摘要 |
The present invention relates to a dry stick test device for the determination of an analyte in a sample by means of a chemical assay. The device comprises: (i) optionally a solid support, (ii) at least one reagent pad comprising a 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 moistened state, and (iii) a development pad which is located in contact with the at least one reagent pad, optionally between the solid support and the at least one reagent pad, said development pad comprises at least one controlling compound capable of providing a condition required for the reagent to react with the analyte to provide a detectable signal, wherein the at least one reagent pad and the development pad are arranged to avoid precipitation of sample component(s) on the top-face of the device.
