Abstract: A microfluidic device for obtaining a homogenous plasma-reagent mixture includes a collection module for blood plasma arranged to passively separate the blood plasma from a drop of blood taken, a capillary channel in fluidic connection with said collection module and a storage reservoir for a reagent in fluidic connection with said capillary channel. The device also contains a mixing chamber in fluidic connection with said capillary channel equipped with a flow outlet. The volume of said storage reservoir for reagent being greater than the sum of the volumes of said capillary channel and of said mixing chamber, setting the reagent in motion, after saturation of said capillary channel with blood plasma, induces a flow of the homogenous plasma-reagent mixture from the flow outlet.
