Performance evaluation of automatic biochemical analyzer by national standards / 国际检验医学杂志

ABSTRACT

Objective To perform the performance evaluation on the automatic biochemical analyzer with the national standards (YY/T0654-2008).Methods The stray light,absorbance accuracy,absorbance stability and repeatability,absorbance linearity, sample carrying contamination rate,sampling accuracy and repeatability,repeatability of TP,ALT,BUN,etc.in the ADVIA 2400 automatic chemical analyzer were detected according to the national standard(YY/T0654-2008).Results The stray light detection value of the ADVIA 2400 analyzer was 6.2Abs;the error of absorbance accuracy was 0.002 9 and 0.007 5 on the absorbance of 0.5Abs and 1.0Abs;the absorbance stability was 0.000 52;the coefficient variation(CV)of absorbance repeatability was 0.12%;the absorbance linearity range was 0.000 2-3.305 7;the sample carrying contamination rate was 0.1% The sampling accuracy and repeatability conformed to the requirement;CV of repeatability of TP,ALT and BUN was 0.6%,1.2% and 1.2% respectively. Conclusion The measurements of various items of the ADVIA 2400 automatic biochemical analyzer meet the national standard (YY/T0654-2008).
