A peanut allergy test checks your blood for antibodies that may indicate an allergy to peanut proteins. It is usually ordered when someone has had a reaction after eating peanuts or peanut-containing foods, or to help confirm or rule out a suspected peanut allergy.

What it measures

  • Peanut-specific IgE — An antibody made by the immune system that can be linked to peanut allergy.
  • Total IgE — A general measure of allergic antibody levels in the blood; it does not diagnose peanut allergy by itself.
  • Peanut component proteins — Specific peanut proteins such as Ara h 1, 2, 3, 8, and 9 that may help show which peanut proteins trigger a reaction.

Who it is for

A doctor, allergist, or other clinician typically orders this test. It may also be ordered for a child or adult with a history of hives, swelling, breathing trouble, or digestive symptoms after peanut exposure.

Preparation

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

Results and what they mean

Results are reported as a number for peanut-specific IgE and, if done, for individual peanut proteins. Higher numbers may suggest allergy, but results must be interpreted by a clinician along with your history and symptoms. This is general information, not medical advice.

Requesting the Peanut Allergy Test in Oregon

Order online, choose a certified collection site in Oregon, and review results through a secure portal. No referral is required, and orders are processed confidentially. Access across Pacific is uneven, so confirming a site ahead of time is worthwhile.

Frequently asked questions

Does this test hurt?

It uses a standard blood draw from a vein, which feels like a brief pinch.

How long do results take?

Most results are ready in 1 to 3 business days.

Can this test alone diagnose a peanut allergy?

No. A clinician interprets the result with your symptoms and may order other tests.

Do I need to avoid peanuts before the test?

Ask your clinician. In most cases, you do not need to change your diet before a blood test.
