Investigation on the reference interval of platelet-related parameters in different detection systems / 国际检验医学杂志

ABSTRACT

Objective To investigate the reference interval of platelet‐related parameters including mean platelet volume (MPV) ,platelet distribution width (PDW) ,platelet hematocrit (PCT) .Methods Used Sysmex XN‐9000 assembly line and PEN‐TRA 120 hematology analyzer to analysis the venous blood cells for 3 415 cases of 16 to 90 years old physical examination personnel in Mianyang Central Hospital ,the platelet‐related parameters results of 2 718 standard healthy population by screening were statis‐tically analyzed .Results Platelet‐related parameters 95% reference interval (2 .5% -97 .5% ) of XN assembly lineM PV 9 .9-14 . 7 fL ,PDW 11 .2% -24 .3% ,PCT 0 .15% -0 .30% ;Platelet‐related parameters of 95% reference interval of PENTRA 120MPV 8 .4-12 .7 fL ,PDW 13 .8% -24 .8% ,PCT 0 .12% -0 .26% ;comparison between the instrumentsMPV ,PDW ,PCT results showed significant differences (P<0 .05);comparison between men and womenPCT test results of XN assembly line were differ‐ent (P<0 .05) ,MPV ,PDW ,PCT results of PENTRA 120 were different (P<0 .05);comparison between age groupsPCT result of all ages between men and women were different in XN assembly line (P<0 .05) ,in PENTRA 120 ,MPV ,PDW ,PCT results be‐tween ages were different in men (P<0 .05) ,PCT results between ages were different in women (P<0 .05) .Conclusion Each la‐boratory should establish the laboratory supporting biological reference interval of platelet‐related parameters based on different in‐struments ;in practical applications ,should set the reference interval for different gender or age .
