The current study was undertaken to screen asymptomatic school children in Qalubyia governate, Egypt, and to detect the prevalence of renal disorders using urine dipstick method. Aim of Work The purpose of the study was to determine the prevalence of urinary abnormalities by dipstick test (reagent strips) in asymptomatic school children.

During the first screening by urine dipstick method, 66 (6.6%) children were found to having urinary abnormalities which were further investigated by confirmatory complete urine analysis. Finally 33 were diagnosed having urinary abnormalities. The prevalence rate of isolated hematuria (IH) was 0.9%; isolated proteinuria (IP) was 0.4%; combined hematuria and proteinuria (CHP) was 0.1% and urinary tract infection (UTI) was 1.8% and Glycosuria was 0.1%.
