Abstract:
Objective In order to compare of consistency of results between URIT‐1500 and AIKELAI AX‐4030 urine drychemistry analyzers and for satisfy the need of urine routine test will choose in the reference range of the optimal urine drychemistry analyzers .Methods During the testing time from March 6 ,2015 to April 4 ,2015 ,random have been collected 378 cleaning midstream urine specimens form Luzhou medical college affiliated hospital were detected by the two kinds of urine drychemistry analyzers in parallel .Positive detection rates of each project were analyzed statistical by chi‐square test and counting accordance rate ,general accordance rate ,and the kappa value completely .Results The percentage of variance difference of specific gravity(SG) between the two analyzers was 0 .564% (<1% );Positive detection rates(P value) of WBC ,BIL ,PRO ,BIL between the two analyzers were<0 .05 ,the results were statistical significantly ;Positive detection rates(P value) of GLU ,NIT ,KET ,URO were>0 .05 ;the general accordance rate of LEU ,GLU ,NIT ,KET ,pH were>90% and BLD ,PRO ,URO ,BIL were>70% .Com‐pletely accordance rate except GLU ,NIT ,KET were>90% and the rest of six projects trend lower than normal rate .The kappa value of LEU ,BLD ,GLU ,KET ,URO ,BIL were>0 .40 and PRO ,pH were>0 .30 .Conclusion There is a poor consistency be‐tween the two kinds of urine drychemistry analyzers in the same test condition .It can not to use two different kinds of analyzers in same hospital and should choosing the optimal urine drychemistry analyzers in reference range need on the basis of the particular situations of hospital .Urine drychemistry analyzers is used only for screening ,and the results should be reviewed by urine sediment microscopy in order to meet clinical needs .
