Title
(EN) SYSTEM AND METHODS FOR PROCESSING ANALYTE SENSOR DATA FOR SENSOR CALIBRATION
(FR) SYSTEME ET PROCEDES DE TRAITEMENT DE DONNEES DE DETECTION D'ANALYTE EN VUE DE L'ETALONNAGE D'UN DETECTEUR
Abstract
(EN)
Systems and methods for processing sensor analyte data are disclosed, including initiating calibration, updating calibration, evaluating clinical acceptability of reference and sensor analyte data, and evaluating the quality of sensor calibration. The sensor can be calibrated using a calibration set of one or more matched sensor and reference analyte data pairs. Reference data resulting from benchtop testing an analyte sensor prior to its insertion can be used to provide initial calibration of the sensor data. Reference data from a short term continuous analyte sensor implanted in a user can be used to initially calibrate or update sensor data from a long term continuous analyte sensor.

L'invention concerne des systèmes et des procédés de traitement de données de détection d'analyte, qui comprennent la mise en oeuvre d'un étalonnage, la mise à jour de l'étalonnage, l'évaluation de l'acceptabilité clinique des données de référence et des données de détection d'analyte, et l'évaluation de la qualité de l'étalonnage du détecteur. Le détecteur peut être étalonné à l'aide d'un ensemble étalonnage comprenant un ou plusieurs détecteurs et des paires correspondantes de données d'analyte de référence. Les données de référence, obtenues à partir des essais auxquels on a soumis un détecteur d'analyte avant l'installation de celui-ci, peuvent être utilisées pour mettre en oeuvre l'étalonnage initial des données de détection. Les données de référence provenant d'un détecteur d'analyte courte durée en continu implanté sur un utilisateur peuvent être utilisées pour l'étalonnage initial ou la mise à jour initiale des données de détecteur provenant d'un détecteur d'analyte longue durée en continu.
