Abstract
A method for measuring immature granulocytes in a blood sample is described. The method includes the steps of lysing red blood cells of a blood sample with a lytic reagent, analyzing the sample mixture by DC impedance measurement, determining immature granulocytes from obtained DC histogram, and reporting immature granulocytes in the blood sample. The method further includes measuring nucleated red blood cells in the blood sample.
Claims11
A method of measuring immature granulocytes comprising steps of:
- (a) mixing a blood sample with a lytic reagent to lyse red blood cells, and to form a blood sample mixture;
- (b) analyzing said blood sample mixture by a DC impedance measurement, and obtaining a blood cell distribution of said blood sample mixture from said DC impedance measurement;
- (c) determining immature granulocytes from said blood cell distribution obtained in step (b);
- and
- (d) reporting immature granulocytes in said blood sample.

A method of concurrently measuring immature granulocytes and nucleated red blood cells comprising the steps of:
- (a) mixing a blood sample with a lytic reagent to lyse red blood cells, and to form a blood sample mixture;
- (b) analyzing said blood sample mixture by a DC impedance measurement, and obtaining a blood cell distribution from said DC impedance measurement;
- (c) determining nucleated red blood cells and immature granulocytes from said blood cell distribution obtained in step (b);
- and
- (d) reporting nucleated red blood cells and immature granulocytes in said blood sample.
