Abstract: A reader device includes a camera board, processing circuitry in communication with the camera board, and an interface in communication with the processing circuitry. The camera board is configured to capture image data associated with an output signal area of a biological chromatographic test strip. The processing circuitry is configured to determine, based on the image data captured by the camera board, a concentration of a target analyte in a test sample submitted via the biological chromatographic test strip. The interface is configured to output data indicative of the concentration of the target analyte determined by the processing circuitry

Abstract: A device includes camera hardware configured to capture image data associated with an output signal area of a biological chromatographic test strip, and processing circuitry configured to determine, based on the image data, respective intensities of a control line displayed in the output signal area of the biological chromatographic test strip, a hook line displayed in the output signal area of the biological chromatographic test strip, and a test line displayed in the output signal area of the biological chromatographic test strip. The processing circuitry is configured to determine a relative intensity between the test line and at least one of the hook line or control line using the respective intensities, and to detect, based on the relative intensity, a presence of a target analyte in a test sample submitted via the biological chromatographic test strip.

Abstract: A selective microbial detection device and methods of use are provided. The device includes a water-proof pouch that includes a first wall portion, a second wall portion, and a porous membrane filter disposed in the pouch between the first and second wall portions. The filter membrane divides the pouch into first and second compartments. The microbial detection device also includes an effective amount of a dry nutrient disposed in the first compartment, which contains sodium lauryl sulfate in an amount of 1.75 milligrams or greater per twelve square inches of the first wall portion. A dry, cold water-soluble gelling agent is adhered to the pouch in the first compartment and an absorbent pad is disposed in the second compartment. A sealable sample port provides access to deposit a liquid into the first compartment.

Abstract: A method of detecting Listeria monocytogenes. The method comprises providing a culture device with a selective culture medium and a detection article comprising a first indicator system. The selective culture medium facilitates the growth of Listeria microorganisms. When a Listeria microorganism is detected in a sample contacted with the culture medium, the detection article is contacted with the culture medium to detect Listeria monocytogenes.
