Devices, and methods for the use of same, for collecting and assaying a biological fluid in a single step. One method provides means to control and direct the flow of a sample of the biological fluid directly onto an assay test strip by disposing the assay test strip within a flow control channel in which the internal ambient pressure is maintained in substantial equilibrium with the ambient pressure outside of the flow control channel, such that essentially no pressure gradient is formed within the flow control channel. The devices include the flow control channel, at least one assay test strip and a fluid sample collection container, such as a urine cup, for insertion of the flow control channel therein.

L'invention concerne des dispositifs et leurs procédés d'utilisation destinés à recueillir et à analyser un liquide organique en une seule étape. Un des procédés utilise des moyens de régulation et d'orientation du flux d'un échantillon de liquide organique directement sur une bande de test dans un canal de régulation du flux. On maintient la pression ambiante intérieure en quasi équilibre avec la pression ambiante extérieure du canal de régulation du flux de manière à éviter toute formation de gradient de pression dans le canal de régulation du flux. Ces dispositifs présentent un canal de régulation du flux, une bande de test au moins et un conteneur recueillant l'échantillon de liquide tel qu'un sac collecteur d'urine destiné à être inséré dans le canal de régulation du flux.
