Abstract:

Objectives: The present study was undertaken to study the accuracy of TriphenylTetrazolium Chloride (TTC) Test as a screening procedure for detecting asymptomatic bacteriuria (ASB) in school children.

Materials and Methods: A total of 1000 healthy children of both sexes aged between 5 to 14 years were selected from schools of Mysore city. A midstream clean catch specimen of urine was collected and transported immediately to the laboratory. Urine specimens were screened for significant bacteriuria by culture and TTC Test. The results were recorded and calculated for sensitivity of TTC Test.

Results: TTC Test was positive in 39 (3.9%) cases while culture was positive in 11(1.1%) cases. There was a female preponderance among culture positive cases (90.9%). All culture positive cases were positive for TTC Test. The sensitivity of TTC Test was 100%.

Conclusion: TTC Test can be applied as a screening test for bacteriuria due to its high sensitivity in resource limited settings.
