CA 2173358

A device and method for its use in diagnostic assays are provided. The device comprises at least one assay path (2), where an assay path includes a main flow path (4), and at least one side reagent channel (6). The main flow path (4) begins at a sample addition port (10), continues through a main reagent area (12) into an incubation area (18) and ends in a waste area (20). At least one fluid interruption means (28) located at various positions along the main flow path (4) and side reagent channel (6) upstream from the incubation area provide for control over reagent interaction and fluid flow through the device.

L'invention se rapporte à un dispositif et un procédé s'utilisant dans des méthodes de diagnostic. Le dispositif comporte au moins une voie de dosage (2) comprenant une voie d'écoulement principale (4) et au moins un canal latéral (6) pour le réactif. La voie d'écoulement principale (4) commence au niveau d'un orifice (10) par lequel on ajoute un échantillon, continue et traverse une zone principale du réactif (12) pour pénétrer dans une zone d'incubation (18) et se termine dans une zone à déchets (20). Au moins un élément d'interruption (28) de l'écoulement du fluide situé à différentes positions le long de la voie principale d'écoulement (4) et le canal latéral (6) du réactif situé en amont de la zone d'incubation assurent le contrôle de l'interaction du réactif et de l'écoulement du fluide dans le dispositif.
