    摘要: Systems and methods are provided for determining the age of cellular hemoglobin in individual red blood cells in a blood sample by determining the percentage of HbA1c. In embodiments, a method includes measuring side scatter and fluorescence of the individual red blood cells and identifying immature red blood cells and mature red blood cells from the side scatter and fluorescence measurement. In embodiments, data collected includes the exact number of red blood cells, the fraction limits in fluorescence and side scatter units, the mean value of each fraction in fluorescence and side scatter units, the mean FL1 values per fraction in arbitrary units and the mean side scatter values per fraction in arbitrary units. In embodiments, a method also includes deriving a HbA1c content from the measured mean fluorescence of the individual red blood cells and determining the percentage of HbA1c from the HbA1c content and the hemoglobin content of the red blood cells.

    摘要: A reference control for cell by cell analysis on flow cytometric analyzers contains cellular analogs made of permeated blood cells containing therein aggregated intracellular proteins and preserved antigenic sites thereof, having cellular membrane permeable to antibodies and a suspension medium. The reference control is frozen after being prepared and thawed prior to use. The cellular analogs further contain a fluorescence marker therein. Further disclosed are a method of making the reference control and a method using the reference control, as an internal or stand-alone control, for measurements of cellular hemoglobin and cellular hemoglobin variant of a blood sample.
