    摘要: A test sheet for the determination of the presence of a substance having peroxidase-like activity in a throw-in-the-bowl fecal occult blood test, includes a specimen test area and a positive control area. The test area has deposited thereon a test ink having at least one oxygen donor reagent and a chromogen reagent capable of being oxidized by the oxygen donor in the presence of blood or a substance having peroxidase-like activity, to provide a visually observable change of color. The test ink also includes a water soluble polymer for immobilizing the chromogen and oxygen donor. The positive control area has deposited thereon the test ink and a substance having the peroxidase-like activity.

    摘要: A test kit for preparing a chemical test pad used in testing for the presence of occult blood in a specimen. The test kit is a foil package enclosing an absorbant pad bearing a peroxygen agent and a solution of guaiac in alcohol in a separate packet or compartment from the absorbant pad. The separate packet or compartment being rupturable by applying hand pressure to the outside of the foil package to mix the peroxygen agent powder on the test pad and the guaiac solution prior to removing the absorbant pad from the foil package. The method relates to performing a medical test by activating a test pad bearing one reagent by applying another reagent thereto while remaining wholly within a protective foil package. According to the method a test pad containing the peroxygen agent is wetted with a solution of guaiac in alcohol prior to removal from the protective foil package and exposure to a specimen of fecal material and water in a test for occult blood.

    摘要: An improved chromogen-reagent test system for a slide, test kit or the like has particular utility in the testing of fecal specimens for occult blood. The chromogen-reagent system may include the use of colorless guaiac which, in the presence of a developing solution and a catalyst, is oxidized to yield a predetermined color such as blue. Hydrogen peroxide is used as the developing solution and hemoglobin in the fecal specimen functions as the catalyst. The chromogen-reagent test system includes an indicator area for determining if the guaiac and the developing solution are functioning properly, i.e., the test system of the present invention verifies that the guaiac has not lost its activity nor been improperly catalyzed and that the hydrogen peroxide has not lost its activity. The indicator area includes a catalyst which has a greater stability than blood, in respect to adverse environmental conditions, such that a determination can be made if the reagents are functioning properly.

    摘要: An electrophoresis apparatus for automatically performing medical assays includes an electrophoresis platform which cooperates with a gantry assembly. The electrophoresis platform and the gantry assembly are movable along paths that are perpendicular to each other. An applicator assembly includes pipettes which transfer fluid samples from a specimen tray to an electrophoresis plate mounted on the electrophoresis platform. The electrophoresis platform then moves to a position into the gantry assembly, where electrophoresis is conducted to separate the samples into different fractions. The electrophoresis platform then moves beneath a reagent pouring station where a reagent is applied to make the separated fractions fluoresce under ultraviolet light. The electrophoresis platform is then moved beneath the gantry assembly again, and an air knife in the gantry assembly spreads the reagent. After incubation and drying of the electrophoresis plate, the electrophoresis platform and gantry assembly are moved relative to one another while the electrophoresis plate is read with the aid of ultraviolet lamps and a photomultiplier tube mounted in the gantry assembly. The gain of the photomultiplier tube is automatically adjusted and the data gathered is automatically edited to remove background noise. The edited results can be printed or displayed on a video monitor. Techniques for calibrating the electrophoresis apparatus are also disclosed.
