Test strip for optical- or amperometric determination of e.g. blood sugar, comprises optically-transparent substrate, with thin layer of reagent painted onto it

摘要

The substrate (26) is optically-transparent. Reagent-containing, thin layer carrier medium is coated onto it. Independent claims are also included for the following: (1) an associated measurement instrument with three optical sensors, two directed towards the reaction field, one towards the reference surface; and (2) a method of calibrating the optics.
