FIELD: medicine. ^ SUBSTANCE: test strap or electrochemical sensor for measurement of analysed substance amount in biological fluid, for instance, content of glucose in whole blood, includes self-size-limiting composition of reagents, in which system of enzymes is used for reaction with analysed substance, reacting system is mixed with water-soluble swelling polymer matrix, containing small water-insoluble particles with nominal size approximately from 0.05 to 20 mcm, preferably approximately from 1 to 10 mcm. Weight ratio of water-insoluble particles to water-soluble swelling polymer matrix constitutes from 1/2 to 2/1. ^ EFFECT: composition of reagents is applied on non-porous base with formation of thin layer approximately 6-16 mcm thick and ensures fast and stable response to sample introduction, remaining insensitive to sample volume. ^ 52 cl, 10 dwg, 4 ex |
