What Do IgE Blood Test Results Mean?
An IgE blood test measures the levels of immunoglobulin E (IgE) antibodies in your bloodstream. Elevated IgE levels may indicate the presence of allergies or parasitic infections. IgE blood test results are usually reported in international units per milliliter (IU/mL) and can vary depending on age, gender, and other factors. A immunoglobulin e blood test normal range is typically between 0 and 100 IU/mL. Abnormal results may require additional testing to determine the underlying cause. IgE blood tests are commonly used in conjunction with other allergy tests to diagnose and manage allergies.
What Is IgE Test Normal Range?
The normal IgE levels vary depending on the age and the laboratory performing the test. Please refer to the table below to check the normal range for your age.
| Age | Normal Range |
| < 1 year | 0 − 15 IU/mL |
| 1 − 5 years | 0 − 60 IU/mL |
| 6 − 9 years | 90 IU/mL |
| 10 − 15 years | 0 − 200 IU/mL |
| Adults | 0 − 100 IU/mL |
What Medical Conditions Can Cause High IgE Levels
If your test results show higher than normal serum IgE concentrations (>1,000 IU/mL), the following medical conditions might be causing your allergic tendencies:
- Allergic bronchopulmonary aspergillosis – A fungal infection of the lungs due to a hypersensitivity reaction to antIgEns of Aspergillus fumigatus after colonization into the airways.
- Allergic fungal sinusitis – A common type of fungal infection in the sinuses
- Atopic dermatitis – A chronic disease that causes inflammation, redness, and irritation of the skin.
- Human immunodeficiency virus infection (HIV) – HIV severely damages the immune system and interferes with your body’s ability to fight infections and diseases.
What Medical Conditions Can Cause Low IgE Levels
If your test results show lower than normal serum IgE concentrations, the following medical conditions might be the reasons:
- Chronic fatigue – A serious, long-term illness that affects many body systems
- Polyarthralgia – Polyarthralgia is when pain occurs in several joints of the body.
- Asthma – The air passages in the lungs become narrow due to inflammation and tightening of the muscles around the small airways.
- Chronic sinusitis – This common condition interferes with the way mucus normally drains and makes your nose stuffy. It usually occurs when the empty spaces inside your nose and head (sinuses) are swollen and inflamed for three months or longer, despite treatment.
