Abstract:
Objective To analyze the comparability and correlation of reticulocyte parameters on the Beckman‐Coulter LH780 (LH780)and Sysmex XN‐1000(XN‐1000)hematology analyzers .Methods 80 blood samples were measured by the two instru‐ments ,the RBC count ,percentage of Ret(Ret% ) ,Ret value(Ret#)and immature reticulocyte fraction(IRF) were analyzed ,and the correlation of Ret% ,Ret# and IRF between two instruments were also analysed .The correlation between percentage of high laser reticulocyte(HLR% ) of LH780 and percentage of middle fluorescent reticulogyte(MFR% )+percentage of high fluorescent reticu‐locyte(HFR% ) of XN‐1000 were compared using two calculation methods of each instrument ,and the application value of HLR%were analysed .Results No significant differences were founded in RBC count ,Ret% ,and Ret# between the two instruments(P>0 .05) ,while there was statistical difference in IRF between the the two instruments (P<0 .05) .The relative deviation coincidence rate of RBC count was 97 .5% ,the correlation coefficent (r) of Ret% ,Ret# and IRF were 0 .912 ,0 .895 and 0 .666 respectively . There were statistical differences and correlations between HLR% and MFR% + HFR% when using calculation method of XN‐1000 and LH780 respectively(r were 0 .666 and 0 .767 respectively ,P<0 .05) .Conclusion The RBC count could meet the matc‐hing requirement ,and the Ret% and Ret # may be highly correlated on the two instruments .While the reference range of IRF should be established in each instrument .
