This is a blood test for people who suspect they're allergic to cats or dogs — it is not a veterinary test for a pet's allergies. It measures IgE antibodies specific to dog and cat allergens. Human pet allergies are triggered by proteins found in an animal's dander (dead skin flakes), saliva, and urine — not their fur. Symptoms include sneezing, runny nose, itchy eyes, and asthma exacerbation. Knowing which animal you react to helps guide decisions about pet ownership, environmental control, and treatment.
Measures allergen-specific IgE antibodies to cat and dog dander in the blood, identifying or confirming a pet allergy without skin-prick testing.
Anyone with sneezing, congestion, itchy or watery eyes, or asthma symptoms around cats or dogs; people deciding whether to get a pet; and those confirming a suspected pet allergy before making housing or rehoming decisions.

2 biomarkers tested
Your Dog & Cat Allergy Test results will include values for each of the 2 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 3–5 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.
No fasting required.
The short answer
Worth it when you keep reacting around dogs or cats — congestion, itchy eyes, wheezing — and want to know for certain before rehoming a pet, choosing one, or committing to allergy treatment. One blood draw measures your IgE response to both dog and cat dander, and you don't have to stop antihistamines to take it. Note the direction: this tests YOU, not your pet.
We would rather you order the right test than the most expensive one.
This is a standard venous blood draw at a Quest or Labcorp location - walk in, no appointment needed. No fasting, and no need to stop antihistamines beforehand (the main practical advantage over skin-prick testing). $89.99 self-pay covers both dog and cat dander IgE; comparable allergist visits with skin testing typically run $150-$300+ without insurance.
An at-home draw is not recommended for this test — it needs a lab-based collection to be accurate.
The markers that matter most and what an out-of-range value can mean. Reference ranges vary by lab, age and sex.
| Marker | Typical range | What it means |
|---|---|---|
| Dog dander IgE / Cat dander IgE | Class 0 (undetectable) = no sensitization | Each allergen is reported as an IgE level with a class grade. Class 0 with symptoms points away from pet allergy (consider dust mites, mold, pollen). Rising classes indicate increasing sensitization - combined with symptoms around animals, that confirms the allergy and gives an allergist objective data if you pursue immunotherapy. |

A Dog & Cat Allergy Test test costs $89.99 at TestWell — $95.99 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 same test lists at $99.00 at Labcorp OnDemand (list prices checked Sep 12, 2026). Hospital outpatient labs typically bill around $250.00 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.
