Disclosed is a fluidic gating device having a plurality of test flow paths, each with an end region, the device comprising: a fluid reservoir or sample application region provided upstream from at lease one indicator flow path, wherein the fluid reservoir or sample application region is separated from the indicator flow path/s by at least one obstacle to flow; and wherein the obstacle to flow is operably associated with the end region of a test capillary flow path, such that the presence of the test liquid at the end region of an associated test capillary flow path reduces or abolishes the obstacle to flow, thereby allowing a liquid to flow from the fluid reservoir or sample application region and along an indicator flow path.

L~invention concerne un dispositif de portillonnage liquide ayant une pluralité de voies d~écoulement d~essai, ayant chacune une région d~extrémité. Le dispositif comprend : un réservoir de liquide ou une région d~application d~échantillon fournie en amont à partir d~au moins une voie d~écoulement indicateur, lequel réservoir de liquide ou région d~application d~échantillon est séparé du ou des voies d~écoulement indicateurs par au moins un obstacle à l~écoulement ; celui-ci est fonctionnellement associé avec la région d~extrémité d~une voie d~écoulement capillaire d~essai, de sorte que la présence du liquide d~essai dans la région d~extrémité d~une voie d~écoulement capillaire d~essai associé réduit ou élimine l~obstacle à l~écoulement, permettant de ce fait l~écoulement du liquide du réservoir de fluide ou de la région d~application d~échantillon et le long d~une voie d~écoulement indicateur.
