A breakthrough NHS trial could transform how doctors identify life-threatening infections such as sepsis and meningitis in children. When a child arrives with a high fever, every minute matters. One of the toughest decisions for clinicians—and often for GPs at the first point of contact—is whether the illness is a simple viral infection or something potentially life-threatening like sepsis or meningitis. Now, NHS England has launched a new national trial of an innovative 15-minute blood test that could make that call faster and more accurately than ever before.
What’s Being Tested
The new test, called MeMed BV, analyses the body’s immune response to distinguish bacterial from viral infections. Instead of detecting specific pathogens, it measures three key proteins that behave differently depending on the infection type, producing a clear result in about 15 minutes.
The trial is running across three leading children’s hospitals in England:
- Alder Hey Children’s NHS Foundation Trust (Liverpool)
- St Mary’s Hospital (London, part of Imperial College Healthcare NHS Trust)
- Great North Children’s Hospital (Newcastle upon Tyne)
Funded through NHS England’s Small Business Research Initiative (SBRI) Healthcare programme, the study will run until March 2026, evaluating how the test performs in real-world emergency departments.
Why This Matters for GPs and Primary Care
Although the pilot is taking place in hospitals, its implications reach far beyond A&E:
- Faster triage and referrals: Clearer diagnosis at the start of a child’s illness could mean fewer unnecessary admissions and more accurate referral decisions from GP practices.
- Better antibiotic stewardship: By distinguishing viral from bacterial infections, the test supports efforts to reduce unnecessary antibiotic use—a key part of tackling antimicrobial resistance (AMR).
- Reduced uncertainty for clinicians and parents: Faster, evidence-based answers help GPs make confident decisions and reduce anxiety for families.
- Easing winter pressures: With demand expected to rise again this winter, innovations like this can support NHS Winter Resilience plans and relieve bottlenecks across urgent and primary care.
Expert Insight
When a child presents unwell, distinguishing between a viral illness and something life-threatening like sepsis is one of our biggest challenges. A reliable test that gives us that answer in 15 minutes could be revolutionary.
Dr Kate Jones, Consultant in Paediatric Emergency Medicine at Alder Hey, underscores the transformative potential of this technology. NHS England believes this innovation could bridge the gap between rapid hospital care and safe community management, paving the way for faster, more consistent decision-making across the system.
What’s Next
Results from the trial are expected in 2026, when NHS England will review whether to roll out the technology more widely. If successful, the MeMed BV test could one day be used in GP surgeries, urgent treatment centres, or even community clinics—offering near-instant results for children presenting with fever or infection.
A Reason for Optimism in Primary Care
In a landscape where GPs are under immense pressure, tools like this bring hope. They remind us that innovation is not just about new hospital technology—it is about empowering front-line teams to make better, faster, safer decisions for the patients who need them most.
