Automated camera-based optical assessment involves color assessment of a physical object using conventional and inexpensive computer hardware such as a smartphone. A specially-configured test card includes a body supporting a reagent pad configured to change to an expected color in response to an enzymatic reaction, and an imaging key adjacent the reagent pad. The imaging key includes color fields including at least one field of the expected color. The hardware captures an image of the test card, and processes the image to identify the reagent pad and color fields, to process a brightness calibration target, to determine color values for the reagent pad and color fields, to calibrate the color values as a function of brightness and/or color by comparison to the brightness and color calibration targets, and to identify a color field most closely matching the reagent pad's color to determine a corresponding test result.

Related methods and systems also are described.

The application discloses a test strip and a method for manufacturing the test strip. The test strip comprises a base layer; an intermediate layer overlaid on the base layer; a blood retaining layer comprising a slit and a blood retaining region fluidly commuted with the slit and overlaid on the intermediate layer; an upper layer overlaid on the blood retaining layer; a reagent disposed on a surface of the intermediate layer and exposed to the slit, wherein there are an expectedly predetermined depth and a measured depth from an interface between the slit and the upper layer to an upper surface of the intermediate layer; and a classification mark representing a compensation factor and disposed on an upper surface of the upper layer or a lower surface of the base layer; wherein the compensation factor is the product of a difference between the predetermined depth and the measured depth and a reciprocal of the predetermined depth.

A test sensor for determining an analyte concertation in a biological fluid comprises a strip including a fluid receiving area and port-insertion region. A first row of optically transparent and non-transparent positions forms a calibration code pattern disposed within a first area of the port-insertion region. A second row of optically transparent and non-transparent positions forms a synchronization code pattern disposed within a second area of the port-insertion region. The second area is different from the first area. The synchronization code pattern corresponds to the calibration code pattern such that the synchronization code pattern provides synchronization of the serial calibration code pattern during insertion of the port-insertion region into the receiving port of the analyte meter.

Systems, methods, and apparatus are disclosed for determining quantitative hormone and chemical analyte results from qualitative test results. An image is taken of an ovulation 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.

Single-use diagnostic consumables for use in performing multiple analyses on a fluid sample are provided. The diagnostic consumables include a first sensing region configured for analysis of at least one analyte in a fluid sample that has been received by the diagnostic consumable. The diagnostic consumable further includes a fluid transport material configured to flow a portion of the fluid sample into a second sensing region fluidically connected to the fluid transport material and configured for performing a second analysis of the fluid sample. Methods for performing multiple analyses of a fluid sample on a single-use diagnostic consumable are also provided.

A test strip includes a substantially transparent substrate and one or more colorimetric test spots on the transparent substrate. Each colorimetric test spot has one or more sensing chemicals chemically attached onto a porous support material. The porous support material has at least one exposed surface configured to absorb a body fluid. The one or more sensing chemicals are configured to change a color in response to a presence of a target drug in the body fluid.
