Peanut Allergy Testing
View All TestsWhat Is Peanut Allergy?
Peanut allergy is one of the most common and potentially serious food allergies, particularly in children. It involves an IgE-mediated immune response to proteins found in peanuts (a legume, not a true nut). Reactions can range from mild oral symptoms to severe anaphylaxis.
Component-resolved diagnostics (CRD) can identify which specific peanut proteins you may be sensitised to — such as Ara h 2, which is associated with a higher risk of systemic reactions, or Ara h 8, which is a birch pollen cross-reactive protein typically associated with milder oral symptoms.
Our blood tests provide detailed component-level results that you can share with your GP or allergist for interpretation and risk assessment. If you have a known peanut allergy with a history of severe reactions, always follow your existing emergency action plan.

Frequently Asked Questions
What is component-resolved testing for peanut?
Instead of testing for peanut as a whole, component testing measures IgE to individual peanut proteins (Ara h 1, 2, 3, 6, 8, 9). This can help your specialist understand your risk profile, as different components are associated with different types and severities of reaction.
Does a positive test mean I will have an anaphylactic reaction?
Not necessarily. Sensitisation (a positive IgE result) does not always mean clinical allergy. Your specialist will interpret results in the context of your clinical history to assess your individual risk.
Do I need a GP referral for allergy testing?
No. You can book directly with our clinic without a GP referral. Simply choose your test and select a convenient appointment time. If you're unsure which test is right for your symptoms, our team can help guide your selection.
Do I need to stop taking antihistamines before a blood test?
No. Unlike skin prick testing, IgE blood tests are not affected by antihistamines or other allergy medications. You can continue taking your regular medications before your appointment.
What should I do with my results?
As a diagnostic-only clinic, we provide results directly to you. We strongly recommend sharing them with your GP or allergist for interpretation, risk assessment, and guidance on dietary management.
