Doctor's Assessment Included
Every result includes a professional assessment from a BIG-registered doctor. For treatment decisions, discuss your results with your GP.
Nut Panel 2 (fx22)
The Nut Panel 2 (fx22) complements fx1 for comprehensive tree nut allergy assessment, covering the most clinically relevant additional nut allergens.
What It Measures
This panel measures specific IgE antibodies against walnut, cashew, pecan, pistachio, and macadamia. A positive result indicates sensitisation to at least one nut in this mix.
Why It Matters
Cashew and walnut allergies are among the most common causes of severe nut-related anaphylaxis. This panel covers species not included in fx1.
When to Test
Consider this panel alongside fx1 for comprehensive nut allergy assessment, or if you have experienced reactions after eating walnuts, cashews, or pistachios.
Lifestyle Tips
If sensitisation is confirmed, your allergist will advise which nuts to avoid. Cross-reactivity between cashew and pistachio is very high, and between walnut and pecan. Always carry emergency medication.
