i-TRA Turbidimetric is a latex agglutination test based on turbidimetric method for the quantitative in vitro determination of transferrin (Tf) in human feces. The reagent contains latex particles coated with goat anti-human transferrin IgG in a buffer. Tf present in the patient's stool solution reacts with the latex-coated particles, causing agglutination that can be measured with a photometer. The degree of turbidity is proportional to the concentration of Tf in the sample.
