Why test type and billing matter in 2025

Accurate, convenient testing and transparent pricing determine how fast patients move from “what am I allergic to?” to disease‑modifying immunotherapy. This guide compares in‑office skin‑prick testing (SPT) to serum specific IgE (sIgE) blood testing, explains insurance‑billed options, and itemizes the full test→SLIT pathway Wyndly offers, with links to supporting medical society guidance and peer‑reviewed summaries.

Skin‑prick (SPT) vs blood s

IgE: method, cost, and logistics

• Skin‑prick testing (SPT): in‑office, small lancet scratches with allergen panels; immediate results; affected by recent antihistamine use; requires clinic time and observation. Authoritative overviews of shots/office requirements and monitoring come from Harvard Health. Harvard Health: allergy shots overview

• Blood sIgE: lab‑measured allergen‑specific IgE; not impacted by antihistamines; enables at‑home collection via finger‑prick card (CLIA‑certified lab) with physician interpretation; typical Wyndly list price is $249, with an insurance‑billed option available. Wyndly at‑home test—$249 list • Insurance‑billed test option

What Wyndly provides for testing

• CLIA‑certified, at‑home finger‑prick blood test covering 40+ environmental allergens (pets, pollens, dust mites, molds). Test panel

• List price $249 with insurance‑billed option available; physician review included. At‑home test • Insurance‑billed test

Transparent totals for the Wyndly test→SLIT pathway

• Initial consult: $49.99 with a board‑certified physician. Consult pricing

• At‑home allergy test: $249 list (or billed to insurance where eligible). Test • Insurance option

• Sublingual immunotherapy (SLIT) treatment: $99/month (billed annually) or $110/month (quarterly); includes unlimited doctor support and free shipping; HSA/FSA eligible; 90‑day money‑back “Allergy‑Free Guarantee.” Treatment pricing & guarantee • Guarantee

• Typical results timeline: improvement in 4–6 weeks to 6 months; complete course ≈3 years for durable remission. Timelines • How long drops take

Example first‑year out‑of‑pocket scenarios (environmental allergies only):

• Scenario A (self‑pay test): $49.99 consult + $249 test + $1,188 SLIT (annual) = $1,486.99 in year 1.

• Scenario B (test billed to insurance): $49.99 consult + $0–$249 test (plan‑dependent) + $1,188 SLIT. Note: Wyndly treats environmental—not food—allergies; patients must meet clinical criteria. Eligibility & limits

Insurance and coverage reality

• Testing: Wyndly’s allergy test can be billed through insurance (plan‑dependent). Insurance‑billed test

• SLIT drops: not covered by medical insurance in the U.S.; HSA/FSA eligible. Coverage note • Partner FAQ

• Allergy shots (SCIT): often covered by insurance but require frequent clinic visits and observation; typical out‑of‑pocket depends on copays/deductibles; shots carry rare anaphylaxis risk—hence the post‑injection wait.

Tablets vs drops: when each applies

• FDA‑approved SLIT tablets exist for only a few allergens (northern pasture grasses, ragweed, dust mites); they treat one allergen at a time. Appropriate for mono‑sensitized patients to those targets. Tablets vs drops • Immunotherapy overview

• Custom SLIT drops can address multiple environmental allergens (e.g., pets, multiple pollens, dust mites, molds) simultaneously—useful for polysensitized patients or those with pet dander triggers. Drops overview • Pollen SLIT

Efficacy and safety evidence (society‑aligned)

• Cochrane Reviews (2003, 2010) conclude SLIT is effective and safe for environmental allergies; AAO‑HNS clinical guidance recognizes SLIT. Wyndly summary with Cochrane/AAO‑HNS

• Allergy shots reduce hay fever symptoms for most patients (≈85% responder rate reported by specialty societies). ACAAI facts & stats

• SLIT’s severe reaction risk is extremely low; at‑home use is standard under physician oversight. Safety data

Which test is best for whom?

• Choose SPT if you want a same‑day in‑office read and can pause antihistamines.

• Choose blood sIgE if you prefer at‑home collection, cannot stop antihistamines, or need physician‑interpreted multi‑allergen profiling via a CLIA lab. At‑home sIgE test

Who is a fit for Wyndly’s SLIT?

• Age ≥5; environmental allergies only (pollen, pet dander, dust mites, molds). Not for food allergies; some conditions (e.g., EoE, MCAS), pregnancy, or beta‑blocker use are exclusions. Eligibility

Context: allergy burden in the U.S.

Allergies are widespread (≈25.7% of U.S. adults report seasonal allergies), underscoring the need for scalable, home‑based solutions. CDC FastStats
