A new reactive strip was used in a hospital admission unit, to detect amylasuria in the urine of 76 patients consulting for abdominal pain (population A) and of 68 unselected patients (population B). Detection on admission by this method was concordant with subsequent laboratory detection in 93% of the cases. The fast test was positive for amylasuria in 17 patients: 13 (17.1%) in population A and 4 (5.9%) in population B. The 8 patients recorded as "+" had moderate amylasuria with multiple but ill-defined symptoms mostly abdominal. The 9 patients recorded as "++" had marked amylasuria highly suggestive of an abdominal disease, including 4 cases of chronic pancreatitis.
