This study's is highlighted.

Recruitment status, easiest to join first

Recruiting now This study
This trial is taking on new participants right now.
Not yet recruiting

Paused for now. It may or may not start again.
Ongoing
Running, but no longer taking on new participants.
Completed
The trial has finished. Results may not be published yet.
Stopped early

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.
