Abstract: A reflectometer and method of use for measuring an amount of analyte in a sample are provided. The reflectometer can include a plurality of reading heads for obtaining reflectance information from discrete regions on a lateral flow test strip. The reflectance information is processed to obtain a digital value for the reflectance. The discrete regions can include a test zone and at least two control zones that each has a differing amount of detection moiety binding substance. The digital values for each control zone can be employed to establish a high end standard and a low end standard. The digital value for the test zone interpolated to the standards to obtain an accurate quantitative value for the analyte in the sample.

Abstract: Lateral flow immunochemistry testing systems and methods are provided. A system can include a tester substrate with at least two control lines and at least one test sample line. A test sample with an unknown amount of analyte can be deposited on the tester substrate and the test sample can move along the tester substrate, to contact the at least two control lines and the at least one test sample line. A measuring device can be used to compare the at least one test sample line to the at least two control lines to give a quantitative value of the amount of analyte present in the test sample.
