  • Publication number: 20240237974
    Abstract: Various embodiments of a swab device, system, and method are provided for measuring and assessing saliva flow in the mouth of a person. In one embodiment, a system includes a swab device and a measuring device. The swab device includes a handle portion and a swab portion, the handle portion being elongated to extend between a proximal end and a distal end. The swab portion is coupled to a distal portion of the handle portion and is sized and configured to collect saliva from the mouth. The measuring device is sized and configured to measure an amount of the saliva collected with the swab portion, the measuring device including a nesting portion integrated therewith. Such nesting portion of the measuring device is sized and configured to receive the proximal end of the handle portion of the swab device to measure the saliva collected therewith.

  • Patent number: 5308775
    Abstract: The novel analytical devices and methods of the present invention involve dual pathway devices which provide for the confirmation of sandwich or competitive assay results. In a self-confirming sandwich assay, the labeled analyte complex becomes immobilized within a first pathway at an assay capture site to indicate the presence or amount of an analyte in the test sample. In a second pathway, a confirmatory reagent blocks the binding of the analyte or labeled analyte complex to a confirming assay site, thereby confirming that the presence of label in the assay capture site indicates a positive test sample. In a self-confirming competitive assay, a confirmed positive result is one in which the device displays a decrease in signal or no signal at the assay capture site, and the confirming assay site displays a detectable signal.

  • Patent number: 5252459
    Abstract: An indicator reagent, assay method and test kit for determining the presence or amount of an analyte in a test sample, in which the indicator reagent is formed by attaching an organic polymer latex particle, preferably a colored particle, to a specific binding member. The specific binding member can be adsorbed onto or covalently bound to the organic polymer latex particles. The organic polymer latex particles are readily detected by direct visual observation or can be detected and/or measured by appropriate instrumentation.
