High Total IgE: what it means
A Total IgE result above the normal range is considered high. Here is what a raised Total IgE can point to, and when it is worth discussing with a doctor.
Reference range: ~<100 IU/mL in adults (rises in atopy); a general measure of allergic tendency, not a test for a specific allergy

What a high Total IgE can mean
- Allergic (atopic) conditions — hay fever, asthma, eczema, food allergy; commonly raised.
- Parasitic (worm) infections — often markedly high, especially with relevant travel.
- Atopic dermatitis (eczema) — can be very high.
- Allergic bronchopulmonary aspergillosis — a specific lung allergy with very high IgE.
- Rare immune disorders (hyper-IgE syndrome) — extremely high levels.
- Smoking — modestly raises IgE.
When to discuss with a doctor
Total IgE is best understood as a background measure of allergic tendency, not a test that pins down an allergy. A raised total IgE fits an atopic picture (allergies, asthma, eczema) or, with the right history, prompts thought about parasites — but it does not tell you the trigger. When identifying a specific allergen matters, allergen-specific IgE or skin-prick testing is the right test. Total IgE has particular uses in specialist settings, such as guiding the dose of certain biologic treatments for severe allergic asthma or eczema. Mediora.AI shows total IgE alongside the eosinophil count as part of the allergic picture; specific allergy testing and treatment belong with your doctor or an allergist.
How to bring a high Total IgE down
A raised Total IgE is not brought down by diet or habits. It reflects something else going on, so what actually helps is finding that cause with a doctor - the value follows once the cause is addressed.
