An improved quality assurance system and method for point-of-care testing are disclosed. The present invention provides quality assurance for laboratory quality tests performed by a blood analysis system or the like at the point of patient care without the need for running liquid based quality control materials on the analysis system. Quality assurance of a quantitative physiological sample test system is performed without using a quality control sample by monitoring the thermal and temporal stress of a component used with the test system. Alert information is generated that indicates that the component has failed quality assurance when the thermal and temporal stress exceeds a predetermined thermal-temporal stress threshold. Alternatively, the present invention provides quality assurance for laboratory quality tests performed by a blood analysis system or the like at the point of patient care by minimizing the need for running liquid-based quality control materials on the analysis system.

Cette invention se rapporte à un système d'assurance qualité amélioré et à un procédé de test au point d'intervention. L'invention fournit une assurance qualité pour des tests de qualité de laboratoire effectués par un système d'analyse de sang, ou semblable, au point d'intervention sans nécessiter des matériaux de contrôle qualité liquides sur le système d'analyse. L'assurance qualité d'un système de test échantillonnaire physiologique quantitatif est effectuée sans utiliser d'échantillon de contrôle qualité en surveillant la contrainte thermique et temporelle d'un composant utilisé avec le système de test. Des données d'alerte sont générées et indiquent que le composant a échoué à l'assurance qualité lorsque la contrainte thermique et temporelle dépasse un seuil de contrainte thermique-temporelle prédéfinie. En variante, l'invention fournit une assurance qualité pour tests de qualité de laboratoire effectués par un système d'analyse de sang, ou semblable, au point d'intervention en réduisant la nécessité de matériaux de contrôle qualité liquides sur le système d'analyse.
