Abstract
Using a biosensor including a flow path into which blood containing a target is introduced, an upstream electrode pair disposed in the flow path and having a reagent reacting with the target disposed on either of the electrodes, and a downstream electrode pair disposed at a downstream side of the flow path; the method includes a first detection step of detecting a first introduction of blood as far as the upstream electrode pair; a second detection step of detecting a second introduction of blood as far as the downstream electrode pair; a time measurement step of measuring a time difference from the first introduction to the second introduction; and a measurement step of acquiring the value related to the target based on the time difference by using any two electrodes among the upstream and downstream electrode pair after the second introduction is detected.
