ALLERGY, CAT EPITHELIUM & DANDER

The Allergy, Cat Epithelium & Dander Test is a specialized blood test used to measure specific Immunoglobulin E (IgE) antibodies against allergens present in cat skin cells (epithelium), dander, saliva, and fur. The test helps identify allergic sensitization to cats and supports the diagnosis of pet allergies, allergic rhinitis, allergic conjunctivitis, and allergic asthma.

Cat allergy is one of the most common environmental allergies. The allergy is not caused by cat hair itself but by proteins released from skin flakes, saliva, and sebaceous secretions. These microscopic particles become airborne and may remain suspended indoors for long periods, causing symptoms even without direct contact with cats.

When a sensitized person inhales these allergens, the immune system produces specific IgE antibodies. Subsequent exposure triggers the release of histamine and inflammatory mediators, leading to symptoms affecting the nose, eyes, skin, and respiratory tract.

The Cat Epithelium & Dander Allergy Test helps physicians determine whether cat allergens are responsible for allergy symptoms and supports the development of personalized allergy management strategies.

Benefits of the Test

• Detects cat-specific IgE antibodies
• Helps diagnose pet allergies
• Supports evaluation of allergic rhinitis and asthma
• Identifies environmental allergy triggers
• Assists in allergy management and prevention
• Requires only a blood sample
• Useful for both children and adults

Why Doctors Recommend This Test

Doctors may recommend this test for:

• Sneezing after exposure to cats
• Persistent nasal congestion or runny nose
• Itchy, watery eyes
• Wheezing or asthma symptoms
• Skin rash or hives after handling cats
• Suspected pet allergy
• Recurrent respiratory allergies
• Evaluation of allergy triggers

Preparation Before Test

Sample Required

• Peripheral venous blood sample

Preparation Guidelines

• No fasting is required
• Antihistamines generally do not interfere with blood IgE tests
• Inform your physician about allergy symptoms and pet exposure history
• Follow laboratory instructions before sample collection

Reporting Time

Results are generally available within 3–7 working days.

Who Should Take This Test?

• Individuals with symptoms after cat exposure
• Patients with allergic rhinitis or asthma
• Children and adults with suspected pet allergies
• Individuals with recurrent sneezing or watery eyes
• People undergoing environmental allergy evaluation

Clinical Significance

Elevated cat epithelium and dander-specific IgE levels may indicate:

• Cat Allergy
• Pet Allergy
• Allergic Rhinitis
• Allergic Conjunctivitis
• Allergic Asthma
• Environmental Allergy

Common symptoms include:

• Sneezing
• Runny nose
• Nasal congestion
• Itchy or watery eyes
• Skin rash or hives
• Cough
• Wheezing
• Shortness of breath
• Chest tightness

The presence of cat-specific IgE antibodies indicates sensitization and should always be interpreted along with clinical symptoms and exposure history.
