Functional tests are tests which indicate how well the body's systems are functioning. They help a practitioner identify deficiencies, excesses and imbalances which may underlie health difficulties, prevent recovery or increase disease risk. The test may involve taking a saliva, blood, urine or stool sample for laboratory analysis. Tests can either be taken at home or in the nutrition clinic, but some samples will require blood to be drawn by a nurse or phlebotomist. All analysis are performed at reputable laboratories in the UK.
Functional tests may be used to asses:
I will only recommend private functional tests when considered absolutely necessary as they can be costly, but of great value to inform clinical decisions. Clients will receive a full report of the test results, and interpretation and advice will be provided at the nutritional clinic.
Companies I use for functional tests include:
Lorisian Food Intolerance Test
York Food Intolerance Test
