Toutes les questions que vous vous êtes toujours posées sur le fonctionnement des capteurs de glucose

The aim of this article is to give a clear and comprehensive overview of the basic principles of continuous glucose monitoring using a subcutaneous glucose sensor. One will consider successively the concepts of sensor's signal, the linearity of the response to glucose, the specificity of the measurement, the principle of calibration, and finally the relationship between the glucose concentration in the interstitial fluid, measured by the sensor, and blood glucose. We wish in this article to show how the development of the systems which are available in current clinical practice had to overcome many obstacles and, therefore, represents a remarkable achievement, both technological and conceptual.
