Total IgE Test: normal range & what your result means
Written & medically reviewed by Dr. Sanjay Anbu, MBBS · Last reviewed
Medically reviewedIgE is the antibody involved in allergies. A total IgE test measures the overall amount in your blood; it can be raised in allergies and worm infections but cannot say exactly what you are allergic to.
About the test
Why the IgE test is done
- Allergic symptoms — sneezing, asthma, eczema or hives
- Suspected worm infection (common in India)
- Raised eosinophils on a blood count
Reference range
Typical adult range
| Measure | Typical adult range |
|---|---|
| Typical adult | Below about 100–150 IU/mL |
| Note | Children’s ranges vary with age |
Typical adult range; labs differ — use the range on your report. Ranges also vary with age, sex, pregnancy and the method used. Your doctor interprets the result alongside your symptoms and history.
Results
What a HIGH result can mean
- Allergic conditions — allergic rhinitis, asthma, eczema
- Worm (parasitic) infections
- Rarely, immune system disorders
- A high level does not identify the allergen — specific IgE or skin tests do that
Results
What a LOW result can mean
- Usually not a concern
- A normal IgE does not rule out allergy
Preparation
Before the test
- No fasting needed
- Tell your doctor about recent worm treatment or allergy medicines
Red flags
When to get urgent help
- Swelling of the lips, tongue or throat, or difficulty breathing — call your local emergency number (108/112 in India)
- An asthma attack not improving with usual inhaler

Frequently asked questions
What does high IgE mean?
It usually suggests an allergic tendency or a parasitic (worm) infection. Your doctor interprets it with your symptoms and other tests.
Can a total IgE test tell what I am allergic to?
No. It only measures the total amount. Specific IgE blood tests or skin-prick tests identify individual allergens.
Why do worms raise IgE?
The immune system uses IgE to fight parasites, so worm infections can raise IgE and eosinophils.
