Abstract: The present disclosure relates to devices and methods for detecting the presence of a target analyte in a fluid sample using an assay.

Abstract: An analysis system comprises a sampling cartridge (11) comprising a housing (21, 22) having an inlet (23) for receiving a fluid sample, a sensor (26, 45), and a guide (40, 42) extending between the inlet and the sensor for guiding sample into contact with the sensor. The system also has an optical detection reader (13) for optically inspecting the sensor. The cartridge housing has an inspection window (34) and the reader (13) comprises a socket to receive the cartridge (11), and an optical system (1183, 1186) for inspecting the sensor through the window. The cartridge comprises parallel microfluidic channel (42) for flow of sample from the inlet into contact with the sensor. The sensor comprises discrete sensor pads (45) in at least one channel, with an antibody, an antigen, or molecular imprinted polymer. The channels are of microfluidic size, having a cross-sectional area in the range of about 0.3 mm2 to about 5 mm2. At least one channel comprises a reagent pad (43) upstream of the sensor (45).

Abstract: The present disclosure, among other things, describes a reader system for analyzing one or more analytes in a fluid sample, comprising a casing (204) with at least one port (201) leading to a holster (301) which is configured to receive a cartridge (107) comprising a vertically oriented immunoassay device for analyzing one or more analytes in a fluid sample, an optical system (121) with excitation optics comprising a light source (302) and an excitation lens (305) configured to transmit light from the light source (302) and thereby excite a region of the vertically oriented immunoassay device when a cartridge (107) is placed in the holster (301), and collection optics comprising a photosensor (306) and a collection lens (307) configured to collect emitted light from the vertically oriented immunoassay device when a cartridge (107) is placed in the holster (301), an electromechanical motor system (106) configured to move the holster (301) in a vertical direction with respect to the optical system (121) so that
