Abstract
Diagnostic device for the determination of ammonia having a handle, an ammonia indicator layer thereon and an alkaline buffer-containing reaction layer positioned above the indicator layer a distance of 10 to 200 microns by a spacer member. The reaction layer is readily separated from the indicator layer to reveal the latter at the end of the ammonia test.
