Can a rapid test help doctors pick the right antibiotic faster?
NCT ID NCT07491419
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tests whether a rapid lab test can help doctors choose the right antibiotic sooner for patients with bloodstream infections. About 400 adults with positive blood cultures will be randomly assigned to either the rapid test or standard testing. The goal is to see if the rapid test leads to earlier, more targeted antibiotic use and better patient outcomes.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- Rapid Antimicrobial Susceptibility Testing (R-AST) diagnostic test
- What this could lead to
- If successful, this could show that rapid testing helps doctors prescribe the right antibiotics sooner, potentially improving recovery and reducing antibiotic resistance.
- What could go wrong
- This is an early-stage diagnostic study, not a treatment trial. The tests may not speed up care or improve outcomes in real-world hospital settings.
