Dry stick device construction and method for determining an analyte in a sample using said dry stick device

Abstract

A novel dry stick device construction for the determination of an analyte in a sample is provided. The device comprises: (i) optionally a solid support, (ii) at least one reagent pad comprising a reagent or a combination of reagents capable of reacting with the analyte, a derivative of said analyte or an indicator compound for said analyte to provide a detectable signal when in a moistened state, the at least one reagent pad providing a first environment for said reagent(s), said first environment permitting an improved storage stability of the reagent(s) and dry stick device when in a non-moistened state, and (iii) a regulating pad being in contact with the at least one reagent pad, the regulating pad creating a second environment for said reagent(s), when in a moistened state, said second environment permitting an increased rate of reaction between the analyte and the reagent.
