Advanced testing helps work out what’s driving your symptoms. That includes hormone panels, nutritional assessments, and allergy and mould exposure testing.

The four most used

  • DUTCH hormone test: Your hormones, how your body breaks them down, your stress response and your sleep patterns, all in one test.

  • Microbiome test: How your gut is doing, including digestion, inflammation and what your diet and gut bugs are up to.

  • SIBO breath test: Checks for bacterial overgrowth in the small intestine, a common cause of bloating and gas.

  • Continuous glucose monitoring: A small sensor tracks your blood sugar through the day, so we see how your food, sleep and stress affect your energy.

A range of functional tests are available to assess your health in-depth.

Advanced Dried Urine Hormone Analysis (DUTCH Test)

The DUTCH Test is one of the most advanced methods for assessing hormone metabolism, adrenal function, and circadian rhythm regulation. Unlike standard blood tests, it offers a comprehensive, non-invasive analysis of hormone production, metabolism, and elimination—ideal for those experiencing symptoms despite normal lab results.

Who Should Consider This Test?

It’s particularly beneficial for those struggling with:

  • Hormonal Imbalances: PMS, irregular, heavy periods, or perimenopausal symptoms

  • Metabolic & Skin Issues: Weight gain, low libido, hair loss, or acne

  • Stress & Mood Concerns: Chronic stress, fatigue, mood disorders, or sleep disturbances

  • Cyclical Symptoms: Headaches, migraines, fatigue, weight gain, mood swings, depression, anxiety, brain fog, or poor memory recall

What the DUTCH Test Measures

  • Cortisol & Stress Response: Tracks cortisol patterns over 24 hours, revealing adrenal function and sleep disturbances.

  • Melatonin Levels: Evaluates sleep-wake cycle regulation and whether disrupted sleep is hormone-related.

  • Sex Hormones (Oestrogen, Progesterone, Testosterone): Identifies imbalances causing fatigue, mood swings, and menstrual irregularities.

  • Hormone Metabolism & Detoxification: Assesses liver processing of hormones, oestrogen dominance risks, and conditions like PCOS, fibroids, endometriosis, and hirsutism.

  • Environmental Toxins: Detects hormone-disrupting chemicals (plastics, phthalates) affecting metabolism and detoxification.

Why Do This Test?

  • Identifies the root cause of hormonal symptoms (fatigue, mood swings, weight gain, insomnia, brain fog).

  • Assesses adrenal function and stress resilience for managing burnout.

  • Guides personalised hormone therapy and detox strategies.

Comprehensive Gut Microbiome Analysis

Why do a microbiome test?
Your gut microbiome influences everything — from mood and immunity to inflammation and detoxification.

Think: bloating, loose stools, constipation, inflammatory bowel disease, cancer risk markers, allergic reactions, skin issues like eczema and acne, period pain, heart disease risk, autoimmune flares, low immunity, frequent colds, runny nose, watery eyes, low mood, anxiety, fatigue, brain fog, and blood sugar imbalances.

It’s not just about digestion — it’s your whole system.

The Microbiome Test is an advanced stool analysis that assesses the composition and function of your gut bacteria, identifying imbalances that may contribute to digestive issues, inflammation, and chronic health conditions. Unlike standard tests, it provides a detailed map of your gut microbiome, helping pinpoint the root cause of symptoms and guiding targeted interventions for gut health, immune function, and overall well-being.

Who Should Consider This Test?

This test is beneficial for individuals experiencing:

  • Bloating, gas, acid reflux, low appetite, constipation or diarrhoea

  • IBS, SIBO, leaky gut, or food sensitivities

  • Skin conditions like acne, eczema, or rosacea

  • Brain fog, fatigue, depression, or anxiety

  • Autoimmune disorders and chronic inflammation

  • Weight management issues or metabolic imbalances

What the Microbiome Test Measures

  • Gut Bacteria Balance: Identifies beneficial vs. harmful microbes affecting digestion, immunity, and metabolism.

  • Pathogens & Dysbiosis: Detects bacterial, viral, and fungal overgrowths linked to IBS, SIBO, and infections.

  • Inflammation & Leaky Gut Markers: Measures gut permeability, immune response, and inflammation levels.

  • Digestive Function: Assesses enzyme activity, bile acids, and short-chain fatty acid production for nutrient absorption.

  • Metabolic Health & Toxin Clearance: Identifies microbiome-related factors affecting detoxification, hormone metabolism, and weight regulation.

Why Do This Test?

  • Pinpoints the root cause of digestive issues and food intolerances.

  • Optimises gut health to improve energy, mood, immunity, and metabolism.

  • Detailed individualised dietary, probiotic, and lifestyle interventions for long-term gut balance.
