Functional testing

Functional testing may be recommended to assess nutritional imbalances and inform personalised diet and lifestyle recommendations to support wellbeing

Functional tests provide detailed data relating to how a system (s) in your body is functioning, they move beyond a reference range and can help understand the ways in which a particular system is working. Testing can guide decisions, and monitor interventions. This can be very beneficial to provide targeted support and your health outcomes.

There are 1000s of functional tests, varying in price, sampling approach (blood draw, saliva, urine and stool), many of which can be completed at home. More information and indicative pricing can be found here.

Functional tests can provide both reassurance and direction in many clients. Advice and guidance as to what is appropriate for you, will be discussed in our consultation, and a sample test can be provided. Whilst testing may be clinically relevant, it is your choice to test.

If some tests are available on NHS, I will support you in asking for these (for example Cholesterol, Blood glucose levels, Full Blood count) we will ensure that the NHS pathway is used initially, we may then decide after this to delve deeper based on these results, through a functional test.

Many tests are not available on the NHS, but can be key to outcomes, such as hormone panels, auto immune panels. I will support you to prepare for the test and engage with laboratory test companies where needed.

I partner with top laboratories in the UK, Europe, and the USA, including Cyrex, Genova Diagnostics, Precision Analytical, Invivo Diagnostics, Functional Dx, Colabs, Vivo Health, Regenerus Laboratories, Viva Health Laboratories, and Lifecode Gx.

Due to the wide array of tests and price range, these are not included in my pricing, indicative pricing for a selection of tests is included here
