⸻ TESTING & INVESTIGATIONDiscover the root cause of what's holding you back
Testing over guessing. Functional and clinical testing, used strategically - whether you're navigating midlife symptoms, working to improve performance, or supporting an athlete's recovery - only where it provides meaningful insight.
⸻ My approachLooking beyond standard blood tests.
Standard laboratory testing is designed to identify disease. Many symptoms, whether midlife-related, performance-related, or affecting recovery, arise when systems are under strain but still within "normal" reference ranges.
Functional testing allows us to explore patterns that may not be visible through basic screening markers. It clarifies how different systems - hormones, thyroid, metabolism, gut health, stress physiology - are interacting.
In some cases, careful clinical assessment alone reveals the patterns that explain persistent symptoms. In others, targeted functional testing is what turns a guess into a clear answer.
⸻ Frequently used testsThe tools used - when they help, not by default.
Example test results *
Hormone TestingThe DUTCH test - comprehensive hormone analysis.
A urine-based test offering an in-depth analysis of hormonal health - oestrogen, progesterone, testosterone, and adrenal hormones, including cortisol, DHEA, and melatonin. Hormone imbalances can contribute to fatigue, unexplained weight gain, insomnia, mood changes, fertility issues, and PCOS. The test also assesses organic acid markers, certain vitamins, and neurotransmitter levels - offering a thorough picture of individual hormonal need.
Ultimate Stool AnalysisGI Comprehensive Stool Analysis - a precise look at gut health.
A thorough assessment of digestive health, an essential foundation for wellness. Provides insight into the microbiome - bacteria, yeast, and parasites - and the GI ecosystem, helping uncover chronic patterns that affect energy, mood, skin, and hormone metabolism. It's also relevant for athletes — exercise-induced GI distress, gut symptoms during training or competition, and poor nutrient absorption can all affect performance and recovery, and often trace back to an underlying gut imbalance. Suitable for: IBS/IBD, bloating, neurodevelopment conditions, depression, chronic fatigue, autoimmune conditions, and SIBO.
food intolerances and/or ALLERGIESPremium Food Intolerance Test
Bloating, IBS-type symptoms, brain fog, low energy, or unexplained skin flare-ups can all have a dietary trigger hiding in plain sight. Using a simple at-home finger-prick sample, this test measures your body's reaction to 200 different foods and ingredients, with results back within a week.
It's a useful piece of the puzzle whether you're navigating midlife symptoms that haven't responded to the obvious changes, an athlete whose gut keeps interrupting training or competition, or a young athlete whose performance or recovery doesn't add up despite doing everything "right."
GENETICS & NUTRIGENOMICSDNA insight - understanding the blueprint behind your results.
Using Lifecode Gx, a professional genotype analysis platform, I can look at key genetic variants that influence how your body processes nutrients, responds to exercise, manages hormones, and handles inflammation and detoxification. This isn't about fixed predictions - it's about understanding your underlying tendencies, so nutrition and lifestyle strategies can be built around your biology rather than generic guidelines.
Genetic insight is useful across the board: for women navigating midlife, it can highlight inherited patterns in hormone metabolism and detox capacity; for athletes, it can inform recovery, injury risk, and how you respond to training load; for younger athletes, it offers an early, evidence-based way to personalise nutrition as they develop.
⸻ Testing philosophyTesting is selective and purposeful - never excessive.
The goal is to understand how different systems are interacting. We test where it provides meaningful clinical insight - not for the sake of generating data. The right test at the right time turns guesswork into clarity.
"Testing is never used simply to generate more data. It is used to answer meaningful questions."
⸻ Not sure where to start?Health & Performance Audit
If something doesn't feel quite right - your energy, digestion, recovery, weight, hormones or performance - but you're not sure what needs your attention first, this is a good place to start.
I'll review your health, nutrition, symptoms, training and goals before we meet, then we'll spend 60 minutes looking at the bigger picture and identifying your priorities.
You'll leave with 3–5 clear, personalised actions to start implementing, and, where appropriate, recommendations for further investigation or functional testing.
