  • Can urine dipstick test be an alternative to detect ...

    Most common organism that was isolated was E. coli (56%) followed by S. aureus (13%). E. coli was susceptible to nitrofurontoin. Conclusion: Urine dipstick could be used as a simple diagnostic test in a limited resource setting for a rapid diagnosis and initiation of empirical antibiotic therapy. Urine dipstick for nitrite has a good specificity.
