In a race against old age, early detection is the ultimate advantage. Bespoke health screening is a fast-growing sector in healthcare technology, especially among UHNWs seeking to extend their lifespans and enhance cognitive function and mobility in later life. As demand for these types of tests booms, distinguishing trusted clinics from trend-chasers is key to protecting patients’ long-term wellbeing.
The clinics featured in the 2025 edition of the index offer high-end healthcare services to identify potential health issues years before they become serious, rather than waiting for symptoms to arise. They use longitudinal data collected through regular testing alongside family history, ethnicity and lifestyle factors, to paint a detailed picture of a patient’s risk profile.
‘We’re trying to prevent people who don’t know they’ve got an issue from dying early,’ a medical representative from Primarius Clinic tells Spear’s. Primarius offers a comprehensive range of tests with a particularly well-developed focus on men’s prostate and women’s hormonal health.
Each centre offers a unique combination of tests, but most provide blood analysis covering over 130 biomarkers, cardiovascular assessments, hormone profiling and detailed gut health screening. Technology is ever-advancing in the commitment to provide elite preventative care.

Harley Street’s Lumen Clinic is pioneering in cognitive longevity, offering 3D biometric brain scans known as BrainKey. This advanced scan, introduced to the UK by the clinic, measures brain structure in detail and identifies potential signs of neurodegenerative disease long before symptoms would typically appear. Similarly, Viavi integrates sophisticated blood diagnostics with a holistic health strategy, designed to detect early warning signs and support long-term health optimisation for those suffering chronic illness.
Clients are typically assigned a dedicated team of doctors alongside a concierge service to and from clinics. Physiotherapy and GP services are often also available upon request. ‘Everything is completed on the same day in the same building,’ a Preventicum representative tells Spear’s. Clients begin with a consultation that maps out their existing medical needs, lifestyle factors and wider family history. The day includes blood tests, cardiovascular assessments, hormone profiling and gut health screenings, all completed on-site, with results interpreted by a dedicated medical team.
Often prompted by family history or growing awareness of age-related risks, most clients seek out these clinics in middle age. In the UK, heart disease and cancer remain the leading causes of premature death, and as people’s understanding of lifestyle risks like smoking and alcohol consumption grows, so too does health anxiety. However, with early detection and non-invasive intervention, these risks can be significantly reduced, offering peace of mind.
‘It’s similar to looking after your car,’ says Dr Sabine Donnai, founder of Viavi. ‘You wouldn’t start looking after it once something’s broken. We strongly believe the earlier you start, the more impact you will have on your health.’

Methodology
Each year, the Spear’s Research Unit reassesses and refreshes its rankings of the leading providers in each sector by gathering data from and about the advisers and firms themselves, assessing submission forms, collating nominations, carrying out peer reviews, reviewing data from third-party sources, gathering references and recommendations, canvassing experts and conducting hundreds of interviews.
Advisers are evaluated using a proprietary scoring system that assigns different weightings to certain attributes. These scores feed directly into each new set of rankings in the Spear’s Indices. Each of these indices are published first online (according to the research calendar) and then in print. Print publication takes the form of the annual Spear’s 500 directory, which includes the top advisers in every index.

Each featured adviser is profiled on spears500.com. The site allows users to search the Spear’s database of more than 4,000 entities to find one (or more) to meet their specific requirements by filtering for specific attributes such as an adviser’s location, their specialist expertise and information about their client base.
The best preventative medicine, health screening and anti-ageing clinics: some names to know
Preventicum
- Focus: Early detection and prevention
- Key Contact: Dr Ying-Young Hui
London clinic Preventicum has a team of doctors and consultants who perform and analyse a series of scientifically tuned tests on their clients every 12 months, building an enviable body of data aimed at preventing illness for as long as possible.
‘Everything is completed on the same day in the same building,’ says Dr Ying-Young Hui, who, as the centre’s medical director, is well equipped to cater to his largely international client base. ‘We can offer a prospective client a very detailed consultation with a dedicated doctor at the beginning of their day, going through their concerns, their past history and their family history – anything relevant to their current health, but also potentially what could affect their health in the future.’

Lumen
- Focus: Advanced health assessments
The thorough programme of tests carried out at the Lumen clinic in Harley Street is designed to detect problems that might indicate future risks, such as heart disease or the very early stages of common cancers, so they can be treated as non-invasively as possible.
Dr Garry Savin, an experienced GP, leads the team of dedicated nurses, cardiologists, radiographers and MRI scanning technicians at Lumen who perform the wide range of assessments on offer. He describes the practice as the ‘Rolls-Royce’ of health screening.
The clinic also recently introduced a new technology called BrainKey, Savin tells Spear’s. ‘Basically, we can measure each individual part of the brain with 3D biometric analysis and plot data over time to see if the brain is shrinking too fast … that can be an indication of early neurodegenerative diseases.’

Viavi
- Focus: Proactively managing health
Viavi is a London-based clinic that focuses on preventative medicine and health screening. It was founded by Dr Sabine Donnai, who currently serves as its chief executive. According to Donnai, Viavi’s intention is to ‘give people time, which they often don’t have, and go beyond the obvious to look at underlying drivers rather than just treating symptoms’.
There are different services and memberships to suit clients’ needs: all start with a thorough review of one’s medical history and lifestyle via various diagnostic tests and investigations. Following an assessment to identify any conditions and their root causes, the clinical team creates a ‘health strategy’ for the client. Those who desire it can opt for a year-long or multi-year programme of ongoing monitoring and health management.
In 2025, the clinic introduced a detoxification service aimed at cleansing the blood from microplastics and toxins, reporting that it can help those suffering from chronic fatigue.
