<p>PROBLEM TO BE SOLVED: To provide a biological sample measurement apparatus capable of increasing the measurement accuracy under a low temperature.SOLUTION: The biological sample measurement apparatus includes: a mounting part 4 mounted with a biological sample measuring sensor 3 to which a biological sample reactive to a reagent is applied, the biological sample measuring sensor 3 being provided on an electrode section including at least a working electrode 9 and a counter electrode 8; and a voltage applying part 12 that applies a voltage to the electrode section of the biological sample measuring sensor 3 mounted to the mounting part 4. The biological sample measurement apparatus further includes: a first amplifier connected to the electrode section of the biological sample measuring sensor 3 to amplify a signal output from the electrode section at a first amplification degree; a second amplifier that amplifies the signal at a second amplification degree larger than the first amplification degree; and a control unit 20 that selectively uses the first amplifier or the second amplifier. The control unit 20 compares a signal output from the first amplifier before starting the measurement with a preset threshold value, and when the signal output from the first amplifier is smaller than the threshold value, selects the second amplifier.</p> |
