A blood test for cat allergy — the IgE antibody to cat dander (allergen e1). For sneezing, itchy eyes, wheezing or hives around cats, or before bringing a cat home. No scratch test, no stopping antihistamines. Cat allergy is a reaction to proteins in cat skin flakes (dander), saliva and urine — chiefly Fel d 1, which clings to clothing and furniture and lingers for months after a cat is gone. This test measures the IgE antibody your immune system makes against cat dander; a raised level means you are sensitized, and together with your symptoms it tells your clinician whether the cat is a likely cause. Unlike skin-prick testing, a blood test is not affected by antihistamines, so there is nothing to stop beforehand. It is a single-allergen test: if you also react around dogs, the Dog Allergy Test or the Dog & Cat combo covers both. A negative result makes cat allergy unlikely but does not rule out non-allergic irritation from fur or litter dust. ## Biomarkers measured - Cat Dander (e1) IgE ## Price by lab | Lab | Test price | All-in (with $6 fee) | Notes | | --- | --- | --- | --- | | Quest Diagnostics | $39.99 | $45.99 | Choose at checkout; walk-in patient service centers nationwide (not NY/NJ) | | Labcorp | $39.99 | $45.99 | Choose at checkout; walk-in patient service centers nationwide (not NY/NJ) | | BioReference (NY & NJ) | $39.99 | $45.99 | New York and New Jersey orders route here automatically | Rhode Island is not served.
