Abstract: Disclosed herein is a method and device for testing an agricultural product for the presence of an unwanted residue including a reader-incubator combination that can utilize onboard motor vehicle systems, such as an onboard microprocessor and onboard power supply.

Abstract: Test strips for the detection of at least one analyte in a sample are shown and described. In one embodiment, the test strip includes a test zone, a control zone and a surface reflectance profile to monitor the test strip continuously until the presence or absence of an analyte is detected. In other embodiments, a lateral flow assay includes a surface reflectance profile to monitor the test strip prior to the detection. The surface reflectance profile may include at least one flow reference area and/or at least one test result reference area. The result is systems and methods to improve the detection of the presence and/or absence of at least one analyte in a sample.

Abstract: This application involves detecting luminescence. Various methods and devices are described that reduce interference of ambient light, including UV radiation, on test results. Such methods and devices include using UV blocking material and covering test components prior to use.

Abstract: Lateral flow assay analysis is shown and described. In one embodiment, the lateral flow assay comprises a surface having a reflectance profile that is adapted to enable monitoring of the assay continuously until the detection of an analyte. In other embodiments, a lateral flow assay system includes an incubator and a reader, wherein the incubator incubates the assay concurrently as the reader generates a test result. Further, an assay measurement apparatus may include an optical detector to perform continuous image detection of the assay to generate a diagnostic test result.

Abstract: A substantially moisture-tight unit for packaging moisture-sensitive items. The unit includes a container and cap. The container has a closed container bottom, a container top, a sidewall extending upwardly from the container bottom to the container top and a fixed surface at, or near, the container top. The unit also includes a cap. The cap has a lid and a moisture impervious layer attached to an inside portion of the lid. The lid can snap onto the container to hold the moisture impervious layer against a fixed surface forming a moisture barrier.

Abstract: The invention features a method of determining whether one or more members of an analyte family are present in a sample. The method makes use of a test zone binder, e.g., a receptor that can bind one or a plurality of analytes within an analyte family, the analytes family defined by similar structural binding sites. Members of an analyte family can have different detection level requirements and, therefore, additional analyte binders can be employed to adjust test sensitivity for a subset of the analytes in the analyte family individually, so that each analyte can be detected only if it is present in the sample above a predetermined threshold.

Abstract: A test device for detecting the presence of a residue analyte in a sample, which test device includes a support strip and a sample-absorbing matrix attached to the support strip. The sample-absorbing matrix has a material for absorbing an amount of the sample. The test device also includes a mobile-phase support for holding a mobile-phase composition. The mobile-phase support is attached to the support strip and in contact with the sample-absorbing matrix. A mobile-phase composition is disposed on the mobile-phase support and has a receptor for binding with the analyte. The mobile-phase composition can be carried in the sample. A stationary-phase membrane is attached to the support strip and has a first membrane end in contact with the mobile-phase composition and a second membrane end. The membrane allows lateral capillary flow of the sample from the first membrane end to the second membrane end.
