Abstract

One aspect of the present invention is a reagent test strip that includes: a) a top support layer including a sample aperture; b) a membrane that includes a reagent system for indicating the concentration of a target; c) a spreading layer; d) a bottom support layer including a measuring port in substantial alignment or approximate alignment with the sample aperture. Preferably, the membrane is affixed to the top support layer; the membrane is positioned between the top support layer and the bottom support layer; the spreading layer is positioned above the top support layer and in substantial or approximate alignment with the sample aperture; and a fluid applied to the spreading layer, passes through the sample aperture and contacts the membrane. Figure (1) shows a perspective and side view of the preferred embodiment of a test strip of the present invention.
