Pecan Nut (Carya illinoinensis) Allergy (IgE)
A tree nut and common food-allergy trigger, sometimes behind serious reactions.
Consider this test if:
- Hives, swelling, mouth itching, or trouble breathing after eating pecans or pecan-containing foods
- A known allergy to walnut or other tree nuts and you want to check pecan cross-reactivity
- Building an allergy profile before introducing or reintroducing tree nuts
- Past reactions to mixed nuts where the specific trigger was never identified
- 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 interfere with a blood IgE test, so you do not need to stop them beforehand.

What this test is for
Pecan is a tree nut found in baked goods, desserts, and many packaged foods, and it is among the tree nuts that can cause significant allergic reactions. This test measures IgE antibodies to pecan, 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. Pecan shares proteins with other tree nuts such as walnut, so people sensitized to one are often sensitized to the other.
Biomarkers tested
Includes 2 biomarkers
- Specimen
- Serum
- Measures
- Concentration
This test measures IgE antibodies your immune system builds specifically against pecan or hickory nut proteins, the flag it raises when it mistakes a harmless food for a threat. A positive result explains reactions like hives, swelling, itching, stomach upset, or breathing trouble after eating pecans, and helps confirm a suspected nut allergy rather than a one-off intolerance. If you've never reacted but eat pecans regularly with no issue, a negative result simply rules out sensitization worth worrying about.

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.
