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

Who Is This For?
People experiencing unexplained digestive issues, skin problems, or chronic fatigue that may be food-related. Anyone with known allergies who wants comprehensive mapping of their triggers. Parents investigating potential food sensitivities in children. People considering an elimination diet and wanting data to guide which foods to remove.
What's Included
Preparation Required
No fasting required. Continue eating your normal diet for at least 2–4 weeks before testing — avoiding suspected trigger foods can cause false negatives. Inform the clinic of any antihistamines or immunosuppressants you're taking, as these can affect results.
Biomarkers Tested
6A group of proteins in blood including antibodies (immunoglobulins), transport proteins, and enzymes. Elevated globulin can indicate chronic infection, inflammation, or blood cancers. Calculated by subtracting albumin from total protein.
Major allergen in cat skin and saliva; primarily sensitized to cat.
Cross-reactive allergen that may be caused by other animals; not primarily sensitized to cat.
Cross-reactive allergen that may be caused by other animals; not primarily sensitized to cat.
Cross-reactive allergen that may be caused by other animals; not primarily sensitized to cat.
Immunoglobulin E (IgE) is a protein associated with allergic reactions that is normally found in very small amounts in the blood. IgE functions as part of the body's immune system (its defence against 'intruders').
