Abstract

La présente invention concerne un système d'interprétation de données de résultat de test de pathologie et de communication en temps réel qui comprend un serveur en communication fonctionnelle avec une source de données de résultats de test de pathologie à travers un réseau étendu. Le serveur a un dispositif de commande de récupération pour s'authentifier auprès de la source de données de résultats de test de pathologie en utilisant des justificatifs d'identité fournis, récupérer des données de résultats de test de pathologie à partir de la source de données de résultats de test de pathologie, un dispositif de commande d'interprétation pour interpréter les données de résultats de test de pathologie obtenues à partir de la source de données de résultats de test de pathologie, et un dispositif de commande de communication configuré pour communiquer une alerte en temps réel électronique à un dispositif électronique en conséquence.
