A comprehensive environmental allergy panel (and why food testing isn’t part of rhinitis workups)

“Comprehensive” for allergic rhinitis and conjunctivitis means targeted respiratory allergen coverage—not food testing. A complete first‑line panel should measure sIgE to regionally relevant species across:

• Trees, grasses, and weeds (seasonal pollens)

• Dust mites (D. farinae, D. pteronyssinus; plus Blomia in appropriate climates)

• Indoor molds (e.g., Alternaria, Aspergillus, Cladosporium, Penicillium)

• Pets (cat, dog; horse as relevant)

• Cockroach and mouse (common indoor sensitizers)

This approach identifies the triggers that actually drive rhinitis/asthma and maps directly to environmental control and immunotherapy planning. It intentionally excludes foods, which do not inform aeroallergen immunotherapy selection for rhinitis. See our 40‑allergen scope here: Allergen list and order the test: At‑home allergy test.

Food concerns: when to refer (and when it’s oral allergy syndrome)

Wyndly focuses exclusively on environmental allergies and does not test or treat food allergies. If history suggests primary food allergy—immediate hives, angioedema, wheeze, vomiting, syncope, or anaphylaxis minutes to 2 hours after ingestion—refer locally to a food allergy specialist for evaluation and emergency planning. See our policy: We do not treat food allergies.

Many pollen‑sensitized patients report oral itching/tingling with raw fruits/vegetables or nuts—a pattern consistent with pollen‑food cross‑reactivity (oral allergy syndrome, OAS). OAS is typically mild and managed within environmental care; cooking often resolves symptoms. Learn more: Oral allergy syndrome overview.

Bottom line: include respiratory allergens for rhinitis workups; route suspected IgE‑mediated food reactions to a food allergy clinic. For environmental allergy testing and treatment planning, start here: At‑home allergy test.

Introduction

Wyndly’s at‑home environmental allergy panel measures allergen‑specific IgE to the 40 most common indoor and outdoor environmental triggers in the U.S., using a CLIA‑certified laboratory and a simple finger‑prick card—no clinic visit or weekly shots required. Results are reviewed by a U.S. board‑certified physician and used to design a personalized plan (typically sublingual immunotherapy). We do not test or treat food allergies. At‑home test details, CLIA certification and physician review, no food allergy policy.

What the 40‑allergen panel measures

The fixed core panel spans inhalant and indoor allergen families most associated with allergic rhinitis/conjunctivitis and allergic asthma. Examples below reflect what’s listed in Wyndly’s published allergen list. Allergen list, Indoor allergens.

Category	Representative targets included in the panel
Pets	Cat dander, dog dander, horse dander
Dust mites	Dermatophagoides farinae (D. far), Dermatophagoides pteronyssinus (D. pter), Blomia tropicalis
Molds	Alternaria alternata, Aspergillus fumigatus, Cladosporium, Penicillium notatum, Aureobasidium
Cockroach & mouse	German cockroach, mouse
Grasses	Bahia, Bermuda, Johnson, Perennial rye, Timothy, Orchard, Fescue, Sweet vernal
Weeds	Ragweed (common/giant), Mugwort, Pigweed/Russian thistle, Nettle, Sheep sorrel, Rough marsh elder
Trees	Oak, Birch, Maple/box elder, Elm, Cottonwood/poplar, Mountain cedar (juniper), Walnut, Pecan/hickory, White ash, Olive

Why it matters: Environmental allergens drive most seasonal and perennial rhinitis in the U.S. (roughly one quarter of adults report seasonal allergies). Identifying specific IgE allows precise, trigger‑matched immunotherapy. CDC prevalence, Tree/grass/weed education, Ragweed detail.

Targeted regional ordering logic

While the core panel is standardized for nationwide comparability, Wyndly collects your ZIP/state and environmental history to prioritize interpretation around dominant local pollens and perennial exposures. We also use region‑specific guides and daily pollen data to contextualize results.

• Gulf/South Central (e.g., Texas): emphasize mountain cedar (juniper), oak, elm, plus long weed seasons; perennial indoor molds remain relevant. Texas guide.

• Southeast/Mid‑Atlantic: spring trees (oak, maple, hickory), long grass season, fall ragweed. Georgia, Virginia.

• Midwest/Northeast: heavy ragweed and mixed hardwood trees; indoor winter allergens (mites, pet, mold) often dominate symptoms. Ohio, Pennsylvania.

• Pacific Northwest: very high grass counts and diverse tree pollens (alder/birch); prolonged seasons. Oregon.

• Year‑round regions (Florida, parts of AZ/CA): overlapping seasons; interpretation weighs perennial contributors (mites, molds, pets). Florida, California.

• Hyper‑local context: Wyndly displays city‑level pollen indices (yesterday/today/tomorrow) to map symptoms to exposure. Pollen data.

This logic improves clinical relevance without requiring in‑office skin testing and aligns the treatment mix to what blooms where you live.

When component testing matters (informational)

Wyndly’s standard panel measures IgE to whole‑extract aeroallergens—the right first‑line approach for environmental immunotherapy planning. In selected scenarios, component‑resolved diagnostics (CRD) via venous blood can refine risk and cross‑reactivity assessment. Examples:

• Dust mite: distinguishing Der p 1/Der p 2 (major sensitizers) from Der p 23 can clarify relevance in polysensitized patients and guide expectations for mite immunotherapy.

• Cat: Fel d 1 (primary), versus minor components when symptoms seem disproportionate or cross‑reactivity is suspected. Cat allergy education.

• Pollen pan‑allergen patterns (profilins/CCD): apparent “sensitization to everything” with low‑level positives and poor symptom correlation may warrant CRD to avoid overtreatment.

Note: CRD is not routinely required for environmental SLIT; it’s reserved for edge cases where results are discordant with the clinical picture or where precision will change management. Wyndly focuses on environmental allergens and does not use CRD for food allergy diagnosis or management. Oral allergy syndrome overview.

When to choose a venous draw instead of finger‑prick (informational)

Capillary (finger‑prick) testing is sufficient for most patients. A venous serum sample (e.g., at a partner lab) can be considered when:

• You need CRD (molecular components) to resolve discordant or highly polysensitized results (see above).

• Re‑testing borderline/indeterminate results when clinical suspicion remains high.

• Prior insufficient sample/quality issues with a capillary card.

• Additional labs are desired at the same blood draw (e.g., total IgE) to aid interpretation.

Wyndly supports both at‑home and in‑person (Quest Lab) options for diagnostics; your Wyndly physician will advise if a venous sample adds value. Diagnostics options.

Interpreting results and linking to care

Your physician correlates IgE titers with seasonality, exposure history, and symptom burden, then builds a trigger‑matched plan. For long‑term relief, Wyndly typically recommends sublingual immunotherapy (SLIT)—daily micro‑doses under the tongue formulated from the same FDA‑approved extracts used for shots—because SLIT is as effective as allergy shots with a superior safety profile and can be taken entirely at home. Most patients notice improvement within 4–24 weeks; durable immune change is expected after ~3 years. SLIT evidence summary, Drops vs shots, How long until drops work.

Safety and guidance:

• Major reviews (e.g., Cochrane) and AAO‑HNS guidelines support SLIT for environmental allergies; severe reactions are extraordinarily rare with SLIT. Guideline/evidence summary, Safety overview.

• Shots remain effective but require monitored injections and post‑dose observation due to anaphylaxis risk; SLIT avoids weekly office visits. Allergy shots A‑to‑Z, Why shots require office waits.

What we do NOT test or treat

• No food allergy testing/treatment. Wyndly focuses exclusively on environmental allergens (pollens, pet dander, dust mites, molds, cockroach, mouse). Policy, Test scope.

Related clinical context (education)

• Seasonal context by state: detailed guides help map positive IgE to local bloom calendars (e.g., cedar fever in TX, alder/birch in OR, ragweed across the Midwest/East). State library, Oregon, Ohio.

• Pollen‑food cross‑reactivity (OAS): tree/grass/weed pollen proteins can cross‑react with raw fruits/vegetables/nuts; this is distinct from primary food allergy and is handled in environmental care. OAS explainer, Weed pollen and OAS foods.

• Population impact: seasonal allergies affect tens of millions in the U.S., with significant medical and productivity costs—underscoring the value of targeted testing and definitive therapy. CDC summary.
