How it works

Understand. Plan. Support. Re-measure.

Everything starts with understanding you. Then we turn what we learn into a plan you can follow, and help you stick with it.

  1. 01

    Understand

    We first get to know your current health, lifestyle and goals, using a video consultation, detailed questionnaires and biomarker testing, together with data you already track, such as grip strength, one-rep max and heart rate variability.

    • Video call
    • Questionnaires
    • Biomarkers
  2. 02

    Plan

    Bringing all of this together, your doctor writes a personalised action plan built around your specific goals, so you know exactly what to do and can follow it in an evidence-based way.

    • Goal-specific
    • Evidence-based
  3. 03

    Support

    Change is hard, especially with a busy life. When you are struggling, your doctor uses coaching techniques to help you build lasting habits, and adjusts the plan as your life changes.

    • Coaching
    • Habit change
  4. 04

    Re-measure

    Repeat testing shows what has changed in your own data. If something is not working, the plan changes.

    • Progress tracked
Why Aeterna

A doctor, not a trend

Questions

Frequently asked questions

Plain answers to the questions we are asked most about longevity care, tests and prices.

What is a longevity doctor?

A longevity doctor is a doctor who focuses on preventing illness and keeping you healthy, strong and independent for longer. At Aeterna Health, that means a detailed assessment, tests chosen for a reason, a personalised plan across nutrition, fitness, sleep, mental wellbeing, relationships and avoiding harm, and regular reviews with the same GP.

What does a longevity assessment include?

Aeterna Live, our lifestyle medicine 360° assessment, includes two 45-minute consultations (90 minutes in total), usually over 4 to 6 weeks. The first is spent understanding you: your history, your goals and what your lifestyle is really like. A general blood panel (cholesterol profile, HbA1c, liver and kidney function, hs-CRP (inflammation), ferritin, vitamin D and vitamin B12) follows, and the second consultation goes through your results and agrees a personalised action plan with you. Your doctor may also recommend further blood tests, a biological age test or physical performance testing, which are priced separately and explained before you decide.

How much does a longevity clinic cost at Aeterna Health?

An Initial Consultation (30 minutes) costs £175. Aeterna Live, our lifestyle medicine 360° assessment with two 45-minute consultations, a general blood panel and a written plan, costs £499. Three-month Focus Programmes (Aeterna Radiant, Aeterna Prevent and Aeterna Perform) cost £2,495 for ten 45-minute consultations (7.5 hours in total), including the general blood panel, and Continuum costs £245 a month for one 45-minute consultation a month. Tests are charged separately and always quoted in advance. Payments can be split into instalments through Stripe.

Who are Aeterna Health's doctors?

Aeterna Health was founded by three GMC-registered GPs: Dr Lwin Mar Than (metabolic health and longevity), Dr Nadia Abuhussein (skin and functional medicine) and Dr Abhinav Vepa (longevity and performance). Each leads their own pathway and all three practise in the NHS.

Do I need a GP referral?

No. You can join directly. With your consent, we share relevant findings with your NHS GP.

Does Aeterna Health replace my NHS GP?

No. Aeterna Health works alongside your NHS care. We are not an urgent or emergency service: for urgent advice call NHS 111, and in an emergency call 999.

Is a biological age test accurate?

A biological age test gives a useful estimate, not an exact age. These tests read ageing-related markers in your blood, such as patterns on your DNA or signs of long-term inflammation; different tests can give different answers, and small changes between tests may be normal variation. We use them for insight and judge progress mainly on established markers such as ApoB, HbA1c, blood pressure, fitness and body composition. Read more about biological age tests.

Is Aeterna Health right for busy professionals and executives?

Yes. Aeterna Health was built for busy professionals, founders and executives, mostly aged 35 to 65, who want to protect their energy, focus and long-term health without taking time out for clinic visits. Consultations are online, plans are designed around a demanding working week, and you see the same GP each time.

Can a doctor help with fatigue, brain fog and bloating?

Often, yes. Fatigue, brain fog and bloating are common and usually have more than one cause, such as poor sleep, stress, diet, gut health, low iron or vitamin B12, thyroid problems or blood sugar changes. Your Aeterna doctor takes a full history, arranges the blood tests that are relevant and builds a lifestyle medicine plan to address the likely causes. Symptoms such as weight loss you cannot explain, blood in your stool or a persistent change in bowel habit should be checked promptly by your NHS GP.

Is there a longevity clinic in London?

Aeterna Health is a UK longevity clinic run by NHS GPs, serving patients in London and across the UK. Consultations take place by secure video, so you can see a longevity doctor around your working day without travelling to a clinic, and blood tests can often be collected at home.

How is Aeterna Live different from an executive health check?

A typical executive health check is a one-off screen with a report. Aeterna Live gives you two 45-minute consultations with a GP: the first to understand your history, goals and lifestyle, and the second to go through your general blood panel results and agree a personalised action plan. You can then continue with a three-month Focus Programme or Continuum, with the same doctor measuring your progress.

Can I message my doctor between appointments?

Yes. On a Focus Programme you can send your doctor one short, non-urgent question a week, and on Continuum one a month. Your doctor replies by voice note or written message within 2 working days on a Focus Programme, or within 4 working days on Continuum. Messages are for quick lifestyle advice, such as a breakfast idea, a sleep tip or adapting your plan while travelling, not for new symptoms, test results or medicines, which need a consultation. If a question is not suitable for messaging, your doctor will say so and it will not count as your question. For urgent advice call NHS 111, and in an emergency call 999. See what to ask.

Can I pay in instalments?

Yes. Payments for any Aeterna Health service can be split into instalments through Stripe, our secure payment provider. The options available to you are shown at checkout.

Can I see an Aeterna doctor online?

Yes. All consultations take place by video, so adults anywhere in the UK can see an Aeterna Health doctor without travelling.

Messaging your doctor

Your weekly question: what to ask

On a Focus Programme you can send your doctor one short, non-urgent question each week (on Continuum, one a month) through our secure platform. Your doctor replies by voice note or written message within 2 working days on a Focus Programme, or within 4 working days on Continuum. Messages are for quick lifestyle advice that can be answered in a couple of minutes, not for assessment or diagnosis.

If a question is not suitable for messaging, your doctor will tell you and suggest the right next step, such as booking a consultation. It will not count as your question for that week.

Good questions to send

  • “What is a quick high-protein breakfast I can have on a busy morning?”
  • “My sleep has slipped this week with travel. Any quick tips to get back on track?”
  • “Can I swap Thursday’s run for a gym session?”
  • “How should I adapt my plan while I am on holiday?”
  • “Is it fine to train before breakfast?”
  • “Which part of my plan should I focus on this week?”

Better in a consultation

  • New, changing or worrying symptoms that need assessing
  • Going through new test results
  • Starting, stopping or changing medicines, or prescription requests
  • Several questions in one message, or questions that need a long answer
  • Anything urgent: call NHS 111, or 999 in an emergency

What is not included. Aeterna Live and all Focus Programmes include the general blood panel. Other laboratory tests, collection fees, prescriptions, medicines, supplements, skincare products and external referrals are charged separately. Their purpose, limitations and full price are explained before you decide. Individual results vary.

Consultations take place online. Prices are introductory and may change before launch. Payment, cancellation and refund terms are set out in our terms and conditions.

Tests explained

What we measure, and what it can tell you

A test is only useful if the result could change what you do next. This guide explains the private blood tests, biological age, gut microbiome, fitness and genomic tests we use, how to read them and where their limits lie. Reference ranges vary between laboratories, so your doctor will always interpret results against your own report and history.

Written and medically reviewed by Aeterna Health's GPs. Last reviewed October 2026.

Unbranded at-home finger-prick blood test kit laid out on linen beside a notebook: private blood tests with Aeterna Health
Many blood tests can be collected at home with a simple finger-prick kit; others need a venous blood draw.

Blood tests

The foundation of every assessment. We choose markers to answer a clinical question rather than running the largest possible panel, and test at the right time of day and cycle so results can be trusted. The tests listed under each heading are examples; many others are available. See every blood test we offer.

Hormones

Including LH, FSH, prolactin, oestradiol, testosterone, thyroid, AMH, and more

Timing matters: men in the morning, women timed to the cycle

LH and FSHSignals from the pituitary gland to the testes or ovaries. Read alongside testosterone or oestradiol, they show whether a hormone problem starts in the gland itself or in the brain's signalling.
ProlactinA pituitary hormone. A raised level can lower libido and testosterone, disturb periods and affect fertility. Stress, some medicines and pituitary conditions can raise it.
Oestradiol and progesteroneThe main female sex hormones. A mid-luteal progesterone (around day 21 of a 28-day cycle) confirms ovulation.
Testosterone, SHBG and free testosteroneIn men, taken fasting between 7 and 11am. British Society for Sexual Medicine guidance treats below 8 nmol/L as low and 8–12 nmol/L as borderline, interpreted with symptoms; a low result is confirmed on a second sample. In women it is measured at far lower levels and read differently.
Thyroid (TSH, free T4, free T3, antibodies)An under- or overactive thyroid can cause tiredness, weight change, low mood and poor concentration, and is common and treatable.
AMHReflects the number of eggs remaining (ovarian reserve) and predicts response to IVF stimulation. It does not predict natural fertility: in women aged 30–44, low AMH did not reduce the chance of conceiving within a year.
And moreThese are examples. Other tests in this group are available, and your doctor will recommend those relevant to you.
Good to know

Following NICE guidance, women over 45 with typical symptoms do not need a blood test to diagnose perimenopause or menopause, because levels swing widely day to day. FSH is useful when symptoms start earlier. Hormonal contraception, illness, poor sleep and heavy drinking all change results.

Metabolic health

Including HbA1c, fasting glucose, fasting insulin and HOMA-IR, liver function tests, ELF test, and more

Fasting blood test

HbA1cAverage blood sugar over the past two to three months. Under NICE thresholds, below 42 mmol/mol is normal, 42–47 is a raised risk of type 2 diabetes (pre-diabetes) and 48 or above suggests diabetes.
Fasting glucoseBlood sugar after an overnight fast. 5.5–6.9 mmol/L indicates a raised risk; 7.0 or above suggests diabetes and needs confirming.
Fasting insulin and HOMA-IRHOMA-IR combines fasting insulin and glucose to estimate insulin resistance, which can develop years before blood sugar rises. There is no single agreed cut-off, so we read it alongside waist size, triglycerides and HbA1c.
Liver function testsALT, AST, GGT, ALP, bilirubin and albumin. Raised liver enzymes are often the first sign of fatty liver disease, which is closely linked with weight, insulin resistance and alcohol, and usually has no symptoms.
ELF test (liver fibrosis)Enhanced Liver Fibrosis is a blood test for scarring in the liver. NICE recommends it for people with fatty liver disease; a score of 10.51 or above suggests advanced fibrosis and warrants specialist referral.
And moreThese are examples. Other tests in this group are available, and your doctor will recommend those relevant to you.
Good to know

These markers respond well to change. Weight, diet quality, activity, sleep and alcohol all move them within months, which makes them some of the most useful measures to repeat.

Cardiovascular risk

Including ApoB, ApoA1, Lp(a), lipid profile, homocysteine, and more

Blood test · fasting not essential, except for homocysteine

Lipid profileTotal, LDL and HDL cholesterol and triglycerides: the standard measures used in NHS risk scores.
ApoBEach particle that can build plaque in the artery wall carries one ApoB protein, so ApoB counts them directly. It can reveal raised risk when LDL cholesterol looks normal. European targets are below 0.65 g/L at very high risk, below 0.80 g/L at high risk and below 1.00 g/L at moderate risk.
ApoA1The main protein in HDL particles. A high ApoB to ApoA1 ratio is linked with higher risk, but raising HDL itself has not been shown to prevent heart attacks, so we use it as context.
Lipoprotein(a)An inherited LDL-like particle that raises the risk of heart attack, stroke and aortic valve narrowing. About one in five people have a raised level. Usually measured once in a lifetime.
HomocysteineAn amino acid cleared with the help of folate, B12 and B6. Raised levels are linked with heart disease and stroke and can point to low B12 or folate. Lowering it with B vitamins has not been shown to prevent heart attacks, so we treat the cause rather than the number.
And moreThese are examples. Other tests in this group are available, and your doctor will recommend those relevant to you.
Good to know

Lp(a) is largely set by your genes, so lifestyle barely changes it. A high result is a reason to manage every other risk factor more closely and to consider testing close relatives.

Vitamins and nutrition

Including Vitamin D, ferritin and iron, B12, folate, omega-3 index, magnesium, and more

Blood test or finger-prick (omega-3 index)

Vitamin DNeeded for bone and muscle health. Below 25 nmol/L is deficient; 25–50 nmol/L may be inadequate for some people. Levels are lowest in the UK from October to March.
Ferritin and iron studiesFerritin reflects iron stores. A level below 30 µg/L confirms iron deficiency, a common and treatable cause of tiredness, hair shedding and breathlessness. Inflammation can raise it falsely.
Vitamin B12 and folateEssential for blood cells and nerves. Deficiency can cause tiredness, low mood, tingling and memory problems, and is more likely with plant-based diets, some medicines and gut conditions.
Omega-3 indexThe proportion of omega-3 fats (EPA and DHA) in red blood cell membranes, a guide to long-term oily fish intake. Higher levels are associated with lower cardiovascular risk in observational studies.
MagnesiumInvolved in muscle, nerve and heart function. Low levels are more likely with some medicines, alcohol and gut conditions.
And moreThese are examples. Other tests in this group are available, and your doctor will recommend those relevant to you.
Good to know

We test nutrients when there is a reason to, then use food first. Supplements are recommended only where a deficiency or a clear benefit has been shown.

Biological age tests

An optional extra that can add insight and motivation, offered with a clear explanation of what it can and cannot show.

Biological age

Ageing and inflammation biomarkers

Simple home sample, such as a finger-prick

What it measures

Biological age tests look at markers in your blood that change as the body ages, such as patterns on your DNA or signs of long-term, low-grade inflammation. From these, they estimate your biological age or how quickly you are ageing compared with your age in years.

Why it matters

People who are ageing faster biologically have a higher risk of chronic disease. Some of these markers have been shown to respond to changes in diet, weight and lifestyle in research studies.

Limits

There is no single gold-standard test, and different tests measure different aspects of ageing, so they can give different answers. Small changes between two tests may be normal variation, and these tests are not used to make clinical decisions. We choose the test that best fits your question, never promise to reverse your biological age, and judge progress mainly on established markers such as blood pressure, ApoB, HbA1c and fitness.

Gut microbiome test

Considered when the result could inform your care, never as a routine screen.

Gut microbiome

Stool DNA sequencing

Home stool sample

What it measures

The bacteria and other microbes in your gut, identified from their DNA, with estimates of diversity and of the functions they may perform.

Why it matters

The microbiome influences digestion, immunity and metabolism. Diet can change it within weeks: in one trial, eating more fermented foods increased diversity and lowered inflammatory markers over ten weeks.

Limits

There is no agreed definition of a healthy microbiome, and an international consensus does not yet support routine testing in everyday practice. A result describes your gut; it does not diagnose disease. It never replaces investigation of red-flag symptoms such as bleeding, weight loss or a lasting change in bowel habit.

Physical performance tests

Three of the strongest measurable predictors of healthy ageing, and among the most responsive to training. Some of the tests we offer are described below, and others, such as strength and grip testing, are also available. Carried out in person at specialist centres.

DEXA body composition

Fat, muscle and bone

Low-dose X-ray scan, about 10 minutes lying still

What it measures

Fat mass, lean muscle mass and bone mass, region by region, including visceral fat stored around the organs.

Why it matters

Weight alone hides what is changing. DEXA shows whether you are losing fat or muscle, which matters for strength, metabolic health and independence in later life. Visceral fat is closely linked with diabetes and heart disease.

Good to know

The radiation dose is very low, less than a standard chest X-ray. A body composition scan is different from the hip and spine scan used to diagnose osteoporosis.

VO₂ max

Cardiorespiratory fitness

Exercise test on a treadmill or bike, with breath analysis

What it measures

The maximum amount of oxygen your body can use during exercise, in millilitres per kilogram per minute: how well your heart, lungs and muscles work together.

Why it matters

Fitness is one of the strongest predictors of long-term survival. In a study of more than 120,000 adults, those with the lowest fitness had around five times the risk of death of those with elite fitness.

Reading the result

VO₂ max falls with age and differs between men and women, so your result is compared with people of your age and sex. Most people can improve it substantially with structured endurance and interval training.

Lung function

Spirometry

Breathing test, about 15 minutes

What it measures

How much air you can breathe out (FVC) and how quickly (FEV1). The ratio between them shows whether the airways are narrowed.

Why it matters

Lower lung function is linked with heart disease and shorter life expectancy, even in people without symptoms. A ratio below 0.7 suggests airway obstruction, as seen in asthma or COPD, and needs further assessment.

Good to know

Lung function responds to stopping smoking and improving fitness, and gives useful context to a VO₂ max result.

Genomics

Your genes do not change, so genetic tests are taken once and only when the answer is useful. Some genetic tests have strong evidence; others are not yet ready for routine use. Examples include the following.

Pharmacogenomics

How your genes affect medicines

Cheek swab or blood sample

What it measures

Inherited differences in the genes that control how your body processes certain medicines, such as some antidepressants, statins, painkillers and blood thinners.

Why it matters

Results can guide the choice and dose of a medicine. In a large European trial of nearly 7,000 patients, genotype-guided prescribing reduced clinically relevant side effects by about 30%.

When we use it

When a medicine with established gene-based prescribing guidance is being started or reviewed. We do not offer it as a general screen for people not taking or starting medicines.

Nutrigenomics

Gene-based diet advice

Cheek swab

What it claims

To tailor your diet to common gene variants, for example for caffeine, carbohydrates or fats.

What the evidence shows

In randomised trials, personalised nutrition advice improved diets, but adding genetic information did not improve them further. Genotype did not predict who lost more weight on a low-fat or low-carbohydrate diet.

Our position

We do not offer broad nutrigenomic panels at present. Personalised advice based on your history, goals and blood results achieves the same benefit. Single-gene "methylation" panels such as MTHFR are not used to diagnose problems or prescribe supplements.

Disease-risk genes

For example APOE, BRCA, familial hypercholesterolaemia, and others

Through the appropriate clinical pathway

What it covers

Genes that change the risk of specific conditions, such as dementia, some cancers or very high cholesterol from birth.

When it is appropriate

When your personal or family history suggests an inherited condition. Results can have major implications for you and your relatives, so testing needs proper counselling.

Our position

We do not include these genes in wellness panels. Where your history points to an inherited risk, we refer you to NHS or private clinical genetics services.

Dr Lwin Mar Than

MBBS, MSc (Microbiology), MRCGP, DipBSLM (Lifestyle Medicine), DipCoaching

Metabolic health & weightSleep optimisationBrain health & cognitionMenopause & midlife healthPreventive longevity medicine

Dr Lwin Mar Than is a GMC-registered GP and London-based metabolic and longevity doctor with nearly two decades of clinical medicine behind her. She helps adults improve their energy, sleep, weight and mental clarity, so they can extend their healthspan, not just their lifespan. Fatigue, weight gain, brain fog and burnout are common, but they are often early signs of changes in metabolism, sleep or hormones that can be found and addressed.

Her approach brings together three skill sets. As a lifestyle medicine physician, she builds every plan on the core pillars of lifestyle medicine: nutrition, physical activity, sleep, stress, relationships and avoiding harm. As a GP with advanced biomarker testing at her side, she looks for the root causes behind each person's symptoms and creates a personalised, evidence-based plan, including medication where appropriate. And as a certified executive and performance coach, she works alongside patients to turn that plan into lasting habits, with repeat testing to show what is changing.

Her work focuses on three biological foundations of long-term health and high performance: metabolism, sleep and brain function. She has a particular interest in women's health in midlife, including how perimenopause and menopause affect energy, weight, sleep, mood and cognition, and she is a certified partner of a national medical weight loss programme.

She qualified in medicine in 2005, completed an MSc in Clinical Microbiology at the University of Nottingham and became a fully qualified GP in 2015. She practises in both the NHS and the private sector, is an associate for the General Medical Council and has mentored doctors through the RCGP mentoring programme. She hosts the Hormones Inside Out podcast, runs monthly menopause webinars and speaks to workplaces on menopause, wellbeing and performance.

Outside the clinic, she founded Leniter Wellness, where she coaches doctors and senior leaders through career and life transitions, drawing on her own experience of building a portfolio career.

Dr Nadia takes a whole person approach, considering how nutrition, metabolic health, hormonal influences, digestive health, sleep and stress may contribute to a person’s concerns. She values thorough assessment, clear explanations and practical plans tailored to each individual’s needs and goals.

Her interest in longevity medicine centres on prevention and helping people maintain their health, physical function and quality of life as they age. She is particularly interested in the role of sustainable lifestyle changes in supporting long term wellbeing.

Through her work at NA*Skin, she combines personalised skin health programmes with regenerative aesthetic treatments, focusing on skin quality, barrier health and natural results. Across her practice, her aim is to help people understand their health and feel confident making informed decisions about their care.

Dr Abhinav Vepa

MRCGP (2023), MBBS (Dist), BSc (Hons) Pharmacology, MAC

Men's healthPerformance & longevityHeart & metabolic riskPreventive health assessmentsBehaviour-change coaching

Dr Abhinav Vepa is a GMC-registered GP and London-based longevity and performance doctor with a decade of experience in clinical practice. He helps men improve their energy, sleep, strength, gut health and hormones, so they can extend their healthspan, not just their lifespan. Low energy, poor sleep, bloating, declining strength and reduced libido are common, but they are not always simply part of getting older.

His approach brings together three skill sets. As a published researcher, he translates the latest evidence into what is most likely to help each individual. As a doctor with a background in pharmacology, he applies it to each patient, using a careful assessment and advanced biomarkers, from biological age to heart and metabolic risk markers, to build a personalised plan, including medication and supplement management where appropriate. And as a certified coach, he works side by side with patients to turn that plan into habits that last, with repeat testing to show what is changing.

His work focuses on the systems that matter most as we age: the brain, heart and metabolism, gut, hormones, and muscles and joints, with a particular interest in men's health and preventive health assessments. Plans are built around six foundations: nutrition, fitness, sleep, mental wellbeing, relationships and avoiding harm.

He studied medicine at King's College London, graduating with distinction alongside a First-Class BSc in Pharmacology, and later earned a Postgraduate Award in Health Economics with distinction from the University of Warwick. He has published 15 peer-reviewed papers, including an award-winning Cochrane review on the Mediterranean diet. He also practises as an NHS GP in London, teaches the next generation of GPs and is invited to speak to workplaces on performance and longevity.

Outside the clinic, he lives by the same philosophy, through strength training, Muay Thai and growing his own fruit and vegetables.
