摘要： A device and method for performing a rapid immunoassay for a biological analyte containing a positive control analyte which is concurrently tested using the same device and immunochemical reaction as the biological analyte. The positive control analyte is non-crossreactive with the biological analyte to be detected and may be an immunogen or a hapten. The device and method permit operators of the test device, particularly non-laboratory professionals, to determine that an assay is performed correctly and that the device is functioning properly, thereby allowing the operator to have confidence in the accuracy of either a positive or negative result. This is particularly important when a positive result is indicated by the absence of color at a test site, which is counterintuitive with many operators and which frequently occurs with a competitive immunoassay.

摘要： A method and device for collection of a stool specimen. Formation of the device occurs in situ by providing a liquid absorbent polymer to water contained in a toilet bowl. The hydrated polymer forms a matrix that is capable of supported a stool specimen deposited thereon. The method and device provides a simple, economical, and less distasteful means for collecting, sampling and evaluating a stool specimen for diagnosis and/or therapy.

摘要： A device and method to detect oxidant adulterants added to a sample to prevent detection of tetrahydrocannabinol and/or tetrahydrocannabinol metabolites. The device and method detect popularly available adulterants such as chromate and nitrite through their reaction with a chromogenic substrate for a peroxidase enzyme. The substrate may be applied to a pad. A change in color in the presence of the oxidant may be detected directly or indirectly. The device and method may be used to detect the presence of any oxidant adulterant and is not specific for only one or a few adulterants added to a urine sample submitted for drug testing.
