Abstract
Disclosed is an assay for determining the presence and concentration of trypsin inhibitor in urine samples. The assay reagents, which may be used either in the liquid or dry states, include trypsin, a trypsin substrate and a polycarboxylic chelating agent. The inclusion of the chelating agent in the assay has been found to reduce variation in the assay results.
