Could one blood draw be enough to catch dangerous infections?

NCT ID NCT07751575

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 This study
Running, but no longer taking on new participants.
Completed
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 Results may not be published yet.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This status has not been confirmed recently, so it may be out of date.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 study looks at whether taking blood for culture in one go is as good as taking it from two separate spots to find bloodstream infections. Adults with suspected infections will have blood drawn twice: first, a larger sample from one vein, then a smaller sample from another vein shortly after. The goal is to see if the first sample alone catches most of the same germs as the combined samples, which could make testing easier and more comfortable for patients.

What this could mean

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

Active substance
Standardized sequential blood culture collection (diagnostic test)
What this could lead to
If successful, this could show that a single venipuncture is enough to detect most bloodstream infections, reducing patient discomfort and lab workload.
What could go wrong
The study is observational and may not change practice if the single venipuncture misses too many infections. Results depend on the specific hospital setting and patient population.

Study facts

What this study's own registry entry says, in plain language.

Phase

Not a phased trial

Phase numbers describe drug development. The registry uses this when they do not apply, as it does for trials of devices, procedures or behaviour changes, and for observational studies.

Participants

About 3,000 people

The number the study aims to enrol. It can still change while the study runs.

Started

Expected to finish

Jan 2028

An estimate. End dates often move.

Lead sponsor

Other sponsor

The registry's catch-all category, for sponsors it does not file as a company, a government agency, or a research network.

Who can take part

This study's own entry requirements. Only the study team can say for certain whether you qualify.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.

Inclusion Criteria: * Age 18 years or older. * Clinical indication for blood culture collection determined by the treating physician as part of routine care. * Planned collection of peripheral blood cultures during the current diagnostic episode. * Ability to complete the study collection protocol. * Informed consent obtained in accordance with the ethics committee approval and institutional requirements. Exclusion Criteria: * Inability to obtain blood cultures from two separate peripheral venipuncture sites. * A clinical condition in which the treating physician considers the additional blood collection inappropriate or unsafe. * Inability to obtain the intended blood volume because of failed collection or premature discontinuation. * Blood cultures collected exclusively through an intravascular catheter. * Declined consent or withdrawal of permission for study participation or use of study data, where applicable.
