Abstract
Objective To evaluate the performance of fully automatic urine sediment analyzer Sysmex UF‐1000i in order to discuss whether its performance meets the clinical requirements .Methods The evaluation was per‐formed according to the guidelines established by the accreditation of the laboratory ISO15189 .The within‐batch and inter‐batch precision ,carry‐over contamination rate ,linear range and accuracy of WBC count ,RBC count ,epithelial cell(EC) count ,CAST count and bacterial(BACT) count were analyzed and the biological reference interval was veri‐fied .Results The low level control within‐batch precisions ,high level control within‐batch precisions ,low level con‐trol inter‐batch precisions ,high level control inter‐batch precisions ,low level control accuracy ,high level control accu‐racy of WBC ,RBC ,EC ,CAST and BACT and the carryover contamination rates of RBC (0 .02% ) and BACT (0 .00% )were conforming the requirements of the manufacturer .The linear correlation coefficients(r2 ) of WBC ,RBC and BACT were 0 .999 4 ,0 .999 8 and 0 .999 8 respectively ,which was more than or equal to 0 .95 with good lineari‐ty .Conclusion The various properties of the UF‐1000i meet the demand of ISO15189 ,which could be used in clinical urine sediment detection .关键词
