Bertholletia excelsa Ab.IgE

This test detects IgE antibodies against Brazil nut proteins, indicating a potential tree nut allergy. Brazil nuts are common allergens that can trigger reactions ranging from mild oral itching to severe anaphylaxis in sensitive individuals. Tree nut allergies often persist throughout life and may involve cross-reactivity with other nuts or seeds. A positive result confirms Brazil nut allergy and warrants careful label reading and emergency preparedness with an epinephrine auto-injector if recommended by your doctor.
