As a profession, Nutritional Therapists have access to a broad range of laboratories and their diagnostic tests (including DNA/genetic profiling), that cover all of the core functional systems of the body.
Tests are only recommended when it is considered essential for the provision of effective and safe therapeutic interventions and always in negotiation with each client. Tests are considered on a case by case basis. I only use the most reputable laboratories with a proven track record that I trust.
Typical Tests might include:
Multi-tissue antibody testing
Food allergy & intolerance testing
Hormone & adrenal profiles
Digestive system stool analysis
