Prediction method of concentration fluctuation of measurement target components in blood using area under blood concentration time curve, and device therefor

A device for predicting a concentration fluctuation of a measurement target component in the blood, comprising:

• an input part for inputting an initial value relating to the amount of a measurement target component of a subject;
• a first collection member for retaining a tissue liquid extracted during a first extraction period from a microhole formed on the skin of the subject;
• a second collection member for retaining a tissue liquid extracted during a second extraction period from the microhole formed on the skin of the subject;
• a measurement part for measuring the amount of the measurement target component contained in the first collection member and the amount of the measurement target component contained in the second collection member;
• and
• an analysis part configured for performing operations, comprising:
• obtaining, as a first measurement value, a value of an area under the blood concentration time curve of the measurement target component during the first extraction period, from the amount of the measurement target component contained in the first collection member;
• obtaining, as a second measurement value, a value of an area under the blood concentration time curve of the measurement target component during the second extraction period, from the amount of the measurement target component contained in the second collection member;
• and
• predicting the concentration fluctuation of the measurement target component in the blood from the initial value, the first measurement value and the second measurement value.
