Abstract:
OBJECTIVE To investigate the value of screening hospital urinary tract infection with UF-100 automated urine analyzer. METHODS It was to count the bacteria and white blood cells in 422 urine specimens with UF-100 as well as to culture the specimens quantitatively.Then the sensitivity and specificity of UF-100 counts and the correspondence of the two methods were evaluated with Yerushalmy mode. RESULTS Compared with the culture results,UF-100 showed a sensitivity of 81.5%,specificity of 63.9%,positive predictive value of 29.1%,negative predictive value of 95.0%,false positive rate of 30.5%,false negative rate of 2.8% and an accuracy of 67.2%. CONCLUSIONS The UF-100 is excellent in analyzing urine specimens,and its bacteria counts can be a valuable indicator in screening hospital urinary tract infection.
