Under the agreement, S-Thetics offers the test to members of its new programme, and Nightingale Health analyses the blood samples. From a single blood sample, the Nightingale Health Check produces a 10-year risk estimate for five chronic diseases: heart attack, ischaemic stroke, type 2 diabetes, chronic kidney disease, and fatty liver disease. The report also includes the person's Metabolic Age and Metabolic Resilience Score, which can be followed over time.

Each member starts with a baseline test in the clinic and retests over time, so the programme shows whether their health is moving in the right direction rather than giving a single snapshot. Results are reviewed under the clinical leadership of Medical Director Miss Sherina Balaratnam and set within the member's wider clinical picture. The clinic then turns them into a personalised plan covering lifestyle, skin health and, where appropriate, treatment.

S-Thetics was founded in 2015 and has always looked beyond how a patient looks to the health that underpins it. Miss Balaratnam has been a doctor for more than 26 years, including seven years in reconstructive plastic surgery in the NHS and 16 years in aesthetic medicine. The membership brings aesthetic medicine and preventative health together in one clinically led programme.

“For years I have treated the visible signs of ageing, while knowing that how a patient is ageing on the inside matters just as much. The Nightingale Health Check gives us a way to measure that. From a single blood sample, we can help patients understand their metabolic health and where their future risks may lie, then use repeat testing to follow how that picture changes over time. For me, this is a natural evolution of our work at S-Thetics: bringing aesthetic medicine and preventative health together in a way that is personal, measurable and clinically grounded,” said Miss Sherina Balaratnam, Medical Director of S-Thetics Clinic.

“People who come to an aesthetics clinic are already investing in how they age. S-Thetics gives them a way to see how they are ageing on the inside too, under the care of a doctor who reviews every result. With the Nightingale Health Check at the start of the membership and repeat tests along the way, members learn their disease risks from one blood sample and can follow whether the changes they make are working,” said Teemu Suna, founder and CEO of Nightingale Health.

The membership launches at S-Thetics in Beaconsfield in November 2026. More information: sthetics.co.uk
