Functional Testing
NUTRITIONAL THERAPY WITH A FUNCTIONAL MEDICAL APPROACH
What is functional testing?
Functional testing examines how well your body’s systems are working, rather than just diagnosing diseases. It looks at:
​
-
Biochemical imbalances: Nutrient deficiencies, hormone levels, or metabolic issues.
-
Digestive health: Gut microbiome, food sensitivities, or intestinal permeability (leaky gut).
-
Detoxification pathways: How well your liver and kidneys are processing toxins.
-
Immune function: Markers of inflammation or immune system activity.
-
Stress and adrenal health: Cortisol levels and how your body responds to stress.
​
These tests provide a detailed picture of your overall health and help identify areas for improvement, even if you don’t have a specific diagnosis.
How does functional testing differ from GP testing?
Functional testing is a comprehensive approach to health assessment that goes beyond standard medical tests to uncover the root causes of symptoms and imbalances. It focuses on optimising health and preventing disease by evaluating how different systems in the body are functioning. Here’s a breakdown of what it involves and how it differs from GP testing:
Why choose functional testing ?
-
Personalised Insights: Functional testing provides a deeper understanding of your unique health profile, helping to tailor interventions specifically to you.
-
Preventive Care: It identifies imbalances early, allowing you to address issues before they develop into chronic conditions.
-
Holistic Approach: It considers the interconnectedness of body systems, offering a more comprehensive view of your health.
-
Optimisation: Even if you feel “fine,” functional testing can help you achieve optimal health and performance.
When is functional testing useful?
-
You have unexplained symptoms (e.g., fatigue, bloating, brain fog).
-
You want to optimise your health and prevent future issues.
-
You have a chronic condition and want to explore underlying causes.
-
You’re looking for a personalised approach to diet, lifestyle, or supplementation.
