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.

1. An analytical test device having a front and a back, comprising:(a) a top element having a display port; (b) a bottom element comprising a descending contacting surface in front, an upper plane in back and an interposed ascending slope, wherein the lower end of the descending contacting surface is connected to the lower end of the ascending slope and the upper end of the ascending slope is attached to the upper plane; and (c) a strip sandwiched between the top and bottom elements comprising, in fluid communication, an absorbent membrane in the front and a reaction membrane in the back having one or more reagents that form a reaction complex with an analyte in a fluid sample; wherein the reaction membrane is visible through the display port and the absorbent membrane extends along at least the upper end of the slope.
