Unfortunately, 1950s-era technology using a Petri dish culture test is the current standard to diagnose UTIs. This test takes 2 to 3 days, including an antibiotic susceptibility test (AST) that is required – in part – because antibiotic abuse has resulted in over half of UTIs being resistant to the most common antibiotics.
Worse yet, and especially with pediatric patients where urine collection can be problematic: urine samples are often contaminated, requiring re-sampling and a re-starting of the clock.
As a result, most patients are never tested for a suspected UTI and instead are given a ‘best guess’ prescription, half of which will not be effective and further contribute to the problem of antibiotic resistance.
