Safe & Gentle Testing Protocols
Douglas offers a high level of expertise using dietary and environmental testing protocols that may help uncover intolerances and sensitivities through advanced computerised assessment techniques. These methods are:
- Drug-free – no pharmaceutical medication is involved*
- Needle-free – no blood tests or injections required
- Quick and non-invasive – suitable for all ages, even babies from 6+ months
Each assessment is complemented by supportive, personalised recommendations designed to help you manage symptoms naturally and encourage a healthier, more balanced response to your condition.

Choosing the Right Clinic
When it comes to testing for food sensitivities, it is important to select a clinic that:
- Specialises in food and environmental testing as a primary focus, rather than offering it occasionally.
- Provides a complete recovery program, not just a test result, to give patients the best chance at long-term improvement.
- Has extensive experience treating thousands of clients with a wide variety of conditions—sometimes multiple issues at once (for example: Hives, Candida, Diabetes, and Hayfever).
This depth of knowledge demonstrates true practitioner competence and ensures that patients receive informed, safe, and effective support.
At our clinics, we have built our reputation on exactly these foundations—experience, attention to detail, and the use of modern computerised testing facilities.
