Our approach
What we test
Week 1 — Repeats annually
Baseline testing
Blood and urine testing with 50+ biomarkers, tailored to your unique physiology and goals to understand what's actually driving your health and what to do about it.
Week 2 — Repeats quarterly
Vital signs
We provide a blood pressure monitor to track your blood pressure and heart rate during your lifestyle tracking.
Month 6 — Repeats every 12 months
Advanced testing
Key biomarker retesting or additional diagnostics selected by your clinician to sharpen the understanding of your health. May include DEXA, VO₂ max, CGM, and more.
Precision testing, personalised to your context and goals.
Baseline testing
Each panel selected against your intake, history, and goals. No template.
Markers NHS panels miss
ApoB, Lp(a), leptin, cystatin-C, AMH, where the answers live.
Interpreted in context
Every result reviewed by your clinician, alongside your data. Not in isolation.
"My energy was low and my hands and nose were always cold for years. I thought it was just me. Calibre tested my leptin, a hormone the NHS doesn't measure, and traced the pattern back to a hormonal imbalance. They gave me specific strategies. The mystery was solved."

Frequently asked questions

Talk to us, from general inquiries to discussing your health goals.
I've already tried Thriva or Neko. How is Calibre different?
Those services give you data. Calibre is designed to deliver outcomes. That’s why we have personalised blood tests, and assess your lifestyle, health history and wearable data in order to build the complete picture of your health. This is joined up and reviewed by a dedicated doctor who provides you with a holistic health assessment and then builds a plan around the 2 to 3 specific things actually driving your energy and long-term health. Not another dashboard to decode alone.
What if I've already tried more sleep, less caffeine, and supplements?
You're not alone. Most Calibre members have already tried what generic advice recommends. That's why we don't start with generic advice. We start with your specific context and data, find what's actually driving your energy, and build a plan around the 2 to 3 things that matter for your body. The cause of low energy often differs from person to person.
How long until I feel a difference?
Most members report noticeable improvements within 4 to 8 weeks. Meaningful change in your biomarkers typically shows in the first re-test at month 6. Your Energy Score is remeasured every quarter so you can see progress objectively, not just how you feel on any given day. Results may vary and will also depend on you implementing the plan.
Do I need to give up coffee, alcohol, or my current routine?
Maybe. Calibre isn't a restrictive protocol. Your dedicated clinician looks at what you're currently doing and identifies the specific changes that will move your energy for your body. Often it's not what people expect. One member's energy improved by swapping white rice for sweet potatoes. Another's by reducing high intensity cardio. We will show you the full picture and provide you with different choices on how to improve your energy.
What if my results indicate something serious?
Your dedicated doctor reviews every result. If anything requires urgent attention or specialist input, we'll flag it immediately and provide a GP referral letter for onward care. Calibre works alongside NHS care, and is not a replacement for primary or acute care.
Where do I get my blood drawn?
We partner with clinics across London, giving you a choice of locations and flexible appointment slots.
Why £39 a month? What's included?
Everything. Your 50+ biomarker panel, your dedicated doctor, quarterly reviews, five days of lifestyle tracking every quarter, wearable integration, your Calibre Energy Score, your personalised plan, advanced testing where indicated (DEXA, VO₂ max, CGM, hormone panels). No upsells. No supplement commissions. Comparable care assembled separately would cost around £5,000 a year.
My GP said my bloods are normal. Can Calibre still help?
Yes. Standard NHS panels are designed to detect disease, not to identify what's driving your energy or what’s optimal for you. Being within reference range doesn't mean your body is running at its best. Calibre tests specific markers most GPs don't run, including leptin, fasting insulin, Free T3, ApoB, and interprets them in the context of your full picture, so we can find what's driving your energy even when your bloods look fine.
Why is Calibre a membership?
Health isn't a one-off, it's an ongoing journey. Calibre is built around continuous support, regular diagnostic testing, and personalised action plans. This is designed so that you achieve positive health outcomes, improving your energy and protecting against long-term health risks.
What does the first month with Calibre look like?
Here's what to expect, though you set the pace.
Week 1: Onboarding
Complete your detailed health history covering your background, symptoms, lifestyle, and goals
Connect any wearables you use
Book your blood test and lifestyle tracking
Week 2: Comprehensive blood panel
Visit a DocTap clinic in London for a 15-minute appointment to give blood and urine samples
Week 2-3: Lifestyle tracking
Track energy, blood pressure, nutrition, activity, and sleep for 5 days (including a weekend) via the app
This captures essential context that is typically not considered
Week 3-4: Health assessment & personalised plan
Your lab results, lifestyle data, and health history come together in your health assessment
1:1 Clinician call walks you through what's driving your results and where to focus
You receive your first personalised plan, designed to improve your energy
From there, you track your progress in the app. Your clinician and our AI navigator are on hand for support until your first check-in after 3 months.
What diagnostics are included, and how often are they repeated?
Your membership includes two layers of diagnostic testing.
Your annual blood panel covers 50–60 markers across 8 physiological systems, including hormones, fertility markers, and the key drivers of your energy and long-term health. A comparable standalone panel would cost you up to £600, before any clinical interpretation or guidance. This is repeated annually so you always know where you stand.
A six-monthly diagnostic check-in deepens your picture. Your clinician selects the most relevant tests based on how your last six months have gone, whether that means retesting key markers to track progress, or introducing a new diagnostic to sharpen understanding in a specific area of your health. These may include a DEXA scan, VO2 max assessment, continuous glucose monitoring, and more.
How is my blood panel personalised?
Not every marker is meaningful for every person. Some are only relevant given specific health histories, risk factors, or goals. In your onboarding, you'll complete a tailored questionnaire covering your health history, current symptoms, lifestyle, and health goals to determine exactly which biomarkers are included in the panel.
How does Calibre compare with an annual health check?
Annual health checks, NHS or private, test a standard set of biomarkers and hand you a scorecard. After that, you're largely on your own.
Calibre goes further and doesn’t stop at the health assessment:
Deeper diagnostic tests personalised to you, not population averages
Your full story, not just your latest numbers
Causal insight into what's actually driving your health
Personalised plans to improve your energy and long-term health
Always-on care from your dedicated clinician and our AI navigator
How does Calibre compare to a wearable like Whoop or Oura?
Your wearable can tell you something's off, it can't tell you why. Calibre integrates your wearable data with your full health context to give those numbers meaning, and to tell you exactly what to do about them.
We currently integrate with Oura, Whoop, Garmin, and hundreds of other health apps. Integration with Apple Health coming soon.
Who are the doctors and clinicians behind Calibre?
Calibre was co-founded by Dr. Innerhofer, alongside world-class doctors and scientists who care deeply about proactive health. Your dedicated clinicians are fully credentialed and accountable.
Clinical care and interpretation is delivered in partnership with DocTap, a CQC registered care provider.
Does Calibre replace my GP?
No. Calibre is a proactive health membership working alongside your existing care, not a replacement for primary or emergency care. For diagnoses, prescriptions, referrals, or anything urgent, your GP is who you need.
Calibre replaces private GPs or specialists you would consult for proactive health needs.
Is my data secure, and how is it handled?
We are privacy-first by design, and our data practices are built to meet the latest UK data protection and GDPR standards. We follow CQC-regulated policies that apply to UK clinical care providers.
Your health data is only accessible to you and your clinical team. It is not shared beyond that without your explicit consent, except where legally required.
