Single layer teststrip

摘要

Test element (I) for the optical detection of an analyte, comprises at least partially optical transparent carrier and a single layer reaction film containing a test reagent for the determination of the analyte with a thickness less than or equal to 10 mm (dry). Independent claims are also included for: (1) test element, for the optical detection of an analyte, comprising at least partially optical transparent carrier and a single layer reaction film containing a test reagent for the determination of the analyte, where thickness and porosity of the reaction film and concentration of the test reagent are adjusted, in which a determination of the analyte takes place within the reaction duration of less than 5s (preferably 1-4s) with a signal intensity sufficient for a quantitative regulation; (2) detection of an analyte in a sample, comprising exposing the sample with (I) and quantitative determination of the analyte concentration in the sample; and (3) a test device containing (I) for optical detection of the analyte in the sample.
