Multiple markers at the same time
Over 80 markers rather than a short list of individual results, so the whole picture is on the table before any conclusion is drawn.

About Us
Performance Health is a functional bloodwork practice. We help active people over 40 work out why they feel older than they should, and get themselves back, by reading their bloodwork in a way a standard test never does.

What we do
Most people who come to us have been told their bloods are normal. They're still stiff, bloated, foggy or exhausted, and they've started to wonder whether this is just what getting older feels like. We don't think that. We think there's usually a reason, and that it's findable.
A standard blood test checks each marker on its own, against a range built from the general population. We read over 80 markers together, against optimal ranges, and in the context of the person they belong to: their symptoms, their goals and how they live. That's what lets a report explain how someone feels, rather than tell them everything is in range.
Then we fix what's fixable, in the right order. Most people aren't trying to become superhuman. They want to feel like themselves again.
How we read bloodwork
At the centre of every report is the Synergy Patterns® analysis, a method developed by our founder, bloods specialist Lou Nicholettos, over years of complex cases. Patterns across over 80 markers, reading how the markers relate to each other and to the person they belong to. It's unique to Performance Health, and it sits behind every report we produce.
Over 80 markers rather than a short list of individual results, so the whole picture is on the table before any conclusion is drawn.
Ratios, correlations and patterns across markers. This is what picks up the early signs a standard test misses, while every single number still looks fine.
Your symptoms, goals, diet and lifestyle, captured in the Performance Health Blueprint. The same number can mean different things in different people.
We look at how the markers relate to one another and to your symptoms and goals, then explain the findings in plain English.
Our founder
Performance Health was founded by Lou Nicholettos, a Chartered Physiotherapist with an MSc in pain science and 21 years in practice. She owns Cornwall Physio, a multi-award-winning clinic recognised as one of the best in the UK, and the work she has always loved most is the complicated cases: people who'd been round the houses, collected opinions, and still had no answers.
She was one of them. In her late twenties she collected six diagnoses in the space of a few years, each with the same message: medication or surgery and not much else. Studying pain science at the time, it became obvious to her that no single label explained what was happening. Working out the real reasons, and fixing them in the right order, is what got her health back.
That experience is where the Synergy Patterns® analysis came from. Over two decades of complex cases, two master's degrees and a two-year blood chemistry training, Lou wrote her own bloodwork interpretation method: what to read together, which relationships matter, and how to put the findings in the context of the person. It's the method behind every Performance Health report.
