The DiaSorin LIAISON® Calprotectin assay is an in vitro diagnostic chemiluminescent immunoassay (CLIA) intended for the quantitative measurement, in human stool, of fecal calprotectin, a neutrophilic protein that is a marker of mucosal inflammation. The LIAISON® Calprotectin assay can be used as an aid in the diagnosis of inflammatory bowel diseases (IBD), specifically Crohn's disease and ulcerative colitis, and as an aid in differentiation of IBD from irritable bowel syndrome (IBS). Test results are to be used in conjunction with information obtained from the patients' clinical evaluation and other diagnostic procedures. The test has to be performed on the LIAISON® Analyzer Family. The DiaSorin LIAISON® Q.S.E.T. Device Plus (Quantitative Stool Extraction and Test) is intended for use in the preparation of human stool specimens for testing in the LIAISON® Calprotectin assay.

The LIAISON® Calprotectin assay is a sandwich assay that uses 2 monoclonal antibodies for capture and detection of calprotectin. The LIAISON® Calprotectin assay must be run on the LIAISON® Analyzer family, a fully automated system with continuous loading. Calprotectin is first extracted from human stool samples with LIAISON® Q.S.E.T. Buffer using either the weigh method, the LIAISON® Q.S.E.T. Device or the LIAISON® Q.S.E.T. Device Plus. The assay incubates extracted sample, calibrator, control, or calibration verifiers with assay buffer and paramagnetic particles coated with a monoclonal antibody that specifically recognizes the calprotectin heterocomplex. Following incubation, a wash cycle is performed to remove any unbound material. An isoluminol conjuqated monoclonal antibody that recognizes calprotectin is then added to the reaction and incubated. The unbound conjugate is removed with a second wash step. Starter reagents are then added and a flash chemiluminescent reaction is initiated. The light signal is measured by a photomultiplier as relative light units (RLU) and is proportional to the concentration of calprotectin present in the calibrators, controls or samples. All assay steps and incubations are performed by the LIAISON® XL Analyzer. The analyzer software automatically calculates the concentration of calprotectin in the sample. This concentration is expressed in ug/g. The Q.S.E.T. Device Plus differs from its predicate Q.S.E.T. Device in that it is provided ready to use, and comes prefilled with the same extract buffer as required for use with the Q.S.E.T. Device, eliminating the need for the user to prepare the buffer and add it to the device themselves. In addition, minor changes to the shape and design of the tube were made.

The ALPCO Calprotectin Chemiluminescence ELISA is an in vitro diagnostic chemiluminescent assay intended for the quantitative measurement of fecal calprotectin, a neutrophilic protein that is a marker of intestinal mucosal inflammation, in human stool. The ALPCO Calprotectin Chemiluminescence ELISA is intended for in vitro diagnostic use as an aid in the diagnosis of inflammatory bowel disease (IBD), specifically Crohn's disease (CD) and ulcerative colitis (UC), and as an aid in the differentiation of IBD from irritable bowel syndrome (IBS) in conjunction with other clinical and laboratory findings. The ALPCO Easy Stool Extraction Device is intended for use in the preparation of human stool specimens for testing in the ALPCO Calprotectin Chemiluminescence ELISA.

The ALPCO Calprotectin Chemiluminescence ELISA is performed on stool samples, collected without preservatives. After an extraction procedure of the stool sample, using either the manual weighing or Easy Extraction Device procedure, the test allows the selective measurement of calprotectin-antigen by sandwich ELISA. A monoclonal capture antibody (mAb) highly specific to the calprotectin heterodimeric and polymeric complexes, respectively, is coated onto the microtiter plate. Calibrators, controls and specimen extracts are incubated. After a washing step, a biotinylated secondary monoclonal detection antibody detects the calprotectin molecules bound to the antibody coated onto the plate. After incubation and a further washing step, a Streptavidin-Horseradish Peroxidase Enzyme conjugate binds to the available biotin on the immobilized secondary antibody. A chemiluminescent substrate is added and read when the substrate glows as a result of its oxidation with the enzyme. The signal is then read on a chemiluminescent plate reader.

Calprest® is an enzyme-linked immunosorbent assay (ELISA) system with colorimetric detection based on the use of polyclonal antibody against calprotectin. Calprotectin present in the diluted sample is bound by the antibody adsorbed to the surface of the plastic well. The enzyme conjugated antibody binds to the captured antigen and subsequently the enzyme catalyzes the conversion of the substrate to a colored product. The intensity of the color is proportional to the amount of conjugate bound, and thus to the amount of captured calprotectin. Concentration of calprotectin in the samples is calculated using the provided standards. EasyCal is a single-use device for stool sample pre-analytical processing that allows the extraction of calprotectin from the specific amount of collected fecal sample required to perform Eurospital's Calprest® and Calprest®NG assays.
