Summary: | Dry chemistry reagent system, kit and method for detection of an analyte such as glucose, cholesterol, urea, antigen or antibody. The reagent system is a porous membrane or bibulous film having a porosity gradient from one planar surface to the other. In the membrane are uniformly distributed an indicator, a flow control agent and a reagent cocktail. The membrane is also modified by a conditioning agent. |
