Symptoms do not always reflect what is happening beneath the surface. In many chronic conditions, measurable improvements in physiology may occur long before noticeable changes in symptoms. Laboratory testing can therefore provide objective information about your health, helping to identify underlying imbalances, establish a baseline, monitor your progress, and refine your treatment programme where necessary.
Laboratory testing is always optional and is not necessary for everyone. Where appropriate, I will recommend the investigations that are most likely to answer a specific clinical question and discuss the available options and costs before any tests are arranged.
Metabolic & Mitochondrial Testing
My particular area of expertise is redox biology and mitochondrial metabolism. I therefore offer several specialist investigations that assess cellular metabolism and mitochondrial function, including:
- Metabolic Insights — Approx: £ 302
A non-invasive saliva test that measures the downstream products of your diet and metabolic rate. It is best if you want a broad overview view of how lifestyle adjustments are affecting your metabolic byproducts over time. It is highly sensitive to rapid dietary adaptations but lacks deep cellular resolution.
- Mitochondrial Functional Testing — Approx: £ 125 - 485
Directly assesses the mitochondrial function of live white blood cells using the Seahorse XF Analyzer, which is considered the scientific gold standard for real-time cellular respiration profiling. This test is best used when there is suspected mitochondrial dysfunction because it directly evaluates your cells' ability to operate under stress, but it requires organising a blood draw.
- NAD Testing — Approx: £ 199
A highly sensitive chemical assay kit that breaks down your exact levels of reduced and oxidised Nicotinamide Adenine Dinucleotide (NAD) and glutathione, two markers which can be used to reveal age-related metabolic decline, or to determine tailor exactly how much interventions are modifying your NAD profile. This test also requires a blood draw.
General Functional Laboratory Testing
I work with several specialist laboratories, providing access to a wide range of investigations covering general health, nutritional status, gut health, hormone function, microbiome analysis, and many other areas. Some of the most popular include:
- Microbiome Profiling — Approx: £ 270 - 502
The GI360 test provides comprehensive, advanced stool-based analysis that evaluates gut microbiome balance, detects gastrointestinal pathogens, and assesses overall digestive and immune health.
- Hormone Profiling — Approx: £ 213 - 458
The Dried Urine Test for Comprehensive Hormones (DUTCH) evaluates a person's sex and stress hormones and their breakdown products using dried urine samples collected over a 24-hour period.
- Autoimmune Profiling — Approx: £ 177 - 354
Assay specific immune markers to evaluate cellular integrity, immune system types, and potential pathogen or autoimmune triggers. Requires a blood draw.
- Wellness Profiling — Approx: £ 137 - 317
Evaluates white blood cell count, differentials, red blood cell panels, Omega 6:3 ratio, HbA1c, oxygen and nutrient transport, and more, to provides a thorough assessment of overall health and wellness and suggestions for micronutrient needs . Also available with additions for gender specific wellness markers. Requires a blood draw.
- Liver and Kidney Function — Approx: £ 100
A useful monitor for those on long term, high dose herbs, especially if also taking medication. It also tests for gastrointestinal inflammation, protein status, and specific vitamin and mineral levels. Available as a fingerprick test.
Many investigations require only saliva, urine, or stool samples that can be collected at home. Others require a blood sample, which can be arranged through a local phlebotomist. I can advise which tests are most appropriate for your circumstances, explain how to prepare, and help interpret the results in the context of your treatment.
Supplement Quality Verification
I can also arrange independent chromatographic and spectroscopic analysis of supplements and nutritional formulas—including those I prescribe— through independent analytical laboratories such as Campden BRI, a UK laboratory specialising in analytical testing for the food, pharmaceutical and healthcare sectors. This can verify their contents and screen for contaminants such as heavy metals, adulterants, or undeclared pharmaceutical substances, providing additional reassurance about the quality of the products you are taking.
