What the study statuses mean

This study's is highlighted.

Recruitment status, easiest to join first

Recruiting now
This trial is taking on new participants right now.
Not yet recruiting
Registered, but not yet taking participants.
By invitation only
Not open to general applications. Only people the study team invites can take part.
Paused
Paused for now. It may or may not start again.
Ongoing
Running, but no longer taking on new participants.
Completed This study
The trial has finished. Results may not be published yet.
Stopped early
Stopped early, before it reached the end. That can be for many reasons, including safety.
Cancelled
Cancelled before anyone took part.

Expanded access (not trials)

Expanded access
Not a trial. This treatment can be requested outside a study, case by case, for people who qualify.
Expanded access (paused)
Not a trial. The treatment can normally be requested outside a study, but is unavailable right now.
Expanded access (ended)
Not a trial. The treatment could once be requested outside a study, but no longer can.
Approved
The treatment has been approved, so it is available normally rather than through this programme.

When the status isn't known

Details not published
The full record has not been published yet, so there is little to show here.
Status unknown
This status has not been confirmed recently, so it may be out of date.

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.
