Abstract

A device and method for verifying correct performance of an optical clinical assay system is provided. The device consists of a heated support stage (27), containing an optical window (30) through which light (22) emitted from a light source (21) can pass. Additionally, the device includes an. optical shutter (12) with a backing (13) and a circuit board (10). An algorithm or method controls the rate in which an opaque optical reference is revealed to the detection apparatus and the algorithm or method is selected to simulate the reaction rates of one or more levels of clinical analytes reacting with a test reagent.
