A testing device for identifying an antigen or antibody within a biofluid sample including: a substrate having a hydrophilic surface thereon; the surface including a collection zone, and at least one detection zone extending therefrom; wherein the biofluid sample can be mixed with a specific antigen or antibody, and deposited on the collection zone and transferred by capillary action to the detection zone; the antigen or antibody in the biofluid sample reacting with an appropriate said antibody or antigen thereby resulting in a visual indication within the detection zone.

IMMUNOCHROMATOGRAPHIC ASSAY DEVICE
20220099668 · 2022-03-31 ·

The present invention relates to an immunochromatographic assay device, comprising: a cover plate; an immunochromatographic assay kit; and a sample loading pad. A wet zone is defined by the cover plate and at least part of a sample loading portion of the sample loading pad disposed close to an installation position of the immunochromatographic assay kit. The height of the wet zone satisfies the following condition: when flowing into the wet zone, a sample solution is driven by capillary action to flow from a surface of the sample loading portion toward the immunochromatographic assay kit. A wet zone having a certain length is arranged in front of a sample loading zone of an immunochromatographic assay kit, such that when a sample solution flows into the wet zone, capillary action drives the sample solution to flow into the wet zone, thereby increasing a flow speed of the sample solution in the wet zone, allowing substantially simultaneous sample loading on immunochromatographic assay kits at different installation positions, and accordingly enhancing the consistency and uniformity of sample loading.

Immunoassay test device with two fluid flow paths for detection and differentiation of two or more analytes

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.
