A fluid specimen collection, storage, transport, and testing cup contains a removable chromatographic strip-carrying cartridge and an axially moveable liquid specimen preserving caddy which moves between a first, pre-test position and a second, post-test position. During which a caddy drain is temporarily opened allowing an amount of liquid specimen deposited in the caddy to flow into the cup and contact the strips. Once in the second position, the drain is sealed for later confirmatory testing. The caddy is moved between the two positions by screwing a threaded lid more tightly onto the top opening of the cup. The axial range of the screw is limited by a removable obstruction collar. The caddy can include a liquid specimen containing chamber having a lower opening sealed by a frangible barrier.

The present invention provides an Analyzer adapted to receive an immunoassay cartridge comprising an imaging module including a two-dimensional light sensor and a plurality of light sources. The light sources and the two-dimensional light sensor are arranged such that the light sources are adapted to illuminate a result display section and a graphical code of the immunoassay cartridge and the two-dimensional light sensor is adapted to acquire images of both the graphical code and the result display section. The analyzer comprises an oscillator portion being adapted to cause the immunoassay cartridge to perform oscillations at a pre-set oscillation frequency. The analyzer comprises a processing section adapted to process an image of the graphical code acquired by the two-dimensional sensor to determine the pre-set oscillation frequency. The analyzer comprises a controller adapted to control the oscillator portion to cause the immunoassay cartridge to oscillate at the pre-set oscillation frequency.

A medical diagnostic system is provided to automate analysis of samples to predict a medical condition, such as pregnancy or chronic kidney disease. The system may provide test strip usage automation. The medical diagnostic system may include a sample collection component, collection cup contamination protection mechanism, sample volume control component, test strip reader component, which may be manifested as a lateral flow strip reader, flow reader, sample analytic component, data processing component, data communication component, networked data management component, and device cleaning mechanism. A method to automate analysis of samples to predict a medical condition using the medical diagnostic system is also provided.

Provided is a fluidic device, including: a porous flow path member; an absorbent member contacting the flow path member and configured to absorb a liquid; and a barrier member covering at least a portion of the absorbent member, wherein the absorbent member contains a liquid-absorbent polymer that absorbs the liquid, and a lyophilic polymer having lyophilicity to the liquid.

A test element analysis system for the analytical examination of a sample comprising: at least one evaluation device with at least one test element holder and at least one measuring device for measuring a change in a measuring zone of a test element; at least one barcode reader comprising at least one circuit board having a front side facing the barcode of the test element positioned in the test element holder and a reverse side facing away from the test element, wherein at least one electronic control element of the barcode reader is disposed on the circuit board and wherein the circuit board comprises at least one cavity penetrating the circuit board; at least one camera carrier element; and at least one camera electrically connected to the camera carrier element, with the camera carrier element and the camera being positioned such that the camera observes the barcode through the cavity.

Contamination detection systems, kits, and techniques are described for testing surfaces for the presence of hazardous contaminants, while minimizing user exposure to these contaminants. Even trace amounts of contaminants can be detected. A collection kit provides a swab that is simple to use, easy to hold and grip, allows the user to swab large areas of a surface, and keeps the user's hands away from the surface being tested. The kit also provides open and closed fluid transfer mechanism to transfer the collected fluid to a detection device while minimizing user exposure to hazardous contaminants in the collected fluid. Contamination detection kits can rapidly collect and detect hazardous drugs, including trace amounts of antineoplastic agents, in healthcare settings at the site of contamination.

In one embodiment, a cartridge includes at least one compartment and a reagent in the at least one compartment. The reagent is a chemical composition for testing at least one of soil and vegetation for a chemical contained in the soil or vegetation. The reagent can be used in a soil and/or vegetation analysis test. The cartridge can contain an authentication chip to ensure that the reagent is the correct reagent for the analysis test.

A reader for a lateral flow test device includes a tray or drawer, extendable from the reader, which receives the test device. The tray includes a calibration test pattern affixed or printed thereon placed proximate to the test device and in alignment with the axis of the test device. As the tray is closed and the test device is inserted to the reader, the calibration test pattern is first read by an optics unit including a photodiode. The resulting photodiode output provides a calibration curve S that the reader then uses to correct for any non-linear response of the reader's optical or electronic systems, thus insuring that every reader will yield the same readout for a given test cartridge, despite reader-to-reader variations or reader degradation with time. One use of the reader is for detection of SARS-CoV-2 infection.
