Purpose and selection
This imported listing concerns food-specific IgG. AAAAI recommends against using food IgG panels to diagnose food allergy or intolerance. Do not use this listing to choose an exclusion diet; discuss symptoms with an allergy clinician first.
An allergy clinician should assess the symptoms before any testing or dietary restriction. Food-specific IgG is not an established way to diagnose food allergy or food intolerance.
What this request includes
- Confirm the requested test
- Confirm sample and preparation
- Confirm collection and report pathway
- Ask about current availability
Preparation before collection
Follow the performing laboratory’s test-specific instructions. Do not stop or change medicines or supplements without advice from your healthcare provider.
Important limitations
AAAAI advises against using food IgG panels for these diagnoses. A positive IgG result may reflect food exposure rather than a harmful reaction. Do not use it alone to remove foods from your diet.
Understanding the result
Use the performing laboratory’s complete report, method, units and reference range. The requesting clinician should interpret it with your symptoms, history, medicines and other relevant findings.
After testing and follow-up
Agree who will explain the report and whether follow-up is needed. Do not start treatment or change medicines from a catalogue entry or one result. Seek medical care for significant or worsening symptoms rather than waiting for a routine enquiry.
