  • Systems and methods for collecting, testing and transporting liquid biological specimens
    Patent number: 7458942
    Abstract: A collection system for collecting, testing and transporting liquid biological specimens that limits exposure of a tester to the liquid sample and keeps the collected samples pristine even after exposing some of the sample to test strips. The system includes a collection body for receiving and holding a liquid sample, a lid that is coupled to the body, and a test strip housing. The lid includes a transfer conduit while the test strip housing includes an opening defined within the test strip housing. The transfer conduit and the opening are aligned when the test strip housing is coupled to the lid. When the system is moved or tilted, some of the liquid sample moves through the transfer conduit and the opening into the test strip housing.

  • Non-sugar sweeteners for use in test devices
    Patent number: 7319032
    Abstract: The present invention provides methods, compositions, and kits for rapid detection of analytes in a sample. Surprisingly, it has been found that bulking materials having non-sugar sweeteners effectively enhance chromatographic detection methods by providing component stability and controlled release. Thus, the novel components and methods disclosed herein provide a completely new modality of chromatographic analyte detection.
