Diagnosing UTIs still depends on 1950s-era Petri dish culture tests, which take 2–4 days to produce results, including antibiotic susceptibility testing (AST). With more than half of UTIs now resistant to common antibiotics, this delay leaves patients at risk.
Most suspected cases are never formally tested. Instead, patients are given a “best guess” prescription — and in more than 50% of cases, this initial treatment fails, prolonging discomfort and driving antibiotic resistance, a serious and escalating global threat.
The situation is made worse by frequent sample contamination, which often requires re-sampling and restarts the process from the beginning.
