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/¦Ìl 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.
