Abstract
(EN)
The instant diagnostic system includes a measurement device including a laser diode and communicatable with a computer (S10). The diagnostic system further includes a memory medium readable by the computer and storing computer instructions executable by the computer. The instructions include the following sequential, non-sequential, or independent steps. A template relating to a beam profile of the laser diode along a flow path of the measurement device is built (S40). A fluorescent sample is captured by the measurement device (S50). The sample is time-wise aligned to the template (S60). The sample is normalized relative to the template (S70). The normalized sample is integrated to determine a total amount of fluorescence in the sample (S80).

La présente invention concerne un système de diagnostic instantané comprenant un dispositif de mesure muni d'une diode laser, capable de communiquer avec un ordinateur (S10). Le système de diagnostic comprend en outre un support mémoire pouvant être lu par l'ordinateur et qui stocke des instructions informatiques pouvant être exécutées par l'ordinateur. Ces instructions comprennent les étapes séquentielles, non séquentielles ou indépendantes suivantes: on construit un modèle représentant un profil de rayonnement de la diode laser le long d'une voie de flux du dispositif de mesure (S40); le dispositif de mesure capture un échantillon fluorescent (S50); on procède à un alignement chronologique de l'échantillon sur le modèle (S60); on normalise l'échantillon conformément au modèle (S70); et on intègre l'échantillon normalisé afin d'obtenir la quantité totale de fluorescence de l'échantillon (S80).
