Fecal Calprotectin: A Comparison of Two Commercial Enzymoimmunoassays and Study of Fecal Extract Stability at Room Temperature

Background: The aims of the study were: 1) to compare the fecal calprotectin (fCal) assay results with Calprolab？ ELISA (HRP) (Calpro AS) versus our routine method, Elia？ fluoroenzymoimmunoassay (Thermo Fisher), and 2) to determine whether the fCal assay results do not vary following storage of the extract at room temperature for 4 days with the Calpro AS buffer, this being the estimated shipment time from the home of the patient, and an aspect little studied to date.
