Functional Health Testing

Understanding what's really going on in your body

Sometimes you can feel that something isn't quite right, but routine GP tests come back "normal." If you're still experiencing symptoms, struggling with energy, hormones, digestion, or weight, the answer may lie deeper than standard blood work can show.

Functional testing offers a more detailed and personalised picture of your health. Rather than looking for disease, these tests assess how well your body is actually functioning, so we can identify imbalances, deficiencies, and patterns that may be contributing to how you feel.

As a Nutritional Therapist, I work with a range of specialist laboratory tests to support a truly root-cause approach to your health.

Tests Available

Comprehensive Stool Analysis

This test, also known as Gut Microbiome Test, assesses how well your digestive system is functioning and can reveal a great deal about the underlying drivers of gut-related symptoms.

It looks at:

  • Digestive function, including enzyme and bile acid levels

  • Markers of gut inflammation

  • The presence of parasites, yeast overgrowth, pathogenic bacteria, and viruses

You may benefit from this test if you're experiencing:

  • Bloating, wind, or abdominal discomfort

  • Constipation, diarrhoea, or irregular bowel habits

  • Nausea or a feeling of heaviness after eating

  • Unexplained fatigue that could be gut-related

  • Skin issues such as eczema, acne, or rosacea

  • Food intolerances or sensitivities

  • Anxiety, low mood, or brain fog (gut health and mental wellbeing are closely linked)

Women’s Hormone Testing

Hormone imbalances can affect every aspect of how you feel, from your energy and mood to your weight, sleep and menstrual cycle. In my clinic I offer three specialist home tests that give a detailed picture of your hormonal health:

  • DUTCH Complete (Precision Analytical): evaluates 35 sex and adrenal hormones and their metabolites, along with your daily free cortisol and cortisone patterns, melatonin, 8-OHdG and nine organic acids. These organic acids give further insight into nutrient needs and neurotransmitter balance. For a closer look at your stress response, the DUTCH Plus (Complete + CAR) adds extra cortisol analysis, including your Cortisol Awakening Response.

  • HuMap (Doctors Data): a urine-based profile of your steroid hormones and how your body is metabolising them, with cortisol measured at four points across the day and a close look at oestrogen metabolism.

  • Women’s Health+ (Genova Diagnostics): combines saliva measurements of your sex hormones and cortisol rhythm with urine markers of oestrogen metabolism and organic acids, with an optional genetic analysis.

You may benefit from hormone testing if you’re experiencing:

  • Irregular, heavy, or painful periods

  • PMS or mood changes linked to your cycle

  • Symptoms of perimenopause such as hot flushes, night sweats, or sleep disruption

  • Persistent fatigue, particularly if it varies throughout the month

  • Anxiety, low mood, or irritability

  • Difficulty losing weight despite doing “all the right things”

  • Low libido

  • Signs of high cortisol such as waking at 3am, feeling wired but tired, or struggling to manage stress

Lifecode Gx Nutrigenomics Testing

These pioneering tests looks at your unique genetic profile to understand how your genes interact with nutrition, lifestyle, and environment. Rather than a one-size-fits-all approach, nutrigenomics allows us to tailor your nutritional plan to your individual genetic potential.

Areas explored include how your body processes nutrients, responds to certain foods, manages inflammation, and how factors such as exercise and stress interact with your genetic make-up. Depending on what you're looking to understand, we can focus on specific reports, including methylation (how your body processes folate and manages your methylation cycle), detoxification (how efficiently your body clears toxins and processes them), hormones (your genetic predispositions around hormone metabolism), and nervous system (how your genes influence mood, stress response, and resilience).

You may benefit from this test if you're:

  • Feeling as though generic dietary advice simply doesn't work for you

  • Interested in a truly personalised, long-term approach to your health

  • Dealing with chronic symptoms that haven't responded to standard interventions

  • Looking to understand your genetic predispositions around weight, energy, or hormonal health

  • Keen to optimise your health and wellbeing for the long term

Functional DX Ultra (Advanced Blood Markers)

This comprehensive blood test goes far beyond what's typically offered by your GP and covers a wide range of markers to assess how your body is functioning across multiple systems.

It includes:

  • Blood glucose and insulin regulation

  • Thyroid function

  • Liver and gallbladder health

  • Kidney function

  • Iron levels and anaemia markers

  • Inflammatory markers

You may benefit from this test if you're experiencing:

  • Unexplained weight gain or difficulty losing weight

  • Fatigue, brain fog, or difficulty concentrating

  • Feeling cold all the time, dry skin, hair thinning, or constipation (potential thyroid signs)

  • Bloating or digestive discomfort after meals

  • High stress levels and symptoms of inflammation

  • A general sense that something isn't right, but routine tests haven't given you answers

How It Works

Getting started with functional testing is straightforward. Here's what to expect:

1. Get in touch Contact me to have a conversation about which tests may be most relevant for you, based on your symptoms and health goals. I'll walk you through the options available and their associated costs.

2. I place the order Once we've agreed on the right test, I'll place the order directly with the testing laboratory. Your test kit will be shipped straight to your home address, ready for you to use at your convenience.

3. You complete the test Full instructions are provided by the testing company. You simply follow the guidance, complete the sample collection, and return it to the laboratory using the prepaid packaging and instructions included.

4. Results review and your roadmap Once your results are ready, a comprehensive report is shared with me. I'll carry out a full interpretation and then arrange a call with you to go through the findings in detail. You'll leave that call with a clear, personalised roadmap of next steps.
