Abstract
An apparatus for analyzing a body-fluid sample, such as a urine sample, disposed on a reagent pad is provided with means for illuminating the reagent pad on which the body-fluid sample is disposed, means for detecting light received from the reagent pad and generating a first reflectance signal at a first time and a second reflectance signal at a second time, and means for assigning a color to the body-fluid sample based upon the magnitudes of the first and second reflectance signals. The means for assigning the color to the body-fluid sample may include means for determining a pair of color coefficients each of which has a magnitude based upon the magnitudes of the reflectance signals and means for assigning the color to the body-fluid sample based upon the magnitudes of the color coefficients.
