Abstract: System and method embodiments for analyzing a test fluid to detect prior or present infestations of bed bugs are described. In an embodiment, the method may include receiving the test fluid on a test strip within the detection device. The test strip may include a reaction portion and a reagent portion containing an antibody or antigen-binding fragment that is conjugated to a colored particle. The test fluid may include bed bug antigen that reacts with the conjugated antibody. The detection device may include a first and a second optical sensor for monitoring a reaction and a background color intensity, respectively. Upon a predetermined time delay elapsing, the detection device determines whether bed bug antigen is present in the test fluid using the monitored color intensities and minimum and maximum color intensity thresholds associated with bed bugs. Then, the detection device outputs a result using a visual display.

Abstract: A method for determining analyte concentration in a body fluid using a mobile device having a camera and a lidar sensor that have an overlapping field of view. In the method, an object is selected and the user is prompted to apply a body fluid sample to a reagent test region. The user is prompted to provide the object within the overlapping field of view of the camera and the lidar sensor. The processor of the mobile device generates a lidar measurement data set representing the object, which is compared to a pre-generated data set. When there is a degree of congruence from the comparison that is above a pre-determined minimum, the camera captures an image of the reagent test region having the body fluid sample applied thereto and concentration of analyte in the sample is determined. When the congruence is below a pre-determined minimum, image capturing is not allowed.

Abstract: Systems, methods, and apparatus are disclosed for determining quantitative hormone and chemical analyte results from qualitative test results. An image is taken of a test device. The image is analyzed to identify a darkness intensity ratio (T/C ratio) between a darkness value of a test-line to a darkness value of a control-line. Additionally, a quantitative substance level may be determined using the T/C ratio, by identifying the type of test device and referencing a data structure that relates quantitative substance levels to T/C ratios for the identified type of test device.

Abstract: A method of evaluating suitability of lighting conditions for detecting an analyte in a sample using a mobile device camera. A test strip is provided for detecting the analyte. A first image of the test strip is captured while an illumination source of the mobile device is turned off and a second image of the test strip is captured while the illumination source is turned on. A sample is applied to the test strip and the first and second images are compared to thereby determine the difference in lighting conditions between the first image and the second image. The comparison is used to derive information on suitability of the lighting conditions for analyte detection. The lighting conditions are indicated as suitable when a predetermined threshold amount of light intensity used for illumination of the test strip originates from the illumination source.

Abstract: Disclosed is a test strip for detecting microalbumin in urine, and more particularly a test strip for detecting microalbumin in urine that contains a synthetic albumin indicator, a buffer solution, a surfactant and a polymer (sensitizer) and thus exhibits high sensitivity. The albumin detection test strip has accuracy sufficient to enable clear observation of color change from colorless to blue through the albumin indicator, and improves the detection limit (increases sensitivity) to thereby enable detection of microalbuminuria at a concentration of 20 mg/L or less. The albumin test detection strip contains a surfactant and a polymer in addition to a synthetic albumin indicator, thereby incorporating separate first and second processes into a single process and having effects of reducing costs, improving processing convenience, and increasing solubility and miscibility.
