Abstract: Disclosed is a system for rapid analysis of a capillary blood sample from a subject, intended for detecting the presence of at least one analyte in the capillary blood sample. The rapid analysis system includes an analysis module in which is incorporated at least one immunochromatographic strip. The analysis module includes: a pricking member, suitable for generating a drop of capillary blood; and a collecting member, including a fixed duct, suitable for capillary blood to flow therethrough. The duct has an inlet suitable for collecting the drop of capillary blood, and an outlet, arranged opposite the deposition area and suitable for depositing the drop of capillary blood onto the deposition area, and a container, separate from/independent of the analysis module, in which is packed a buffer solution suitable for implementing the immunochromatographic technique.

Abstract: Devices and methods for conducting lateral flow immunochromatographic assays may be used, in some aspects, to measure the level of glutathione-S-transferase pi in a biological fluid collected from a human subject suspected of having had a stroke in order to determine whether the subject has had a stroke or to aid in the selection and administration of a treatment for the suspected stroke. In other aspects, such devices may be used to diagnose, monitor, and/or treat acute respiratory distress syndromes (ARDS), such as the novel coronavirus designated COVID-19.

Abstract: A device for determining the presence and/or amount of at least one analyte contained in a liquid sample, includes a capillary diffusion element (2) materialized on which are a zone (3) for depositing the liquid sample, an upstream release zone (4) and at least two capture zones (5). The device (1) also includes at least one downstream release zone (6) located downstream of at least one of the capture zones, which downstream release zone (6) includes at least one detection reagent conjugated to a visible and/or measurable marker; and the detection reagent of a release zone and/or the capture reagent of the additional capture zone(s), located directly downstream of the release zone, are suitable for binding specifically with the analyte and/or for binding specifically with one another, in order to form a complex that enables the determination of the analyte in the liquid sample at the additional capture zone(s).

Abstract: The invention concerns a device for determining an analyte in a liquid sample, comprising: a) a gripping support (1); b) first capillary diffusing means (2) integral with the gripping support (1) comprising a downstream zone (2a) accessible to external observation; c) a set of predetermined reagents for detecting and/or quantifying the analyte; d) a member for collecting (4) the liquid sample mounted on the support (1). The invention is characterized in that the member for collecting (4) the liquid sample is mounted mobile or fixed on the support; second capillary diffusion means (41) extends from a zone collecting (41a) said sample, to a zone transferring (41b) the latter; and an upstream zone (2b) of said first capillary diffusion means (2) is arranged to be urged temporarily to constitute continuous capillary flow with the second diffusion means (41) transferring zone (41b), when the collecting member (4) is in the retracted position.
