Abstract
An improved test strip for determining the presence or concentration of unknown or a constituent in a liquid test sample is disclosed. The test strip comprises a support strip and a test pad, wherein the test pad includes a carrier matrix incorporating a reagent composition capable of interacting with the constituent of interest to produce a detectable or measurable response. The test strip further comprises an infrared dye, applied either to the support strip or incorporated into a test pad, which ensures proper alignment of the test strip in an apparatus having a detection system for the detectable or measurable response. The improved test strip reduces the number of erroneous assays for the constituent of interest.
