EpiSwitch Prostate Screening (PSE), developed by Oxford BioDynamics, is considered a highly promising technology for the UK National Health Service (NHS), but it is not yet subscribed to or part of standard NHS care.

As of late 2025, while not currently mandated, it is highly likely that the NHS will consider adopting it due to recent evidence and high-level recommendations.
Here is an analysis of its likelihood of adoption:
High Likelihood Factors (The Case for Adoption)
Superior Accuracy: EpiSwitch PSE boosts prostate cancer detection accuracy to 94% (compared to 55% for the standard PSA test) and has an unmatched 97% specificity, which is ideal for reducing false positives.
Reduced Costs and Biopsies: A 2025 Prostate Cancer Research (PCR) report concluded that implementing the PSE test could reduce unnecessary MRIs by over 86% and biopsies by 84%. This offers substantial cost savings to the NHS, creating a strong economic case for adoption.
UK Provenance: It was developed through a ten-year collaboration involving Imperial College, Imperial NHS Trust, and the University of East Anglia, making it a "homegrown" technology.
Growing Endorsement: Recent 2025 reporting suggests the PSE test should be "considered in the NHS" and that it is "feasible and effective" to reduce inequalities and save lives.
Available Privately: It is currently available privately in the UK, including at Imperial Private Healthcare.

Barriers to Immediate NHS Adoption
Need for Further Evidence: While studies are strong, they are relatively small, and leading charities like Prostate Cancer UK have suggested more research is needed for large-scale, routine use.
National Screening Committee Approval: Extending it to the general public depends on the NHS National Screening Committee reviewing the test for official screening protocols, a process that takes time.
NICE Approval: It is not yet recommended by NICE (National Institute for Health and Care Excellence), which is typically required for broad NHS adoption.

Summary: EpiSwitch PSE is currently the strongest candidate for upgrading prostate diagnostics in the UK. Given the mounting evidence of its cost-saving potential and high accuracy, its adoption as a "reflex test" (a follow-up test after an initial high PSA result) is highly likely in the coming years.
