Dog E2 (Dog Epithelium)

Dog E2 or “dog epithelium” is a test used by the IntroLab in Belgrade to measure the level of antibodies specific to dog epithelial cells in the human body. This test helps identify dog allergies and precisely determine the level of immune response.

What does the “dog epithelium” test include?

The “dog epithelium” test measures the level of Immunoglobulin E (IgE) antibodies that react to dog allergens, including:

• Epithelial cells (found in the dog’s skin and fur)
• Dog saliva
• Dander (which can be present on the skin or fur)

When a person allergic to dogs comes into contact with these allergens, their immune system recognizes these substances as harmful and produces IgE antibodies in response. The test results help doctors assess whether a dog allergy is present and its severity.

Who is the test recommended for?

The Dog E2 (dog epithelium) test is typically recommended for:

• People with allergy symptoms.
• Individuals who already know they have some allergies but want specific confirmation of a dog allergy.

How is the Dog E2 (dog epithelium) test performed?

The test is simple and usually performed via a blood test. Results are expressed in quantitative values of IgE levels, which can indicate the intensity of the reaction to dog allergens.

If the results are positive, doctors may recommend therapy or measures to reduce exposure to allergens, such as avoiding contact with dogs or using anti-allergy medications.

Understanding the Dog E2 (dog epithelium) test results

The test results are usually expressed in units indicating the concentration of IgE antibodies and are categorized as follows:

• Low level: minimal or no reaction to dog allergens.
• Medium level: possible mild to moderate reaction.
• High level: intense reaction, indicating a more serious dog allergy.

The presence of IgE antibodies does not always mean allergic symptoms will occur; a doctor will evaluate the risk in the context of the patient’s symptoms and clinical presentation.

Possible symptoms of a dog allergy

People with elevated Dog E2 test results and the presence of IgE antibodies to dog allergens may experience the following symptoms when in contact with dogs:

• Sneezing and a runny nose
• Itchy and watery eyes
• Coughing or difficulty breathing
• Rash or skin redness (especially when in contact with dog fur or skin)
• Asthma exacerbation in people who already have asthma

Alternative measures to reduce symptoms

If a test confirms a dog allergy, several strategies can help minimize symptoms:

• Removing Allergens: Regular cleaning of the home, vacuuming carpets and furniture, and using air filters can help eliminate allergens from the environment.
• Keeping the Dog Out of the Bedroom: Limiting the dog’s access to certain areas, such as the bedroom, can reduce nighttime allergen exposure.
• Maintaining Dog Hygiene: Regularly bathing and grooming the dog (preferably by a non-allergic person) can reduce the amount of allergens spread throughout the home.
• Using Medications: Doctors often recommend antihistamines, decongestants, or corticosteroids to alleviate allergy symptoms.

Can dog allergies go away?

For some people, allergic reactions to dogs may lessen over time, while for others, they may remain constant. In some cases, immunotherapy (allergy treatment through gradual exposure to small doses of allergens) can be an option for long-term symptom relief.
