Abstract
Test strip device for accepting a liquid sample and forming an even fluid front across the test strip. When the sample is applied to a contacting surface, it runs down the surface where it collects between the contacting surface and a slope surface. As the sample collects, it evenly reaches fluid flow contact with an absorbent membrane. As a result, the sample forms an even fluid front across the membrane, improving the performance of the test strip device. Methods for using the device to accept a sample and to detect an analyte in the liquid sample are also provided.
