Method for measuring target component in erythrocyte-containing specimen
First Claim
1. A method for measuring a target component in an erythrocyte-containing specimen with a biosensor that comprises an electrode and a detecting portion, comprising the steps of:
- acquiring a plurality of electrical signals derived from the target component in the erythrocyte-containing specimen with the biosensor by continuously applying a constant voltage to the electrode, thereby acquiring the plurality of electrical signals at a plurality of pre-determined time points in a single application of voltage at the detecting portion; and
determining an amount of the target component in the specimen based on the plurality of electrical signals with reference to the relationship between the amounts of the target component and the plurality of signals corresponding thereto.

Abstract
[Object]
To provide a method for measuring a target component in an erythrocyte-containing specimen with high reliability while suppressing the influence of the Ht value of the specimen.
[Solution to Problem]
In the measurement method of the present invention, first, prior to measurement, a relationship between amounts of the target component and a plurality of signals corresponding thereto is provided. Then, a plurality of signals derived from the target component in the erythrocyte-containing specimen are acquired with a biosensor. With reference to the relationship, the amount of the target component in the specimen is determined based on the thus-acquired plurality of signals.
