The aim of this study was to evaluate the diagnostic accuracy of the quantitative C-reactive protein (CRP), erythrocyte sedimentation rate (ESR) and white blood cell (WBC) count in urinary tract infections (UTI) among hospitalised infants and children in Qazvin, Iran. ⋯ Although acute phase reactants can help in the diagnosis of a UTI, they are not pathognomonic. CRP, ESR and WBC were neither completely sensitive nor specific for detecting a UTI and its localisation site in Iranian children. Therefore, in a country where advanced clinical diagnostic tests are available, the advanced test should be used in conjunction with CRP, ESR and WBC analyses. Finally, a combination of laboratory tests along with history and exact clinical examination are needed for the diagnosis of a UTI and its localisation site.
