Repeated infections may lead to the development of renal scarring and end-stage renal dysfunction. Therefore, balancing the choices of UTI diagnostic tools depending on the costs versus accuracy can minimize false results that may subject patients to wrong treatments.Objective: The objective of the study was to evaluate the diagnostic performance of LINEAR cromatest and Laboquick URS 10-T dipsticks against conventional urine culture at Arsho Advanced Medical Laboratory (AAML), Addis Ababa, Ethiopia.Methods: A similar cohort of UTI-suspected patients from our previous study, who were prospectively enrolled from Arsho Advanced Medical Laboratory, Addis Ababa, Ethiopia, were considered for this analysis. Data analysis was performed using SPSS version 26. The sensitivity, specificity, and predictive value of different dipsticks were calculated using culture as a gold standard. ROC curve analysis was also used to determine diagnostic performance. A test with a P-value of 0.7 for both dipsticks.Conclusion: In a setting where there is no access to urine culture, the urine dipstick may be considered an alternative diagnostic tool in the diagnosis of UTIs.Keywords: AUC, dipstick test, diagnostic accuracy, sensitivity, urine culture, UTI
