Calibre found the root cause
I'm happy to say that because of Calibre the mystery (of my health situation) was solved. I don't think it would be possible with any other health service provider. Everyone does a little piece of the puzzle, but no one joins the dots and that is the really key thing.

I finally know where I stand
Calibre has given me a clear picture of my current health profile and what areas I need to work on and what my longer term risks are. I really value the care and insights from Calibre. The team is top notch and I feel that their method will help me reach my goals.

Just the actions that matter for me
It's been a really frictionless way of getting an understanding of where I am at health-wise, and what the biggest blockers are to my long-term goals. For anyone who wants to be healthy long term and actually wants to take some action, this will really help guide you into what are the most meaningful actions for you.

Back to my best energy levels
Calibre helped me a lot to get my energy levels back. Through the lab test, they showed me that my testosterone levels were too low. They explained to me that in this case my body would not be able to recover easily from my every day work as a physiotherapist. I feel much more energised and I have more focus for my work and my family.

Calibre helped me rethink my approach
Calibre takes a fundamentally different approach, starting with understanding what success and health mean to you on the long run, tailoring a personalised plan, and providing the necessary accountability over the following quarter. In my case, I focused on my nutrition and it's been a gamechanger.

Now I have the full picture
Collating all my very fragmented data, pulling it together, and having a doctor review this information as a whole to show me the strengths, weaknesses and opportunities of my health… That was the biggest shift for me.

Calibre is now my all-in one preventative health doctor
For a long time I dreamed of having a group of subject matter experts assessing holistically my health. Every time it was siloed. Now they made it possible, building insights that I’ve never thought about before and focusing on clear actions that I can take to make a difference in my health.

What diagnostics are included, and how often are they repeated?
Your membership starts with a personalised blood and urine lab test covering 50+ biomarkers, selected to build a meaningful baseline for your energy and long-term health.
Every six months, you and your dedicated doctor decide which diagnostic will add the most value. This may mean targeted blood-marker retesting or an advanced test such as DEXA, VO₂ max or CGM. Your full blood and urine lab test is repeated annually.
This cycle continues throughout your membership.

How does Calibre compare with an annual health check?
An annual health check gives you a snapshot. Calibre is built around your trajectory. We decide what to measure, interpret it in the context of your full story, act on what matters and track what changes over time, working towards more energy today and lower long-term health risks.

How does Calibre compare to a wearable like Whoop or Oura?
A wearable can tell you something’s off, but it can’t tell you why. Calibre combines wearable data with diagnostics, lifestyle and your health history to understand what it means for you and what to do about it.

Does Calibre replace my GP?
No. Calibre is your primary relationship for proactive health, working alongside traditional healthcare. We help you understand what’s driving your health and how to improve it over time. When something requires specialist or urgent care, your dedicated doctor guides you to the right service.
