Assay cartridges are described that have a detection chamber, preferably having integrated electrodes, and other fluidic components which may include sample chambers, waste chambers, conduits, vents, bubble traps, reagent chambers, dry reagent pill zones and the like. In certain embodiments, these cartridges are adapted to receive and analyze a sample collected on an applicator stick. Also described are kits including such cartridges and a cartridge reader configured to analyze an assay conducted using an assay cartridge.

The present technology is directed to capillarity-based devices for performing chemical processes and associated system and methods. In one embodiment, for example, a device can include a porous receiving element having an input region and a receiving region, a first fluid source and a second fluid source positioned within the input region of the receiving element; wherein the first fluid source is positioned between the second fluid source and the receiving region, and wherein, when both the first and second fluid sources are in fluid connection with the input region, the device is configured to sequentially deliver the first fluid and the second fluid to the receiving region without leakage.

A method of manufacturing a fluidic device includes molding either one of the base member and the valve part with a first mold; and molding the other one of the base member and the valve part with a second mold with respect to the molded base member or the molded valve part.

The present invention relates to analytical testing devices comprising a single channel with micro-environment sensors and methods for assaying coagulation in a fluid sample applied to the micro-environment sensors, and in particular, to performing coagulation assays using a single channel with micro-environment sensors in a point of care test cartridge. For example, the present invention may be directed to a sample analysis cartridge including an inlet chamber configured to receive a biological sample and a conduit fluidically connected to the inlet chamber. The conduit includes a sensor chip including a first micro-environment sensor and a second microenvironment sensor, and a fluid lock valve. The sample analysis cartridge further includes a pump configured to push the biological sample over the first micro-environment sensor and the second microenvironment sensor to the fluidic lock valve such that the biological sample is positioned over the first micro-environment sensor and the second micro-environment sensor.
