Abstract
L'invention concerne un procédé et un dispositif pour l'analyse de résultats de tests visant à déterminer si un fluide testé contient une certaine substance. Le procédé comporte les étapes consistant à détecter ladite substance dans le fluide testé, reçu sur une bandelette réactive ; à produire un signal électrique indiquant la quantité de substance détectée ; à répondre à un signal de sortie pour indiquer la présence ou l'absence d'une quantité prédéterminée de ladite substance contenue dans le fluide testé ; à retarder la détection selon un intervalle de retard prédéterminé ; et à stocker les données détectées à la fin de cet intervalle.
