Abstract

Objective To investigate the application of UF-100 full-auto urine sediment analyzer in detecting cylindruia. Methods 836 specimens with cylindruia were selected. All the specimens with Pro≥1 + were dectected by chemical dipstick or cylindruia by urine sediment analyzer. The cast were detected by urine sediment analyzer and microscope,and the results were compared. Results Of 836 specimens,320 positive samples( 38. 28% ) were found by UF-100 while 195 ( 23. 33% ) were found by microscope. False positive rate and false negative rate of UF100 were 26. 52% and 23. 08%. Compared the results of urine sediment analyzer with microscope,the difference was statistically significant ( P 0. 01). Conclusions UF100 can detect urinary cast quickly,but there is a little high false negative rate. So we should consider urine sample whether to be detected by microscope compared with results of UF100 and chemical dipstick.
