Evaluation the performance of the body fluid mode on the automatic analysis system-XT-4000i / 重庆医学

ABSTRACT

Objective To evaluate the performance of the body fluid mode on the automatic analysis system-XT-4000i .Methods XT-4000i analyzer was used to detect the precision ,accuracy ,carryover rate ,meanwhile to validate the detection limit of the pa-rameters(WBC and RBC) .Results The range of the precision for WBC-BF was 0 .90% -5 .54% ,for RBC-BF was 1 .13% -5 .13% .The carry over rates were 0 .09% for WBC and 0 .14% for RBC ,respectively .As for as the analyzer range ,the results of the linearity and the detection limit verification were in line with the requirements of the analyzer ;the comparison between the man-ual microscopy results and the analyzer results meet the requirements of XT-4000i analyzer .Conclusion The performance of XT-4000i analyzer is in line with the requirements of the instrument range ,which can be used for clinical body fluid analysis and detection .
