A Brazil nut allergy test checks your blood for antibodies that may indicate an allergy to Brazil nuts. It is usually ordered when you have had allergic symptoms after eating Brazil nuts or when your doctor needs to confirm a suspected allergy.

What it measures

  • Brazil nut-specific IgE — Antibodies made by your immune system that target Brazil nut proteins.
  • Total IgE — A general measure of allergic antibody levels in your blood, sometimes used for context.
  • Component allergens (e.g., Ber e 1) — Specific proteins in Brazil nuts that can help show how likely a reaction is.
  • Cross-reactive markers — Proteins shared with other nuts or pollens that may cause a positive test without a true allergy.

Who it is for

This test is typically ordered by an allergist, immunologist, or primary care doctor for people who have had symptoms after eating Brazil nuts or who need to check for a possible allergy.

Preparation
