Abstract
The present invention relates to a composition which reduces the measurement error caused by the effect of hematocrit in a biosensor and to a biosensor comprising the same. Specifically, the invention relates to a reagent composition comprising an enzyme, an electron transfer mediator, a water-soluble polymer, and bile acid, and to a biosensor comprising a reagent layer formed of the composition. The reagent layer reduces the measurement error caused by the effect of hematocrit in the biosensor.
Claims20
A reagent composition for biosensors, comprising an enzyme, an electron transfer mediator, a water-soluble polymer, and bile acid.
A a biosensor for measuring the concentration of a specific component in a sample, wherein bile acid is contained in a reagent layer comprising a reagent which reacts specifically with the specific component in the sample.
An electrochemical biosensor for measuring the concentration of a specific component in a sample containing erythrocytes, the electrochemical biosensor comprising:
- a substrate;
- a plurality of electrodes formed on the substrate;
- a reagent layer formed across the plurality of electrodes on the substrate and serving to react with the specific component in the sample to generate a charge corresponding to the concentration of the specific component;
- and
- bile acid for reducing the effect of hematocrit on the concentration of the specific component.
A method for measuring the concentration of a specific component in a sample, the method comprising the steps of:
- mixing the sample with bile acid to prepare a sample solution;
- and
- measuring the concentration of the specific component in the prepared sample solution using a biosensor.
