title: [Evaluation of Clinitek in the screening and optimisation of the diagnosis of urinary tract infection].
abstract: A study was conducted to compare the interest of using Clinitek and leucocytes esterase, blood, nitrites strip Multistix-8 SG (Ames-Bayer Diagnostics) with conventional method (dilution of urine in agar plate) and with automated system (Autobac) as a screening procedure to detect significant bacteriuria. The results are expressed in terms of sensitivity, specificity, predictive value of a negative and positive test. A total of 1303 urine samples were tested of which 730 (56%) were founded negative with Clinitek or conventional urine analysis (Se = 83.6%; VPN = 89.6%). Criteria for urinary tract infection were present for 193 samples (14.8%), the predictive value of a negative test for leucocytes, blood or nitrites (99.6%) justifies the use of Clinitek for economical screening of urine. Overall agreement is higher with the results or Clinitek (in few seconds) than with the Autobac (in 4-5 hours) when compared to the conventional method. The authors propose Clinitek as an effective method for screening and optimised urine analysis for urinary tract infection.
