  • Publication number: 20040166552
    Abstract: Compositions, methods, devices and kits for use in the calibration of coagulation tests. The control compositions comprise particles capable of aggregating in plasma and calcium ions which, when mixed with plasma, simulate the behavior of whole blood in a coagulation test. The methods comprise providing calcium ions and particles capable of aggregating in plasma, combining the particles and calcium ions with plasma to form a control composition, and applying the control composition to a coagulation test. The devices comprise a container having at least two compartments, with one compartment including particles that promote or induce aggregation of a protein or proteins in plasma, and the other compartment includes a solution of calcium ions. The kits comprise a control composition comprising a container of calcium ions, a container of particles capable of inducing aggregation of proteins in plasma, and one or more coagulation test devices.

  • Publication number: 20040109790
    Abstract: A fluidic medical diagnostic device-permits measurement of analyte concentration or a property of a biological fluid, particularly the coagulation time of blood. The device has at one end a sample port for introducing a sample and at the other end a bladder for drawing the sample to a measurement area. A channel carries the sample from the sample port to the measurement area, and a stop junction, between the measurement area and bladder, halts the sample flow. The desired measurement can be made by placing the device into a meter which measures a physical property of the sample—typically, optical transmittance—after it has interacted with a reagent in the measurement area.

  • Patent number: 6521182
    Abstract: A fluidic medical diagnostic device permits measurement of analyte concentration or a property of a biological fluid, particularly the coagulation time of blood. The device has at one end a sample port for introducing a sample and at the other end a bladder for drawing the sample to a measurement area. A channel carries the sample from the sample port to the measurement area, and a stop junction, between the measurement area and bladder, halts the sample flow. The desired measurement can be made by placing the device into a meter which measures a physical property of the sample—typically, optical transmittance—after it has interacted with a reagent in the measurement area.
