Cat Allergy Test with Reflex to Components by Quest Diagnostics

Measures IgE antibodies to cat dander allergens to help determine cat allergies.

Additional Information

This blood test measures immunoglobulin E (IgE) antibodies to cat dander allergens. A positive result indicates the presence of IgE antibodies, suggesting a possible allergic reaction. However, further evaluation by a healthcare provider is necessary for a definitive diagnosis. The test may include reflex testing to identify specific cat dander components (Fel d 1, Fel d 2, Fel d 4, Fel d 7) if the initial result is abnormal, providing more detailed diagnostic information at no extra cost. This helps determine the specific allergen causing the reaction and guides appropriate treatment.
