The performance evaluation on 3 hemoglobin analyzers / 中国输血杂志

ABSTRACT

Objective To carry out the performance evaluation on 3 hemoglobin analyzers-URIT-12,HemoCue Hb301 and CompoLab TS.Methods Verification of inter-run precision,intra-day precision,and correlation of the 3 analyzers using samples with different concentrations.Results The lower values of inter-run precision of URIT-12,HemoCue Hb301 and CompoLab TSoft were 1.46％,1.45％ and 1.32％,respectively,and the median values were 1.43％,0.56％ and 1.49％,respectively.The lower values of intra-day precision were 1.86％,1.62％ and 1.32％ respectively for URIT-12,HemoCue Hb301 and CompoLab TSoft,with the median values of 1.45％,1.95％ and 1.78％ and the higher values of 1.86％,1.74％ and 1.81％.Based on the results of Beckman-Coulter AcT5diff automatic blood cell analyzer,linear regression equation and correlation coefficient was calculated and expressed as y=0.960 2x+3.201 3,R2=0.973 4;y=1.112 1x-6.767 9,R2 =0.990 7;y=1.031 5x+0.634 7,R2=0.980 3,respectively.Conclusion The 3 hemoglobin analyzers have better inter-run precision and intra-day precision as well as good correlation with automatic blood analyzer,and thus can be applied in physical examinations before blood donation.
