ABSTRACT:
A method for improving the accuracy of temperature sensitive diagnostic assays which are carried out using reflectance spectrometers to detect color changes in a solid test system which has been contacted with a fluid test system suspected of containing an analyte whose presence and/or concentration is being sought. The method involves determining the temperature of the solid test material by measuring the reflectance of a thermochromic liquid crystal in close proximity to the solid test material and correcting the result of the assay for a change in temperature from a pre-selected nominal temperature.
