1. An analysis apparatus comprising:
an electrochemical sensor positioned subcutaneously and configured to continuously detect signal values from a first sample where the first sample is an extracellular fluid in a subject's body comprising a specified substance, the electrochemical sensor comprising:
a first temperature detection unit configured to capture a first temperature value defined as temperature information for the extracellular fluid,a signal detection unit, anda substrate, wherein the signal detection unit comprises:
a working electrode and a counter electrode formed on a surface of the substrate, anda reagent layer, where the reagent layer is immobilized on the working electrode, the reagent layer comprising an oxidation reduction enzyme and an electron transfer substance; a measuring unit configured to measure numerical value information for the specified substance present in a second sample where the second sample is blood from the subject outside the subject's body; a second temperature detection unit configured to capture a second temperature value defined as temperature information for the blood; and a calculation unit configured to calibrate numerical value information for the specified substance in the extracellular fluid from the signal value by referring to the numerical value information for the specified substance in the blood in accordance with the first temperature value and the second temperature value,wherein:
the calculation unit is further configured to acquire a first temperature acquired value defined as the first temperature value at the time when the numerical value information for the specified substance in the blood is measured, the calculation unit is further configured to acquire a second temperature acquired value defined as the second temperature value at the time when the numerical value information for the specified substance in the blood is measured, and when a value calculated for the first temperature acquired value and the second temperature acquired value is equal to or less than a predetermined threshold value, the calculation unit is configured to calibrate the numerical value information for the specified substance in the extracellular fluid from the signal value by referring to the numerical value information for the specified substance in the blood, whereas when the value calculated for the first temperature acquired value and the second temperature acquired value exceeds the predetermined threshold value, the calculation unit is not configured to calibrate the numerical value information for the specified substance in the extracellular fluid from the signal value, with the result that a user of the analysis apparatus is notified by a notifying unit when the calibration of the numerical value information was executed and when the calibration was not executed.
