Abstract

Procédé de détermination de la contamination d'un biocapteur dans lequel le biocapteur est chargé dans un appareil de mesure de test, puis un échantillon est appliqué. Des première et seconde tensions de test prédéterminées sont appliquées entre des électrodes espacées du biocapteur pour des premier et second intervalles de temps prédéterminés respectifs. Des première et seconde valeurs de courant sont mesurées pendant les premier et second intervalles de temps prédéterminés respectifs. Des valeurs de référence sont déterminées sur la base des première et seconde valeurs de courant mesurées. Sur la base d'une ou de plusieurs des valeurs de référence, une détermination de la contamination est effectuée. Le rapport de la concentration d'analytes de l'échantillon peut être supprimé sur la base de la détermination.
