North West London Pathology (NWLP) is one of the UK’s largest diagnostic networks – processing 65 million tests a year across seven hospitals and 280 GP practices. At that scale, consistency at the point of sample collection is critical.
However, variation in how blood cultures were being collected was creating real clinical pressure. Differences in practice and pack quality were increasing the likelihood of contamination and false positives, driving repeat sampling and adding avoidable workload for already stretched clinical teams.
The knock‑on effect was slower, less reliable diagnostics in pathways where speed and accuracy matter most.
A partnership focused on removing variation
RDi partnered with NWLP to address this challenge by introducing a single, standardised approach to blood culture collection.
Together, we designed and implemented a fully regulated, CE‑marked, ANTT‑aligned blood culture collection pack, which has been deployed across all Trusts. This has brought every ward onto the same safe, repeatable workflow and supported clinicians with a system designed to remove any uncertainty at the point of collection.
This ensures consistent, repeatable practice across A&E, ITU and acute wards, removing variation before a sample ever reaches the laboratory.
Our blood culture collection packs are medical‑grade and fully standardised, with end‑to‑end digital traceability built in to support governance and compliance. Designed to be clinician‑ready, the packs enable faster, more efficient workflows while being supported by a resilient, compliant supply chain.
The impact: Faster, safer, more reliable diagnostics
Removing variation from blood culture collection strengthens diagnostic reliability at scale by supporting:
- Fewer contaminated samples and false positives
- Reduced repeat sampling and waste
- Faster, more dependable diagnostic results
- Greater clinical confidence across teams
- Full traceability supports stronger governance and oversight across the pathway
A modern approach to diagnostic quality
The RDi x NWLP collaboration is a working example of how NHS organisations and health‑tech partners can work together to improve sample collection quality, reduce risk and support safer patient care.
