Cat Dander Allergy
Cat Dander Allergy Test
Our immune system often mistakes common things for harmful substances and starts producing antibodies to combat them, causing more harm than good. Similar is the case with cat dander (cat’s dead skin, hair, saliva, and urine), where our immune system takes it as a severe allergen and starts producing antibodies against it.
A cat dander allergy test measures the allergy-causing antibodies (IgE) produced by our body in response to contact with a cat’s dander.Â

Test preparation:
A cat dander allergy can be tested in two ways.
- Blood test – A healthcare provider will collect a few mL of your blood sample by inserting a small needle into a vein in your arm and gets it tested to see for IgE antibodies.
- Skin prick test – A healthcare provider will clean the test area with alcohol or iodine. It is usually your forearm or upper back region. The allergen is now applied to your skin, and the skin is lightly scratched to allow the allergen to come into contact with your body fluids.
Please tell your healthcare provider if you are taking any medicines such as anti-allergy or anti-histamines, corticosteroids, anti-inflammatory, etc., before taking the above tests.
Interpretation of test results:
An allergy is typically indicated by a high level of IgE antibodies specific to cat dander.

FAQs
What is the turnaround time (TAT) for the cat dander allergy test?
The test results for cat dander allergy are usually available within 4 – 6 working days after the sample collection. However, it could take a little longer at times.
Are there any risks associated with cat dander allergy test?
If it is a blood test, then there will be a negligible risk such as feeling a slight sting or bruise at the site of sample collection. It usually resolves within a few minutes to a couple of hours.
If it is a skin prick test, and you are allergic to a specific allergen, then you may experience an allergic reaction within 15 to 20 minutes of allergen contact during the test. Nonetheless, the test is performed in the presence of a healthcare professional, and the symptoms are effectively monitored as soon as they appear.
Is it necessary that if I am allergic to cats, I will be allergic to all pets?
