    摘要： A visual blood glucose test strip has two membranes that each incorporate a reagent that reacts with glucose in a blood sample applied to the membranes to cause a color change. One of the membranes also includes an inhibitor and a dye. A blood sample applied to the strip causes the two membranes to form two different colors. Comparing the colors to a calibrated color chart permits a user to determine the glucose concentration in the blood sample.

    摘要： A test device and method for determining the presence or absence of an analyte in a fluid sample, the test device including a support bearing a mark thereon, and a matrix defining an axial flow path. In operation, an observation area in the test device becomes transparent, thereby allowing the user to view a mark that is present on a support that is disposed beneath the observation area. Typically, the mark on the underlying support is configured as a minus (null) sign. In the absence of analyte in the sample, the test device presents a negative result as a minus (null) signal. In the presence of analyte in the sample, however, the mark operates in concert with a perpendicular test line on the observation area to present a positive result as a plus (null) signal that is visible to the user.

    摘要： A device for collecting, testing and transporting a liquid specimen of urine or the like incorporates a cup or container and a cooperating lid which becomes sealed about its upper rim when the lid is mated with the specimen-containing cup. An upwardly open subchamber of defined volume, formed in the bottom wall of the cup, is sealed by engagement with a downwardly extending hollow plug portion of the lid that has a bottom wall containing a central aperture closed by a frangible sheet material seal. When initial testing is to be conducted, an elongated assay cartridge is inserted vertically downward through the hollow plug. The bottom end splits open the frangible seal and enters into the subchamber containing the defined volume of the liquid sample, which becomes totally absorbed by a pair of elongated nitrocellulose strips, along which the liquid moves by capillary action to effect the assay tests.

    摘要： A thermochromic polymer-based temperature indicator composition which comprises a polythiophene and a carrier medium. The composition is characterized in that the polythiophene is present in the medium in an amount of about 0.05 to about 5.0% by weight based on the total weight of the composition. The structure of the compound is designed such that when the composition is placed in a heat-exchange relationship with an article, the composition will exhibit a color change when a design temperature or a temperature beyond the design temperature is reached in the article.
