    摘要: A method for increasing the throughput, or the precision, or both the precision and the throughput, of a flow cytometer, or of a hematology analyzer employing a flow cytometer, and for further reducing the complexity of such a cytometer or analyzer, by utilizing the technique of laser rastering in combination with a lysis-free single-dilution method. Laser rastering involves sweeping a laser beam across a flowing sample stream in a hematology analyzer. A lysis-free single-dilution method involves performing all the flow cytometer measurements on a sample using a single aliquot, a single lysis-free reagent solution, a single dilution, and a single pass of said dilution through the measurement apparatus. An apparatus suitable for carrying out the method of this invention comprises an optical module comprising a source of light, a scanning device, a lens or system of lenses, a flowcell, detectors, and filters; and an electronic module comprising preamplifiers, analog signal conditioning elements, analog-to-digital converters, field-programmable gate arrays, digital signal processing elements, and data storage elements.

    摘要: A method for determining the value of MCV of a fresh sample of blood when the value of MCV for that sample of blood is known, but the period of time that the sample of blood has been stored is not known. The method of this invention allows an automated hematology analyzer to provide a more reliable indication of the initial value of MCV of a sample of blood, i.e., the value of MCV that would have been expected for the sample of blood when the sample was fresh. Furthermore, the method of this invention uses data that is readily available as part of the blood count data.
