Clinical Application of Urinary Sediment Analyzer and Urine Dry Chemical Method Combined Detection

Objective Analysis and discussion on the use of urine dry chemistry analyzer and urine sediment analyzer routine tests of the importance of microscopy.Method Our randomly selected 1200 patients hospitalized patients with the morning urine specimens,respectively by means of UF-100 automatic urinary sediment quantitative analyzer,BW-500 urine dry chemistry analyzer and microscopy three methods detection red,white,compare three methods of test results.Results Automatic urinary sediment analyzer test positive for red blood cells,white blood cells positive 316 cases 178 cases,the red blood cell false-positive rate 8.3%,false negative rate 0,100% sensitivity and specificity 91.7%;Urine dry chemistry analyzer test positive for red blood cells,white blood cells 172 cases 156 cases,the red blood cell false-positive rate 0,false negative rate was 24.56%;Microscopy red blood cells,white blood cells positive positive 228 cases 192 cases.Conclusion Automatic urinary sediment analyzer method and urine dry chemistry analyzer in the detection of red blood cells when there are some false positive and false negative,and in the test cells false-positive rate 0,three methods compared with,so in the use of urine dry chemistry analyzer and urine sediment analyzer test urine,abnormal red blood cells,it is necessary to specimens were microscopy.
