RESUMEN
Objective To evaluate the performance of UW2000 automatic urine system .Methods Using UW2000 automatic u‐rine system ,to evaluate intra ,inter batch precision ,linear ,carryover ,and the accuracy of the urine visible components(RBC ,WBC);at the same time intra ,inter batch precision and accuracy of of urine dry chemistry component .Results The within‐run coefficients of variation(CV% ) of RBC in high ,middle and low‐value samples were 15 .6% ,6 .8% ,20 .3% ,WBC were 16 .4% ,10 .5% ,24 .6% , respectively .Inter‐run precision of variation(CV% ) of RBC in middle and low‐value were 12 .8% ,13 .2% ,WBC were 15 .3% , 22 .8% ,respectively .The correlation coefficient of RBC was 0 .991 and the linear range was 88-19 513/μL .The correlation coeffi‐cient of WBC was 0 .997 and the linear range was 7-8 254/μL .And carryover rate was 0 .00% for RBC and 0 .06% for WBC ;The coefficient of UW2000 and microscopy on RBC and WBC were 0 .992 ,0 .995 .Within‐run precision ,inter‐run precision and accuracy for urine dry chemical composition of high ,low controls were all within the requirements of standards .Conclusion UW2000 auto‐matic urine analyzer workstation was not only save manpower ,but also with high detection speed and save cost .Importantly ,the re‐sults are reliability .In addition ,it could meet the working requirement in the general hospital ,and has great application value .
