ABSTRACT:
A method and apparatus for performing an enzyme spot test without traditional instrumentation is disclosed. The method utilizes various reagents to allow the visual determination of the presence of an enzyme in a sample above a predetermined critical level. The enzyme reacts with the reagents producing a product according to a reaction which is timed by a chemical fuse. At the end of the reaction, a colored by-product is visible, the color intensity indicating that the enzyme occurs in the sample in quantities above the critical level.
