Patent

CA 2620009

A system and method is disclosed which relates to reading test strips. The method may include reading and storing initial values of a front photodiode and a rear photodiode, reading current values of the front and rear photodiodes, detecting at least one change between initial and current values in the front or the rear photodiodes, comparing the detected value change of one of the photodiodes with the value of the other photodiode, and determining a condition of the test strip in response to the resulting comparison.

La présente invention a trait à un système et un procédé de lecture de bandelettes réactives. Le procédé peut comprendre la lecture et le stockage de valeurs initiales d'une photodiode avant et d'une photodiode arrière, la lecture de valeurs courantes des photodiodes avant et arrière, la détection d'au moins une modification entre les valeurs initiales et courantes dans les photodiodes avant ou arrière, la comparaison de la modification de valeurs détectée d'une des photodiodes avec une valeur de l'autre photodiode, et la détermination d'une condition de la bandelette réactive suite à la comparaison obtenue.
