Why component results matter for cat and dog allergy care
Component‑resolved diagnostics (CRD) break a pet dander result into individual proteins (for cats: Fel d 1; for dogs: Can f 1, Can f 2, Can f 5, etc.). If you already have a CRD report from another lab, Wyndly physicians will review it and use it to fine‑tune your treatment plan. If you don’t, that’s okay—our standard at‑home blood test uses specific IgE to whole extracts (cat and dog dander) and is sufficient to start care. Existing test review • At‑home test
-
CRD helps confirm which pet proteins are driving symptoms and can inform education and avoidance advice.
-
Your sublingual immunotherapy (SLIT) still targets the relevant pet dander(s); component results are used to prioritize focus and set expectations, not to gate access to care. Wyndly treats environmental allergies only (pets, pollen, dust, mold), not food. What we treat
-
Most SLIT patients notice improvement between 4 weeks and 6 months, with long‑term benefit after ~3 years of consistent therapy. Timelines
What the common pet components mean (at a glance)
-
Fel d 1 (cat): The major cat allergen and the most clinically relevant target in cat allergy. Wyndly builds cat‑focused plans when your history and testing point to cat dander, with or without component detail. Cat allergy care • Fel d 1 explained in care context
-
Can f 1 / Can f 2 (dog): Dog lipocalin components frequently associated with dog dander allergy.
-
Can f 5 (dog): A distinct dog component; if reported on your CRD, we incorporate it in counseling and plan focus.
Note: Wyndly’s standard diagnostics quantify IgE to whole pet dander; component results from outside labs are welcomed but not required to start SLIT. Our test
How Wyndly uses your component results
-
Personalize focus: We confirm the most relevant pet(s) and emphasize those allergens in your plan alongside any pollen, dust mite, or mold triggers you have. Wyndly does not charge per allergen. Pricing and scope
-
Set expectations: Higher reactivity to a major component often correlates with more persistent symptoms; we’ll discuss timelines, home strategies, and realistic goals. Pet allergy guidance
-
Educate and coach: Component patterns inform practical tips (cleaning routines, HEPA usage, bedroom controls), but SLIT remains the core long‑term solution. Pet allergy guide
Example: how we translate reports into care
| Example CRD or extract result | What it means | Wyndly plan you’ll receive |
|---|---|---|
| Fel d 1 very high; dog dander negative | Cat is the primary driver | Cat‑focused SLIT; cat‑specific home controls; typical improvement in 4–24 weeks |
| Dog Can f 1 and/or 2 positive; cat negative | Dog is the primary driver | Dog‑focused SLIT; pet hygiene/room zoning; timeline 4–24 weeks |
| Fel d 1 high + dog dander positive (with or without components) | Both pets are relevant | Multi‑allergen SLIT (cat + dog) at no per‑allergen fee; counseling on cross‑exposures |
| No component report, whole‑extract cat/dog positive | Components not required | Start SLIT based on extract + history; add components later only if clinically useful |

FAQs
Do you accept Can f 5?
Yes. We accept and interpret Can f 5 (and other dog components) from external labs. Components are optional; our standard pathway uses whole‑extract dander results plus your history to build SLIT. If you have a Can f 5 value, upload it with your report. Upload now
Do you perform component testing in‑house?
Our default at‑home test measures specific IgE to whole extracts (e.g., cat and dog dander). If you bring component results (Fel d 1, Can f 1/2/5), we incorporate them into your plan. About our test
Will components change my allergy drops?
Components help us prioritize focus and counseling. Your SLIT uses clinically supported dosing of the relevant environmental allergens and follows major practice guidance. Our immunotherapy approach • Consult first
How fast will I feel better?
Most sublingual patients notice improvement between 4 weeks and 6 months; full, durable benefit usually requires ~3 years. How long SLIT takes
Do you treat food allergies?
No. Wyndly treats environmental allergies (pets, pollen, dust mites, mold) and does not treat food allergies. What we treat
