At The Wellness a doctor reads every result with you and says what it means for your care, and what, if anything, to test next.
Results that nobody acts on are a known failure in outpatient care. A systematic review of 19 studies found that between 6.8% and 62% of laboratory results were not followed up, and missed results were linked to delayed diagnoses.

Choose The Wellness if you want your biological age read from DNA methylation, with a doctor to go through it with you and a practice to follow up anything it shows.
On 24 October 2026 GlycanAge listed one test at £379, and £341, £322 or £303.20 a test on a subscription every 12, 6 or 3 months. At The Wellness the epigenetic age test is £495, with a call with a doctor to go through the results.
No. A glycan test reads the sugar molecules attached to antibodies. An epigenetic test reads DNA methylation, the chemical marks on your DNA, across more than 900,000 sites.
As an estimate. Repeat tests on the same sample vary, so a trend across tests six to twelve months apart says more than one number, and a doctor reads it beside your blood results and history.
10 Portman Square in Marylebone, London, open 7am to 9pm every day. Our second clinic is at 9 Eccleston Street in Belgravia.
