention time for faeces is long.
