  • Quality control system, analyzer, and quality control method
    Patent number: 7925461
    Abstract: A quality control method using a plurality of analyzers and a control device connected to the analyzers via a network, the method comprising: (a) measuring quality control samples by the analyzers; (b) collecting a plurality of quality control data obtained by measuring the quality control samples; (c) implementing a quality control by the control device based on the collected quality control data; (d) obtaining uncertainty of measurement of analyzer based on uncertainty of analyzer calibration and the quality control data; (e) outputting a result of the quality control; and (f) outputting the uncertainty of measurement is disclosed. A quality control system and an analyzer are also disclosed.
    Type: Grant

  • Method for preparing cells for blood analysis
    Patent number: 4656139
    Abstract: A reagent for blood analysis comprises, as a lysing reagent for leukocyte count, tetradecyltrimethylammonium bromide and/or hexadecyltrimethylammonium chloride, dodecyltrimethylammonium chloride, and citric acid. This reagent is characterized by showing three-peaks fractionation of leukocytes in measuring by means of an automatic blood-analysis instrument. The lysing reagent is used together with a diluent comprising boric acid buffer solution, ethylenediaminetetraacetic acid and (2-pyridylthio-1-oxide) sodium.
