Abstract:
1. A device for determination of an analyte in a liquid sample, comprising: a) an elongated support to be gripped extending along a reference direction having a proximate gripping zone and a distal portion away from said gripping zone; b) a first means for capillary diffusion in said reference direction, integral with the support to be gripped, comprising a downstream zone which is accessible to external observation, and an upstream zone opposite to said downstream zone along said reference direction; c) a movable member movably mounted inside said support along said reference direction, for taking up the liquid sample, comprising a second means for capillary diffusion extending in said reference direction having a distal collection zone for collecting said sample, and a proximal transfer zone opposite to said distal collection zone along said reference direction, said movable member being mounted on said support so that it can move between a protruding position and a retracted position, wherein: d) means for opening and closing said opening in said support, respectively in the protruding and retracted positions of said movable member; e) a set of predetermined reagents for at least one of detection and quantitative analysis of the analyte, comprising
