A method for noninvasive measurement of glucose in a tissue of a subject, including the steps of bringing an adaptation device, which has a shape similar to a measurement probe, into contact with a skin part of a subject for stretching the skin part of the subject under a pressure that is higher than a pressure per unit area applied by the measurement probe during the non-invasive measurement, maintaining the contact for a predetermined period of time followed by relieving the contact, bringing the measurement probe into contact with the stretched skin part of the subject for the non-invasive measurement, collecting signals emitted from the subject, and estimating a glucose concentration based on the collected signals.
