A DRY STICK DEVICE AND A METHOD FOR DETERMINING AN ANALYTE IN A SAMPLE

摘要

A novel and improved dry stick construction for the determination of an analyte in a sample is provided. The dry stick device comprises: (i) a solid support comprising a cavity, and (ii) at least one dry reagent 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, wherein the cavity comprises the at least one dry reagent. The present invention also provides an automated or semi-automated system. Additionally the present invention provides an automated or semi-automated system for optimising the production performance of a milk producing animal herd.
