Abstract
A reagent strip is provided for measuring the concentration of an analyte in a liquid test sample, such as glucose or cholesterol in whole blood. The reagent strip includes a testing pad containing a color-forming reagent system specific to the analyte. The testing pad is disposed so that a side with relatively small pores defines a testing surface and an opposite side with relatively larger pores defines a sample-receiving surface. A porous sample transport medium is attached to the sample-receiving surface. A change in coloration caused by the color-forming reagent system at the testing surface is quantitatively related to the concentration of the analyte in the liquid test sample. The reagent strip may optionally include a rigid support member which facilitates evaluation of the change in coloration by mechanical viewing means. Also provided is a method for determining the concentration of an analyte in a liquid test sample.
