BIOSENSOR SYSTEM AND TEST SENSORS FOR DETERMINATION OF CONCENTRATION OF ANALYSED SUBSTANCE (VERSIONS) Russian patent published in 2015 - IPC C12Q1/00 G01N27/30 G01N33/487 

FIELD: measurement equipment.

SUBSTANCE: group of inventions relates to the field of biochemistry. A biosensor system and test sensors (versions) are proposed to determine concentration of an analysed substance in a sample. The biosensor system includes a test sensor, comprising at least two electric conductors, a reaction agent containing a binding substance, including at least one water soluble polymer material, buffer salt, a water soluble medium for transfer of one or two electrons, containing at least 20% (wt/wt) of inorganic salt of non-transition metal, a fermentative system and a non-ionic surfactant. The biosensor system also comprises a measurement facility to measure speed of oxidation-restoration reaction of the analysed substance.

EFFECT: proposed group provides for accurate determination of dependence of an output signal of a test sensor, which contains compositions of reagent with low total concentration of salt, from concentration of analysed substance in samples of whole blood in a wide range of levels of hematocrit within the limits of not more than 7 seconds.
