  • Systems and methods for sample verification
    Patent number: 10650527
    Abstract: The inventive subject matter is directed to point-of-care analytical devices that accurately determine the volume of test samples using image analysis to improve the accuracy of test results performed on the sample. Most preferably, the image analysis is based on rate changes in optical saturation that parallels sample saturation in a porous structure containing the sample.
    Type: Grant
    Filed: September 4, 2015
    Date of Patent: May 12, 2020
    Assignee: Qualigen, Inc.
    Inventors: Michael Poirier, John Stephen Middleton, Suzanne Marie Poirier

  • Whole blood analytic device and method therefor
    Patent number: 9903799
    Abstract: Devices and methods are presented in which a plasma separation device with a first and second portion separates a blood containing fluid. Most preferably, the first portion produces a cell fraction and a plasma fraction, and the second portion captures the plasma fraction. A first actuator then fluidly isolates a portion of the plasma fraction within the second portion, and a second actuator moves the isolated portion of the plasma fraction from the second portion.
