    Author: Koeijers JJ, Kessels AG, Nys S, Bartelds A, Donker G, Stobberingh EE, Verbon A.
    Journal: Clin Infect Dis; 2007 Oct 01; 45(7):894-6. PubMed ID: 17806056.
    Abstract:
    For 422 male patients with symptoms indicative of a urinary tract infection, nitrite and leukocyte esterase activity dipstick test results were compared with results of culture of urine samples. The positive predictive value of a positive nitrite test result was 96%. Addition of results of the leukocyte esterase test did not improve the diagnostic accuracy of the nitrite test.
