  • Patent number: 11846637
    Abstract: A device for determining presence or absence of infection due to an infectious agent is described. The device comprises a sample receiving zone configured to receive a liquid sample from a subject suspected of having an infection due to an infectious agent, the sample receiving zone positioned to distribute the sample along a first fluid flow path to a first label zone and along a second fluid flow path to a second label zone. Test lines in each fluid flow path capture a mobile detectable species as an indicator of presence or absence of the infectious agent. The device also comprises a reference line positioned in the one of the fluid flow paths. The bidirectional fluid flow paths emanate from a common sample zone and provide an efficient approach to detection and differentiate two species as indicators of the same infectious agent or as indicators of two different infectious agents.

  • Publication number: 20230243809
    Abstract: Separation of the cellular components of whole blood, or other biological fluid, from plasma or serum can be achieved for assay analysis. A device for facilitating separation can include, for example, a capillary tube that accurately draws target blood volume, a pad that chemically interacts with red-blood cells, such that the red blood cells become chemically and/or physically trapped within pad material, a mechanism for plasma recovery from the pad upon diffusion or active mixing, and a dropper tip that facilitates dispensing the mixture onto a test device. The treatment of the cellular components can be performed prior to contact with a buffer solution, so release of the cellular components into the buffer solution is reduced or prevented. Additional filtration can be provided to filter any remaining cellular components in the mixture.

  • Patent number: 11446654
    Abstract: A substrate structured to define thereon a fluid flow channel and/or a fluid control feature is described. The substrate may additionally comprise a capture zone and/or a test zone, for use as a test strip for determining presence or absence of an analyte of interest, such as an infectious agent or a biomarker. Reagents are deposited in the capture zone and/or test zone as an array of drops.
