Functional Testing: Blood, Genetic & Gut

Stop guessing what's driving your symptoms. Get real answers with personalised, science-backed testing.

Why Test?

Fatigue, bloating, weight changes, mood swings, brain fog: these symptoms can have dozens of causes, and guessing rarely gets you very far. Functional testing gives you an actual picture of what's happening in your body, so your nutrition and lifestyle plan is built around your own results, not generic advice. Testing can help identify what's behind:

Hormone imbalances and perimenopause symptoms
Gut issues: IBS, bloating, food intolerances, acid reflux
Metabolic health: pre-diabetes, insulin resistance, raised cholesterol

Nutritional therapist reviewing client notes and planning a personalised health plan

Three Ways to Get to the Root Cause

Blood test vial for hormone and health panel testing

Blood Testing

Think of it as a full health MOT: a comprehensive panel of more than 60 markers, going well beyond what's covered in a standard GP blood test. We look at:

Essential nutrients: Vitamin D, B12, ferritin and iron
Hormones: oestrogen, progesterone, testosterone and cortisol
Blood sugar and metabolic markers, including insulin
Cholesterol and cardiovascular markers
Full thyroid panel: TSH, T3 and T4
Liver function markers

Together, these give a genuinely personalised picture of what's driving your perimenopause symptoms, rather than looking at any one area in isolation.

Mouth swab DNA test kit for genetic health testing

Genetic Testing

Using Lifecode Gx, we look at small variations in your DNA called SNPs (genetic mutations), which can influence how your body handles everything from mental wellbeing and gut function to metabolism and hormone balance.

Understanding your unique genetic blueprint means your nutrition, supplement and lifestyle plan isn't generic advice, it's built specifically around how your body is wired to work. The test itself is simple and non-invasive, just a quick mouth swab you can do at home.

At-home stool test kit for gut microbiome analysis

Gut Testing

A functional stool test looking at a wide range of markers across two key areas:

Host markers, your own digestive function, including how well you're breaking down and absorbing food
Microbial markers, your gut microbiome, plus any pathogens or imbalances present

This can help identify the root cause of bloating, reflux, food intolerances, constipation, diarrhoea, IBS, flatulence and other chronic digestive issues, rather than just managing symptoms.
