Methodology

The Sysmx analyzer counts and sizes red blood cells (RBC) and platelets (PLT) using electronic resistance detection enhanced by hydrodynamic focusing. Hematocrit (HCT) is measured as the ratio of the total RBC volume to whole blood using cumulative pulse height detection. Hemoglobin (HGB) is converted to SLS-hemoglobin and read photometrically.

 

WBC count, differential, reticulocytes (RET) and nucleated red blood cells (NRBC) are all evaluated using flow cytometry with a semiconductor laser exploiting the differences in cell size, complexity and RNA/DNA content. WBC and basophils (BASO) are treated with an acidic lyse that lyses RBC and WBC, but not BASO. The remaining WBC nuclei and intact BASO are differentiated by cell size and internal cell structure. The WBC differential channel classifies lymphocytes (LYMPH), monocytes (MONO), eosinophils (EO), granulocytes, and immature granulocytes (IG) by cellular complexity and nucleic acid content. The differential cell placement is then enhanced using Adaptive Cluster Analysis. Reticulocytes are separated from mature RBC and PLT by size and RNA content. NRBC are separated from WBC based on nuclear size after lysing and DNA/RNA staining.

 

The Immature Information channel (IMI) cytochemically differentiates immature myeloid cells from mature granulocytes based on the membrane lipid content, and direct current and radio frequency technologies.
