`
`FAIL JUDGING METHOD AND ANALYZER
`(54)
`
`An analyzer (A) includes a current measurer
`(57)
`(42) for measuring the current flowing between paired
`electrodes (22a); (22b) when a sample is introduced to
`the reagent layer (23) of a sensor (2) and voltage is ap-
`plied across the electrodes, while also including a proo
`essor (3) for analyzing the sample based on the current
`
`after a predetermined reference time point. The analyz—
`er (A) further inciudes a tail determiner (44) which mon-
`itors the change of the current before and after the ref—
`erence time point and determines that the sensor (2) ie
`lmproperwhen the current change does not correspond
`to a predetermined current change.
