Could one blood draw be enough to catch dangerous infections?
NCT ID NCT07751575
First seen Aug 07, 2026 · Last updated Aug 07, 2026
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.

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.
