发明名称 LYTISCHE REAGENZZUSAMMENSETZUNG ZUR BESTIMMUNG KERNHALTIGER ROTER BLUTZELLEN
摘要 <p>A lytic reagent composition for measuring nucleated blood cells in a blood sample is described. The lytic reagent composition contains a quaternary ammonium surfactant, an ethoxylated phenol, and an ethoxylated alcohol. When mixed with a blood sample, the lytic reagent composition lyses red blood cells and enables a differentiation of nucleated red blood cells from other cell types by DC impedance measurement. The lytic reagent composition can further contain an organic ligand for determining total hemoglobin concentration of a blood sample photometrically. Further disclosed is a lytic reagent system including the lytic reagent composition and a diluent. In addition, a single reagent composition containing salts is also disclosed, which can be used without a separate diluent. The lytic reagent compositions can be used for concurrent measurement of nucleated red blood cells, WBC, and hemoglobin of a blood sample.</p>
