ABSTRACT
Objective To perform Quality comparative study of urine visible components tests by using Sysmex UF-1000i auto-mated urine analyzer (Sysmex UF-1000i) ,AX-4030 automated urine chemistry analyzer (AX-4030) ,and three kinds of manual opti-cal microscope instrument .Methods Applying the above three kinds of instrumental methods respectively to 2 086 case of RBC , WBC and the CAST test and their positive rate and sensitivity difference were analyzed .Results SysmexUF-1000i ,AX-4030 and microscopic three kinds of instrument detection RBC ,WBC ,CAST positive rates were as follows ,Sysmex UF-1000i:20 .4% 、20 .8% 、6 .4% ;AX-4030 :23 .6% 、16 .5% (no CAST );microscope:15 .2% 、18 .6% 、2 .4% .Among the 3 kinds of tests ,RBC ,CAST detection rate were significantly different (P0 .05) .Conclusion Sysmex UF-1000i and AX-4030 can not completely replace the gold standard manual microscopic examination of urine sediment should be three kinds of methods used in combination to ensure the accuracy of the urine analysis results .
