Pistachio Allergy (IgE)
A tree nut and a common trigger of food-allergy reactions.
Consider this test if:
- You had hives, swelling, mouth itching, or vomiting after eating pistachio or mixed nuts
- You react to cashew and want to check the closely related pistachio
- You are confirming which specific tree nuts to avoid before allergy testing or a food challenge
- A prior reaction to nuts was severe and you want to clarify the trigger
- 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 timing does not matter. Antihistamines and other medications do not affect blood IgE results, so you do not need to stop them before testing.

What this test is for
Pistachio is a tree nut found in snacks, baked goods, desserts, and many prepared dishes, and it is among the nuts that cause food-allergy reactions ranging from mouth itching and hives to swelling and anaphylaxis. This test measures IgE antibodies to pistachio, 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. Tree nut allergies often cluster, so reactions to pistachio frequently prompt evaluation of related nuts such as cashew.
Biomarkers tested
Includes 2 biomarkers
This test measures IgE antibodies your immune system builds specifically against pistachio 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, in severe cases, breathing trouble that follow eating pistachios or foods cross-contaminated with tree nuts. It is useful both for confirming a suspected pistachio allergy after a reaction and for screening before introducing pistachios or cashews (a close botanical relative) into your diet, since cross-reactivity between the two is common.

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. It is never a profit on the test itself. Mito makes its money on the $9 membership, not on marking up your tests. Membership is $9 per month, and any applicable lab order or draw fee is itemized before you pay.
Where do I get tested?
Choose an available partner lab at checkout. If your cart contains multiple blood tests, Mito helps consolidate the eligible tests at one lab when possible. At-home kits and scans follow the collection or appointment process shown on their product page.
Is this eligible for HSA/FSA?
Yes. Eligible tests can be paid for with an HSA or FSA card at checkout.
When will I get my results?
Your results appear in your Mito dashboard after the laboratory completes processing. A clinician then reviews them before your analysis and personalized action plan are finalized. Timing varies by test, and specialty assays and at-home kits may take longer.
Do I need a physician's order?
No. Mito provides the laboratory order when one is required, so you do not need to arrange a separate physician visit before purchasing.
