  • Publication number: 20100239137
    Abstract: A system for reading an assay includes a camera and a processor. The assay is used as a test for the presence or absence of a reaction between a sample and a reagent. The assay is defined by a test area and a background area. The test area is, preferably, substantially circular with a diameter between about 0.1 mm and about 5 mm. The camera simultaneously captures a two-dimensional image of the test area and the background area. The processor determines a first color response from the background area and a second color response from the test area. The processor then calibrates the second color response according to the first color response and generates a result of the test according to the second color response. The system may also include a uniform field illuminator that provides a substantially uniform level of illumination across the assay.

  • Patent number: 7125711
    Abstract: A microliter liquid sample, particularly a biological sample, is analyzed in a device employing centrifugal and capillary forces. The sample is moved by capillary forces into one or more metering wells which define the amount of the sample to be analyzed in subsequent steps. The defined amount of the sample is transferred from the metering wells to one or more conditioning and reagent wells for measuring the amount of an analyte contained in each metered amount of the sample.

  • Patent number: 7094354
    Abstract: A microfluidic device provides separation of particles in a liquid sample, particularly, separation of a sample of whole blood into its components for further analysis. Separation into red blood cells and plasma occurs within a few seconds after the blood sample has been transferred into a separation chamber with the application of centrifugal force of less than about five times gravity. With the application of greater force measurement of hematocrit is possible.
