Clinical application of the UF-500i Flow Cytometer in screening the asymptomatic urinary infection of pregnant women

Objective:To evaluate the clinical application of the UF-500i Flow Cytometer in screening the asymptomatic urinary infection of pregnant women.Methods:The leukocytes and bacteria in 500 mid-stream urine specimens of pregnant women were detected and compared with UF-500i.Results:The positive rates of UF-500i and urine culture were 10.4% and 7.6% respectively,and their differences had no statistical significance and kept considerable consistency(Kappa=0.999,P》0.05).The sensitivity and specificity of the UF-500i detection for urinary infection were 88.4% and 96.9% and the positive and negative predictive value were 73.1% and 98.9% respectively.Conclusions:The UF-500i Flow Cytometer in screening the asymptomatic urinary infection of pregnant women is rapidly,convenient and economical,which has good application value,and the urine contamination must be pay attention to.
