  • Method to determine a diagnostic indicator of blood sugar condition, and, a liquid chromatographic microcolumn therefor
    Patent number: 4142858
    Abstract: A method to determine a numerical percentage value as a diagnostic indicator of the blood sugar condition of a specific person. A whole blood sample is lysed and introduced into an improved ion exchange resin (Amberlite CG-50, Type II) liquid column for microchromatographic separation of hemolysates. Amounts of hemoglobin species, particularly Hb-A.sub.1a-c, are detected and measured by spectrometric (color) analysis. A mathematical computation using integer factors corresponding to amounts of various hemoglobin species produces the numerical percentage value.

  • Method to determine a diagnostic indicator of blood sugar condition, and, a liquid chromatographic microcolumn therefor
    Patent number: 4142857
    Abstract: A method to determine a numerical percentage value as a diagnostic indicator of the blood sugar condition of a specific person. A whole blood sample is lysed and introduced into an improved ion exchange cellulose (Whatman CM-52) liquid column for microchromatographic separation of hemolysates. Amounts of hemoglobin species, particularly Hb-A.sub.1a-c, are detected and measured by spectrometric (color) analysis. A mathematical computation using integer factors corresponding to amounts of various hemoglobin species produces the numerical percentage value.

    Patent number: 4142855
    Abstract: A method to determine a numerical percentage value as a diagnostic indicator of the blood sugar condition of a specific person. A whole blood sample is lysed and introduced into an improved ion exchange cellulose (Whatman DE-52) liquid column for microchromatographic separation of hemolysates. Amounts of hemoglobin species are detected and measured by spectrometric (color) analysis. A mathematical computation using integer factors corresponding to amounts of various hemoglobin species produces the numerical percentage value.

    Patent number: 4142856
    Abstract: A method to determine a numerical percentage value as a diagnostic indicator of the blood sugar condition of a specific person. A whole blood sample is lysed and introduced into an improved ion exchange cellulose (Whatman CM-52)liquid column for microchromatographic separation of hemolysates. Amounts of hemoglobin species, particularly Hb-A.sub.1a-c, are detected and measured by spectometric (color) analysis. A mathematical computation using integer factors corresponding to amounts of various hemoglobin species produces the numerical percentage value.
