    Abstract: Method and assay devices for the detection of the presence or amount of biological material, analyte(s), or microorganism(s) in a sample. The method includes the steps of liquefying the sample (if necessary) and distributing the liquefied sample over the surface of the assay device. The device may comprise an incubation plate, a dip stick device, or other devices. The devices have at least one reagent provided within the devices. Some devices have a generally flat horizontal surface which is divided into a plurality of recessed wells. Others have one or more surfaces with reagent island(s) immobilized thereon. Each well or reagent island is adapted to hold an aliquot of liquid. The wells or reagent islands are sized and shaped, and formed of a suitable material, to hold the aliquot within the well or reagent island by surface tension. Any excess liquid from the liquefied sample is drained from the surface of the device. The method then involves incubating the assay device until the presence or amount of the biological material, analyte, or microorganism is determined.

    Abstract: A self-contained incubator for growth of microorganism kit and methods for use of such a kit are provided. The kit and methods may detect the presence of microorganisms and may utilize a microorganism growth and indicator medium provided in a sample container along with a heat source, preferably generating heat through chemical means, and optionally heat shields, allowing for on-site testing of a microorganism present in a sample. The sample container may also include a removable vessel cap that includes a barrier separating the sample from a material capable of disinfecting the sample, thereby preventing contact of the sample and the material for a desired time period. The vessel cap may also be used independently in other applications.
