The Food Allergy Panel tests for IgE antibodies to 12 of the most common food allergens: peanut, walnut, cow's milk, egg white, wheat, soybean, shrimp, scallop, clam, codfish, corn, and sesame. IgE-mediated food allergies can cause reactions ranging from hives and swelling to anaphylaxis. This panel helps identify specific food triggers so you can avoid them. For broader tree-nut coverage (almond, cashew, pecan, pistachio and more), see the Tree Nut & Peanut Allergy Panel. Note: this tests for true allergies (IgE-mediated), not food sensitivities or intolerances, which involve different immune mechanisms.
IgE blood-allergy screen across 88+ common food allergens (dairy, eggs, peanuts, tree nuts, soy, wheat, shellfish, fish). The standard blood-based alternative to skin-prick testing.
Anyone with suspected food allergy symptoms (hives, swelling, GI distress, anaphylaxis), eczema-prone children, before introducing high-allergen foods to infants with family history, or unable to undergo skin testing (severe eczema, antihistamine use).

12 biomarkers tested
Your Food Allergy Panel results will include values for each of the 12 biomarkers tested, along with reference ranges. Results are reviewed by a licensed physician before being released to your secure portal.
If any values fall outside the normal range, your report will include guidance on what that may mean and recommended next steps. You'll receive an email notification when your results are ready, typically within 5–7 business days.
Typical reference range layout
Lab reports show where your value sits relative to established reference intervals—your physician interprets this in context for you. Already have results? Analyze them with your AI assistant against our physician-reviewed ranges.
No fasting required. Do not take antihistamines for 7 days before if possible (consult your doctor first).
A Food Allergy Panel costs $150.99 at TestWell — $156.99 all-in when ordered alone, because the $6 lab processing fee is charged once per order, with no draw fee or physician fee added. Ordered directly from the labs' own consumer sites, the closest equivalent lists at $209.00 at Labcorp OnDemand (list prices checked Sep 12, 2026; see the notes on how the products differ). Hospital outpatient labs typically bill around $400.00 self-pay for the same test, and often more. With insurance, what you pay depends on your deductible and your plan's negotiated rate; TestWell's price is fixed before the draw and is HSA/FSA-eligible.

True food allergies are IgE-mediated immune reactions (hives, swelling, anaphylaxis) — this panel tests for those. 'Food sensitivities' marketed as IgG tests are not scientifically validated; AAAAI specifically recommends against IgG food panels. Use IgE for real allergy diagnosis.
TestWell charges $150.99 — vs $249 at Quest Direct and $400-$1200 at allergists' offices.
No fasting required. Antihistamines don't affect blood IgE results (unlike skin testing where they must be stopped).
86003 (per allergen) × number of allergens tested. Our panel covers 88 allergens, billed as a panel for HSA/FSA reimbursement.
Yes — blood allergy panels are often preferred in children with severe eczema who can't tolerate skin testing. No age minimum from a draw perspective, though most allergists wait until at least 6 months old for meaningful interpretation.
Not necessarily — positive IgE indicates sensitization, not clinical allergy. Some people have positive IgE and eat the food without reaction. Correlate with clinical history; severe positive results may warrant oral food challenge with an allergist before lifelong avoidance.
Ordered directly, the closest equivalent lists at $209.00 at Labcorp OnDemand (prices checked September 2026).
