    摘要： Rapid lateral flow immunoassays have an extensive history of use in both the clinical and home settings. These devices are used to test for a variety of analytes, such as drugs of abuse, hormones, proteins, urine or plasma components and the like. The present invention provides an improved procedural control that indicates to the test user that at least a portion of the applied sample has passed through the test result zone of the test strip, and optionally that the test is complete and the test results may be read.

    摘要： The present disclosure includes but is not limited to a device for collecting samples, especially liquid samples to be tested for the presence of an analyte, especially for drugs of abuse, antibodies, antigens and biological moieties such as steroids and glucose. In particular, the disclosure describes improvements in collection device design that provide a simple, non-invasive, non-hazardous method of collecting samples from a subject or patient, especially liquid samples such as saliva, oral fluid and urine. The collected sample can be stored in the disclosed device and the device can be used to apply, in a drop-wise manner, an aliquot of the sample directly to a test device.

    摘要： The present invention is directed novel lateral flow devices for analyzing liquid samples. The devices contain chemical test strips and are useful for testing liquids for physical properties, such as pH, specific gravity, contamination or adulteration, the presence of proteins or blood, and the like. The test strips contain a bibulous material, a filter element, a reagent pad, and in some embodiments also contain a hydrophobic member and a cover. Any fluid can be tested, for example, urine or other body fluids, environmental samples, biological samples, clinical samples, or food and beverage samples.
