OBJECTIVE: To evaluate the Sysmex UF-1000i(®) system as a urine screening method for the diagnosis of urinary tract infection, and epithelial cells as a predictive value of contamination in woman of childbearing age.
METHODS: A total of 1730 urine samples were processed using a urine culture as a reference.
RESULTS: With 50 bacteria/μl as a cut-off point, the results were: sensitivity 91.3%, specificity 73.1%, negative predictive value 96.2%. For a specificity of 90% for epithelial cells, the results were: sensitivity 31.0%, positive predictive value 67.0%, negative predictive value 66.0%.
CONCLUSION: The evaluated system is fast and effective. Epithelial cells could be used to predict contamination.
