Frequently Asked Questions (FAQ's)
1. What is the difference between food intolerance and food allergy?
A food allergy involves an immediate immune response triggered by IgE antibodies and can cause serious or life-threatening symptoms. A food intolerance (or sensitivity) usually involves a delayed reaction, often linked to IgG antibodies, and may cause symptoms such as bloating, fatigue, skin irritation, or digestive discomfort.
​
2. What is bioresonance testing and how does it work?
Bioresonance testing uses a device to detect subtle energetic imbalances in the body that may indicate stress or reactions to certain foods. The test is carried out using mild frequencies introduced via acupuncture points on the hands and feet. It is completely non-invasive and aims to identify foods or systemic imbalances contributing to your symptoms.
​
3. What does a YorkTest IgG food intolerance test cover?
The YorkTest IgG food intolerance test analyses your immune response to up to 200 food and drink ingredients using a small blood sample collected via finger-prick. Results are usually returned within 7 working days and include a detailed food fingerprint report showing which foods your immune system may be reacting to.
​
4. What does a YorkTest IgE allergy test cover?
The YorkTest IgE allergy test measures your immune system’s IgE reactions to key food and drink allergens. It is ideal for identifying potential triggers for symptoms such as rashes, breathing issues, or swelling. If you have already been diagnosed with an allergy and have avoided the allergen for some time, it may not show a positive reaction.​
5. Who should not take these tests?
-
IgG intolerance testing: not suitable during pregnancy, breastfeeding, or for children under 4.
-
IgE allergy testing: not suitable during pregnancy, breastfeeding, or for children under 4.
-
Bioresonance testing: not suitable during pregnancy, for those with pacemakers, or for children under 3.
​​
6. How long do results take and what happens next?
-
YorkTest IgG and IgE tests: Results are usually ready within 7 working days.
-
Bioresonance testing: Results are available immediately at the end of your appointment.
​
7. What do the results mean and what should I do next?
Your results will highlight foods or ingredients your body may be reacting to.
Next steps may include:
-
Working with your practitioner to interpret the results in context.
-
Following an elimination plan to remove or reduce reactive foods.
-
Gradual reintroduction under guidance.
-
Ongoing nutritional support to promote gut health and long-term balance.
​
8. What should I do if I receive a positive IgE (allergy) result?
A positive IgE result indicates your immune system is producing antibodies to specific allergens, consistent with a true food allergy. You should discuss your results with your GP or an allergy specialist for confirmation and advice.
​
While waiting for your appointment, avoid the foods identified and monitor your symptoms. If you experience severe allergic reactions such as swelling, difficulty breathing, or anaphylaxis, seek immediate medical advice and carry any prescribed emergency medication.
