IgE Levels Test in Delhi | Total IgE Test Specialist

IgE Test

IgE (Immunoglobulin E) is a type of antibody which is produced by the immune system. Normally, IgE helps to fight with infections. However, in some people, IgE reacts to harmless substances (like dust, pollen, or food), causing allergic reactions. The IgE blood test measures the amount of IgE in your blood. It may be a total IgE test or specific IgE test (to identify particular allergens).

Why is the IgE Test Done?

Doctors perform IgE test to:

Investigate allergy symptoms like sneezing, rashes, asthma, etc.

Diagnose conditions like:

Asthma
Allergic Rhinitis (hay fever)
Eczema
Food allergies
Allergic Bronchopulmonary Aspergillosis (ABPA)
Monitor chronic allergic conditions
Evaluate immune system disorders
Help in the diagnosis of parasitic infections

Symptoms

Frequent sneezing or nasal congestion
Chronic cough or wheezing
Skin rashes or eczema
Reactions to specific foods or insect bites
Suspected ABPA or hypersensitivity diseases

How to prepare for the test?

No fasting or any special preparation is required before the test.
You can continue taking regular medications unless instructed otherwise.

How the Test is done?

A simple blood sample is collected from a vein in your arm.
The sample is sent to a laboratory where total and specific IgE levels are measured.
The results are usually available within 1–2 days.

What the Test Measures

Total IgE: It gives an overall idea of allergic activity in the body.
Specific IgE: Identifies reaction to particular allergens e.g., dust mites, mold, foods, pets, pollens, etc.
Normal IgE levels: It vary with age, and these elevated levels may indicate an allergic or parasitic condition but need to be interpreted alongside symptoms and other test results.

Frequently Asked Questions (FAQs)

1. Does a high IgE level always mean I have an allergy?

No not necessarily, IgE may also be elevated in parasitic infections, some immune disorders, or chronic lung conditions like ABPA. Clinical symptoms are essential for interpretation.

2. Can I have normal IgE but still be allergic?

Yes. Some people have normal total IgE but show elevated specific IgE to certain allergens, and that’s why targeted allergy testing is important.

3. Is the IgE test painful or risky?

It’s a routine blood test with minimal risk. You might feel slight discomfort or bruising at the needle site.

4. What happens if my IgE is high?

Your doctor will evaluate the underlying cause such as an allergy or ABPA and may recommend further tests, avoidance strategies, or anti-allergic treatment like antihistamines or steroids.
