Functional testing is an important part of the jigsaw when working to achieve optimum health

Functional tests, either through the GP or from leading private providers, can provide deeper insight into how your body is functioning, and why you are experiencing the symptoms you are. The results will help inform my strategy for optimising your health status, and can help us address the root causes of your food reactivity and reach your goals faster.

I will always explain why I think a test will be useful, along with the cost implication and what it would entail. The decision on whether or not to go ahead is always yours.

Tests typically involve providing one or more samples of breath, saliva, blood, urine or stool. Many tests can be done simply, at home. Blood tests may involve travelling to a clinic where blood can be taken, though mobile services that visit your home are also available.

Things I may advise testing include:

Digestive function & microbiome analysis

Infections (e.g. viruses or parasites)

Food or autoimmune reactivity

Intestinal permeability

Histamine and diamine oxidase

Nutrient status

Hormones (stress, thyroid or reproductive hormones)

Metabolic markers


Immune markers
