Predictive value (posttest probability) of positive and negative test results of respectively nitrites, leucocyte-esterase (only non-urological patients) and combination of both tests with at least one positive for the diagnosis of bacteriuria or UTI in different settings (for sensitivity and specificity values see Tables 1 to 3).
