1. A method for determining the concentration of an analyte in a sample of fluid, said method comprising:

  • contacting said sample with a matrix comprising a signal producing system that produces a colored product on said matrix in an amount proportional to the amount of analyte in said sample;

    illuminating a surface of said matrix with an illumination means;

    collecting light from said surface with a light detection means to obtain an optical measurement;

    obtaining an ambient temperature value proximal said matrix using said light detection means; and

    determining said analyte concentration in said sample from said optical measurement using an algorithm that employs said ambient temperature value.
