Peanut (Arachis hypogaea) Allergy (IgE)
A common legume and one of the most serious food-allergy triggers.
Consider this test if:
- Hives, swelling, vomiting, or breathing trouble after eating peanut or peanut-containing foods
- A prior reaction and you want to confirm whether peanut is the trigger
- Family history of food allergy and you want to assess sensitization before introducing or avoiding peanut
- Eczema or existing food allergies and ongoing reactions of unclear cause
- HSA/FSA eligible
- Results delivered to your dashboard · Reviewed by a real clinician
- Drawn at a CLIA/CAP-accredited lab near you ·
Pre-test considerations
No fasting required and no special timing. Antihistamines and other medications do not affect blood IgE results, so there is no need to stop them beforehand.

What this test is for
Peanut is a legume found in many foods and processed products, and it is among the most common causes of severe, sometimes life-threatening food allergy. This test measures IgE antibodies to peanut, the antibody class that drives immediate allergic reactions. A positive result means sensitization, not a confirmed allergy: a true allergy requires symptoms that track with exposure, so the result is read against your reaction history. The separate peanut IgG and IgG4 tests reflect exposure and immune memory, not allergy; if your question is whether you are truly allergic, this IgE test is the right marker.

- Specimen
- Serum
- Measures
- Concentration
Peanut IgE measures allergen-specific antibodies your immune system built against peanut proteins, the same antibodies that trigger histamine release on exposure. A positive result confirms sensitization and helps explain hives, swelling, GI upset, or more severe reactions after peanut exposure, distinguishing true allergy from intolerance or a one-off reaction. This is useful for confirming a suspected allergy, tracking whether sensitization is fading over time, or clarifying risk before reintroducing peanut into a diet.

Frequently asked questions
View all FAQsHow does pricing work?
Every test shows the member price next to the standard non-member price, so you can see what membership saves you. The member price is our cost — covering the lab and what it takes to run the service — never a profit on the test itself; Mito makes its money on the $9 membership, not on marking up your tests. Membership is $9/mo, and you still pay the lab’s order fee. Prices are itemized before you pay, with no hidden fees.
Where do I get tested?
Choose a partner lab (Quest, Labcorp, or BioReference) at checkout. If your cart spans multiple tests, we consolidate the whole order onto a single lab so you only make one visit.
Is this eligible for HSA/FSA?
Yes. This test is HSA/FSA eligible, and you can pay with your HSA/FSA card at checkout.
When will I get my results?
Your results post to your dashboard once your lab completes them, then a clinician reviews them and your full analysis and personalized action plan (with clear next steps) follow. Turnaround varies by test: specialty assays and at-home kits take longer, and each test shows its expected turnaround before you buy.
Do I need a doctor’s order?
No. Mito provides the lab order for you, so you can book and get tested without a separate doctor visit.
