Description Calprotectin latex turbidimetric assay INTENDED USE Calprotectin Turbilatex, is a latex turbidimetric assay only for the quantitative detection of calprotectin in human stool samples (not to be used for body fluid as blood, serum, plasma, urine, cerebrospinal fluid, oral fluid, synovial fluid or empyema fluid). This assay is simple and widely applicable. This product is optimized for several automated analyser. For professional in vitro diagnostic use only PRINCIPLE Calprotectin Turbilatex® is a latex turbidimetric assay only for the quantitative detection of Calprotectin in human stool samples. This assay is simple, widely applicable and test results are obtained in a very short time. The intended use of the test is exclusively to differentiate IBD patients with inflammation from IBD patients without inflammation and from irritable bowel syndrome (IBS). Calprotectin latex turbidimetric assay is based on agglutination reactions. These involve in vitro aggregation of microscopic latex particles. This aggregation consists in the specific reaction between antigen and antibodies, antigen contained in the sample and the antibodies anti-antigen coated on polystyrene latex particles. The sample is mixed with a suspension containing antibodies against the antigen bound to latex particles. If antigen is present in the sample, it will react with the antibodies and form an aggregate. If no antigen is present in the sample the mixture will keep its appearance as a smooth suspension. Such turbidity is measured as an increase in absorbance at determinate wavelength and is proportional to the quantity of antigen contained in the sample. Catalogue Sample Collection Vial
