About Functional Medicine Testing

At Steve Grant Health, we offer a selection of Functional Medicine tests available across the UK, designed to uncover the underlying causes of your symptoms and help you make informed, data-driven decisions about your health.

Our testing service combines scientific accuracy and should you wish to add it, clinical interpretation, guidance and protocols. This gives you meaningful insights into your metabolic, hormonal, cardiovascular, digestive, and nutritional health and practical solutions to address any noted imbalances in context with your given situation and goals.

Whether you want to take a proactive approach to prevention or resolve long-standing health issues, our tests help you move from uncertainty to clarity.

About Functional Medicine Testing
Why Chose Functional Medicine Testing

Why Choose Functional Medicine Testing

Functional Medicine testing and interpretation takes a root-cause approach, helping to identify early dysfunctions before they progress into chronic illness or dysfunction.

Our advanced laboratory assessments can help identify:

Metabolic imbalances affecting energy and weight regulation.
Hormonal changes influencing mood, fertility, or stress response.
Digestive issues such as bacterial overgrowth, dysbiosis, or food sensitivities & allergies.
Cardiovascular and inflammatory imbalances to long-term heart and metabolic risk.
Nutrient deficiencies affecting immunity, cognition, energy and vitality.

Each test helps to offer a picture of your health, allowing for targeted, personalised interventions rather than guesswork.
