Common Questions About Testing
Frequently asked questions to help you understand processes, timelines, and next steps.
What is the difference between allergy and intolerance?
Allergies involve the immune system and can cause immediate reactions, while intolerances typically affect digestion and cause delayed symptoms. Testing helps clarify which you may have.
How long until I get results?
Turnaround depends on the specific test; most results arrive within 5 to 14 days. Exact timing is provided when you book.
Can children be tested?
Yes. Many tests are suitable for children; we assess suitability and guide parents through preparation and interpretation.
Do I need a referral from a doctor?
Referrals are not usually required for basic testing. For specialist allergy assessment or if anaphylaxis is suspected, we recommend medical referral.
Will testing tell me exactly what to avoid?
Tests identify markers and likely triggers but should be combined with symptom history. We provide practical elimination and reintroduction plans rather than blanket restrictions.
