Abstract:
Objective To evaluate the analytical performance of Mindray BS‐820 automatic biochemical analysis system used in primary hospitals in Guangzhou area for verifying whether its performance meeting the clinical requirements .Methods Accord‐ing to the EP5‐A2 ,EP6‐A ,EP7‐A2 and EP‐17A files recommended by CLSI and the Pharmaceutical Industry Standard of the Peo‐ple′s Republic of China YY/T0654‐2008 ,the precision ,linear rang ,anti‐interference capability ,sensitivity and carry‐over rate of the Mindray BS‐820 automatic biochemical analysis system were evaluated by adopting 16 routine biochemical items .Results The pre‐cision results of all 16 analyzing items conducted by the Mindray BS‐820 automatic chemical analysis system conformed to the re‐quirements .The results of 15 items showed good linear relation during the testing range (r≥0 .997 9) .In 16 biochemical items ,the anti‐interference capability of TBIL ,TP ,TC ,TG ,LDL ,HDL ,UREA and Ca to bilirubin ,triglyceride and hemoglobin conformed to or were higher than the anti‐interference capability declared by manufacturer ,but among other 8 items ,the anti‐interference capabil‐ity of 3 items was lower than that declared by manufacturer .The limit of blank(LOB) of all 16 analyzing items was less than LOB in the kit instruction .The carry‐over rate of Glu was 0 .02% ,less than 0 .50% .Conclusion This instrument has good precision , sensitivity and low carry‐over rate(0 .02% ) ,the linear range is ideal ,r≥0 .997 9 ,the anti‐interference capability basically satisfies the clinical needs .Therefore this instrument is suitable for the use in the middle‐small scale laboratory department .
