Abstract:
Objective To compare the differences of platelet(PLT) count between the optical method (PLT‐O) and electrical impedance method (PLT‐I) ,using microscopic method (PLT‐M) as a standard method ,and to analyze the alarm information of in‐strument .Methods Both of PLT‐O and PLT‐M of 468 cases of patient specimens were detected by Sysmex XE‐2100 automatic hematocyte analyzer ,and which were compared with PLT‐M .The counts and morphology of red blood cells and platelets were de‐tected by microscopic method .The alarm information of red blood cells and platelets were recorded .Results In non‐hematopathy group ,there was no significant difference among PLT‐M ,PLT‐I and PLT‐O (P=0 .071) .In hematopathy group ,PLT‐I was signifi‐cantly different from both PLT‐M and PLT‐O (P<0 .05) ,however ,there was no significantly difference between PLT‐M and PLT‐O (P>0 .05) .There were 149 cases occurring platelets alarm and 127 cases occurring red blood cells alarm in hematopathy group , which was consistent with the results of microscopic method .Conclusion When the value of PLT is below the normal reference range ,counting error of PLT‐I is large and the value of PLT should be rechecked or corrected using PLT‐M and PLT‐O .Re‐exam‐ination should be performed when alarm information is displayed .
