  • Patent number: 8673239
    Abstract: A sample collector and test device is disclosed. The sample collector and test device may be used together as a diagnostic tool for collecting and assay of analytes contained in a sample. A sample collector is also disclosed which may be used with existing sample containers and or test devices. The sample collector may indicate sample adequacy when a sufficient volume of sample has been collected for assay and may also include a sample retaining feature which retains a portion of expressed sample for confirmatory testing, if desirable. The sample collector may also include a mechanism for expressing sample in a sample collector and/or test device. A test device is also disclosed for retaining and assay of an expressed sample. The disclosed test device may be used with existing sample collectors. In a preferred embodiment, test device is used with a preferred sample collector.

  • Patent number: 7858396
    Abstract: A lateral flow test strip for the analysis of a sample featuring numerous capture zones arranged in an array such that each capture zone is substantially equidistant from the sample containing area. The sample does not pass through another capture zone to reach any one of the other capture zones. The capture zones are preferably arranged in a linear array perpendicular to the flow of the sample through the lateral flow test strip. The lateral flow test strip allows for an increased number of simultaneous analyses of numerous analytes from one sample to occur on one lateral flow test strip.

  • Patent number: 5688697
    Abstract: Stabilized microspherical particles having hydrophobic liquid cores prepared as oil-in-water microemulsions. The particles are stabilized by a surface layer comprising an amphiphilic compound and may be functionalized to allow covalent coupling of a ligand to the surface of the particle. When used as tracers in assays, a water insoluble dye may be incorporated in the core liquid of the microparticles.

  • Patent number: 4873126
    Abstract: A system having a coating station comprised of a dispensing assembly and a fluid collection head is useful in a method to precisely coat reagents on porous supports for use in diagnostic devices. In the method, a cover having an aperture therethrough and the porous support secured to its underside covering the aperture is positioned in the coating station between the dispensing assembly and the fluid collection head. The reagent is dispensed from a cannula in the dispensing assembly onto the portion of the porous support exposed through the aperture of the cover. A reduced pressure in the fluid collection head pulls fluid through the porous support. The system is automated by providing a guide channel for holding a plurality of covers in correct orientation and a magazine for holding a stack of covers. An indexing arm delivers the bottom-most cover in the stack to the guide channel and urges covers in the channel along its length.
