This particularly seems to hold true for test strips. In studies the validity of several urine tests proved to be high. These studies were, however, performed under optimal and standardized conditions. Their results therefore do not reflect daily practice. In this study the validity of urine tests for UTI is determined under daily practice conditions, without the use of a protocol. The results show a validity considerably lower than under optimal conditions. Specificity in particular was lower, even for simple tests like the nitrite reaction. Under daily practice conditions, UTI can neither be confirmed nor excluded sufficiently on the basis of the outcome of a urinary sediment or test strip. © Oxford University Press Original articles nationallicence Winkens Ron AG Diagnostic Coordinating Centre, Maastricht, The Netherlands, Maastricht, The Netherlands, Maastricht, The Netherlands aut Leffers Pieter Department of Epidemiology, University of Limburg Maastricht, The Netherlands aut Trienekens Thera AM Department of Medical Microbiology, University of Limburg Maastricht, The Netherlands aut Stobberingh Ellen E.
