Described is an assay for trypsin inhibitors in urine. The assay involves contacting a urine test sample with a buffered assay medium comprising trypsin, a substrate for trypsin which will produce a detectable response when cleaved by trypsin and a polycarboxylic chelating agent in sufficient quantity to inhibit interference with the assay from calcium present in the urine test sample, and correlating the concentration of the trypsin inhibitor with the detectable response from the cleaving of the substrate. Also described is a dry assay device having trypsin, buffer, a trypsin substrate and a chelating agent in an absorbent carrier for detecting the presence of trypsin inhibitor in urine test samples.
