The Nut Allergy Test Panel is a blood test that checks for allergic sensitization to common tree nuts and peanut. It is often ordered when a person has had allergic symptoms after eating nuts or when a clinician needs to assess the likelihood of a nut allergy.

What it measures

  • Peanut-specific IgE — Antibodies that may indicate sensitization to peanut proteins.
  • Tree nut mix-specific IgE — Antibodies that may indicate sensitization to a mix of tree nuts such as almond, cashew, and walnut.
  • Individual tree nut-specific IgE — Separate tests for nuts like hazelnut, pecan, or pistachio, if ordered.
  • Total IgE — A general antibody level that can help interpret specific results.

Who it is for

A clinician such as an allergist, primary care provider, or pediatrician typically orders this panel after a suspected reaction to nuts or when evaluating allergy risk.

Preparation

No fasting is required. Tell your clinician about any medications you take, especially antihistamines, as they may affect some allergy tests.

Results and what they mean

Results are reported as numeric levels for each nut-specific IgE. Higher levels suggest a greater chance of allergy, but results must be interpreted by a clinician along with your history and other tests. This is general information, not medical advice.

Frequently asked questions

Does a positive result mean I am definitely allergic?

No. A positive result shows sensitization, which may or may not cause symptoms. A clinician uses your history and other findings to decide.

Can I eat nuts before the test?

Yes, no fasting is needed. However, if you have had a severe reaction, avoid the nut until you speak with your clinician.

How long does it take to get results?

Typical turnaround is 1 to 3 business days after the blood sample is received by the lab.

Is this test painful?

It is a standard blood draw, which usually causes brief discomfort. No needles stay in place.
