title: [Evaluation of the Sysmex UF-1000i automated system for the diagnosis of urinary tract infection].
abstract: 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%.
  
  
  CONCLUSIONS
  The evaluated system is fast and effective. Epithelial cells could be used to predict contamination.
