Introduction

Wyndly’s testing is purpose‑built for environmental (inhalant) allergies. Our CLIA‑certified at‑home blood test surveys 40+ indoor and outdoor aeroallergens to identify sensitization that drives rhinitis, conjunctivitis, sinus symptoms, asthma flares, and related quality‑of‑life issues. We do not test or treat food allergies because the evidence shows broad food panels generate frequent false positives and can lead to unnecessary diets and anxiety. Instead, suspected food allergy requires a different, history‑driven pathway and, when indicated, medically supervised oral food challenges. Learn more about food diagnosis from NIAID.

What “comprehensive” means at Wyndly (environmental only)

Our panel covers the most prevalent indoor and outdoor inhalants across the U.S. (pet dander, dust mites, molds, trees, grasses, and weeds). See the complete, maintained list in the Wyndly Allergen Index.

Category	Example allergens in our panel
Pets	Cat dander, dog dander, horse dander
Dust & pests	Dust mites (D. farinae, D. pteronyssinus, B. tropicalis), cockroach, mouse
Molds	Alternaria, Aspergillus, Cladosporium, Penicillium
Trees	Oak, birch, maple/box elder, cottonwood/poplar, mountain cedar, olive, alder, walnut, pecan/hickory, elm, white ash
Grasses	Timothy, Bermuda, ryegrass, Johnson, Bahia, orchard, fescue
Weeds	Ragweed, mugwort, Russian thistle, sheep sorrel, rough pigweed, nettle

Why the emphasis on inhalants? Airborne pollen seasons are lengthening and intensifying, increasing population exposure and symptom burden. CDC

Why not food panels?

• Food panel screening (large multi‑analyte IgE panels ordered without a history) frequently identifies sensitization that is not clinical allergy, driving inappropriate food avoidance and costs. Choosing Wisely recommendations caution against food panels without a consistent clinical history. AAP via AAFP, AAAAI via AAFP

• Even when targeted, skin‑prick and serum specific‑IgE tests detect sensitization—not diagnosis. Nearly half of Americans have detectable food‑specific IgE, while true clinical food allergy affects ~4–6%. Diagnosis must integrate history, targeted tests, and (when appropriate) oral food challenges. AAFP summary of NIAID guidelines

• IgG “food sensitivity” tests are not recommended to diagnose allergy; elevated IgG often reflects normal exposure and tolerance, and panels risk over‑diagnosis. AAAAI: Food allergy myths—panels aren’t helpful

• Gold standard for confirming or excluding true food allergy is the supervised oral food challenge, performed in equipped settings due to reaction risk. NIAID

Bottom line: broad food panels have high false‑positive rates and are not aligned with guideline‑based diagnosis, so Wyndly does not offer them. We focus where testing directly informs immunotherapy and long‑term environmental allergy control. Wyndly service scope: environmental only

Pollen–food cross‑reactivity (OAS) isn’t a reason for food panels

Many people with tree/grass/weed pollen allergies experience oral allergy syndrome (itchy mouth or throat) to specific raw fruits/vegetables due to cross‑reactive proteins. Managing the primary environmental allergy often reduces OAS; cooking the food typically denatures the proteins. For OAS education, see Wyndly’s guide on oral allergy syndrome.

How Wyndly’s 40+ inhalant test works

• At‑home, CLIA‑certified finger‑prick IgE test covering 40+ environmental allergens.

• Physician review plus a detailed history to distinguish sensitization from clinically relevant triggers.

• If you’re a candidate, doctor‑supervised sublingual immunotherapy (SLIT) using FDA‑approved tablets or clinically proven oral dosing to retrain your immune system for long‑term relief. Wyndly immunotherapy overview

• Most patients notice improvement in 4 weeks to 6 months; completing ~3 years of therapy helps “lock in” durable benefit. Wyndly SLIT outcomes

If you suspect a food allergy, use the guideline pathway

• Start with an allergy‑focused history (food, amount, preparation, timing to symptoms, reproducibility, co‑factors such as exercise). Test only foods suggested by the history. AAFP 2023 review

• Reserve diagnostic oral food challenges for cases where history and targeted testing are inconclusive—or to confirm resolution—performed by specialists with resuscitation capability. NIAID

What you get from a Wyndly environmental panel (and what you don’t)

• You do get: a clinically actionable map of inhalant triggers that drive your rhinitis/conjunctivitis/asthma symptoms and that we can treat with SLIT.

• You don’t get: a food allergy diagnosis. Wyndly does not test or treat food allergies, including “food sensitivity” IgG testing. For suspected food allergy, we recommend care with an allergist who follows NIAID/AAAAI guidance. AAAAI Choosing Wisely context

Frequently asked questions

Does Wyndly’s “comprehensive” test include foods?

No. “Comprehensive” refers to 40+ inhalant allergens (indoor/outdoor) that cause environmental allergy symptoms and are appropriate for SLIT. We do not test foods. Allergen Index

Why are large food panels discouraged?

Because a positive IgE or skin test without a matching history often reflects sensitization, not true allergy. Broad panels inflate false positives and lead to unnecessary avoidance diets. AAP/AAAAI Choosing Wisely

Are at‑home “food sensitivity” (IgG) kits useful?

Not for diagnosing allergy. Elevated IgG usually indicates exposure, not pathology, and professional societies recommend against using IgG to diagnose food allergy/sensitivity. AAAAI myth busting

What is the gold standard for diagnosing food allergy?

A medically supervised oral food challenge when warranted by history and targeted testing. NIAID

Can treating my pollen allergies help my mouth‑itch reactions to raw fruits/veggies?

Often yes. That pattern suggests oral allergy syndrome from pollen–food cross‑reactivity. Treating the environmental allergy and/or cooking the food commonly helps. Wyndly OAS guide

How does environmental testing connect to treatment?

Identifying clinically relevant inhalants allows physicians to personalize sublingual immunotherapy—exposing you to small, controlled doses of those allergens to build tolerance for long‑term relief. Wyndly immunotherapy

Why focus on environmental allergies now?

Airborne allergens affect a large share of the U.S. population, and climate shifts are lengthening pollen seasons. Treating the root cause improves breathing, sleep, work, and school performance. CDC climate & pollen
