NCT ID NCT07370454

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

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 Results may not be published yet.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.

Summary

This study tested a new diagnostic tool called the Xpert Hemorrhagic Fever test, which looks for genetic material from viruses that cause hemorrhagic fever in blood samples. Researchers used 408 blood samples from donors across the United States, some with fever and some without, to see how well the test could identify infected samples. The goal was to see if the test is accurate enough to be used in real-world settings.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance
Xpert Hemorrhagic Fever test (a diagnostic test that detects viral RNA from blood samples)
What this could lead to
If successful, this test could provide a fast, accurate way to diagnose hemorrhagic fevers, helping doctors identify and respond to outbreaks more quickly.
What could go wrong
This is a completed observational study using stored blood samples, not a real-world outbreak setting. The test's performance in actual patients with active disease may differ.
