What is the Total IgE Test?
The Total Immunoglobulin E (Total IgE) test measures the overall level of IgE antibodies in your blood. IgE is a type of antibody that the immune system produces in response to allergens and certain parasites. Elevated IgE levels are a strong indicator of allergic conditions or parasitic infections. It is different from specific IgE testing, which identifies reactions to individual allergens like dust, pollen, or food.
Why is the Total IgE Test Done?
- To investigate allergic conditions such as asthma, allergic rhinitis (hay fever), eczema, or hives
- To screen for parasitic infections, which are a common cause of high IgE in Bangladesh
- To evaluate patients with recurrent or unexplained allergic reactions
- To assess patients before starting allergen immunotherapy (allergy shots)
- To diagnose a rare condition called hyper-IgE syndrome
Normal Total IgE Levels
| Age Group | Normal Total IgE Level |
|---|---|
| Adults | Below 100 IU/mL (some labs use below 150 IU/mL) |
| Children (varies by age) | Generally lower than adult ranges |
There is no single universal normal range — labs vary slightly. Very high levels (above 1,000 IU/mL) strongly suggest allergic disease or parasitic infection. A normal total IgE does not completely rule out allergy, as some allergic individuals have normal total IgE but elevated specific IgE.
How to Prepare for the Total IgE Test
- No fasting is required
- Inform your doctor about allergy medications, antihistamines, or steroids you are taking — these can suppress IgE-related responses
- Inform the doctor if you have asthma, eczema, known allergies, or recent parasitic infections, as these are clinically important context
- Avoid heavy allergen exposure before the test if possible
- A simple blood sample is drawn from a vein in your arm
