New DNA test could beat old method for stubborn UTIs
NCT ID NCT06996301
First seen Jun 26, 2026 · Last updated Jun 26, 2026 · Updated 1 time
Summary
This completed study tested whether a DNA-based PCR test works better than the usual lab culture for diagnosing complicated urinary tract infections (cUTIs) in adults. Over 770 participants across six U.S. sites were randomly assigned to have their treatment guided by either PCR or culture results. The goal was to see which method leads to more patients getting better by day 28, and whether PCR can help reduce unnecessary antibiotic use.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- PCR diagnostic test (DocLab UTM 2.0)
- What this could lead to
- If PCR proves more accurate or faster than standard culture, it could help doctors choose the right antibiotic sooner, reducing ineffective treatment and antibiotic resistance.
- What could go wrong
- The trial is completed but results are not yet reported; PCR may not show a clear advantage over culture, and its higher cost or complexity could limit real-world use.
