Abstract: A blood glucose measurement reagent includes: an enzyme having glucose as a substrate; a mediator; a chromogenic indicator; and an aromatic hydrocarbon having at least one sulfonic acid group. A sensor chip includes: a supply port through which blood is suppliable; a flow path having the supply port formed at one end thereof; and a reagent located in the flow path, the reagent being the blood glucose measurement reagent; wherein the sensor chip is mountable on a blood glucose meter for measuring blood glucose in the blood.

Abstract: Provided is a component measuring apparatus configured to determine a functional form that describes wavelength characteristics of a variation attributable to scattering (S (?)). The apparatus then determines unknown one or more coefficients (p, q) based on a first relational expression that involves a variation attributable to absorption (H (?1)) and a group of second relational expressions that do not involve variations attributable to absorption (H (?2a), H (?2b), H (?2c)). The apparatus then corrects an absorbance measured at an arbitrary wavelength (?) using a function where the one or more coefficients (p, q) are applied to the functional form so as to reduce or eliminate at least the effects of scattering of light.
