Abstract
A test strip incubation device and method for developing a test strip having a reagent test pad disposed thereon, the reagent test pad requiring an incubation time, which allows greater accuracy and reliability of test results as well as a narrower window of PASS and FAIL indication concentrations. The device comprises a test strip holder which allows a wetted reagent test pad to be vertically stored in an enclosed reaction chamber during the incubation period. The reaction chamber is bounded by a substantially clear material to allow the user to easily observe the status of the reagent test pad held in the reaction chamber. The enclosed reaction chamber provides a high humidity environment for minimizing water evaporation from the reagent test pad during the incubation period. The device may be economically formed from low cost materials, is simple to use and facilitates disposal of the sample material after testing. The device is advantageously used in combination with a storage device which includes recesses for easy storage of several devices and allows viewing of the reagent test pads. The method comprises the steps of wetting the reagent test pad and vertically placing the re…
