IgE (total)
IgE (total) is a type of antibody that mediates allergic reactions and defense against parasites. Total IgE tells the overall level, but not what you are allergic to.
| Rating | Range | What it means |
|---|---|---|
| Good | below 100 kU/L | Within range. |
| Worth improving | 100 – 200 kU/L | Mildly elevated — atopy? |
| Talk to a doctor | 200 kU/L and above | Elevated — allergic predisposition; context. |
Why it matters
EAACI: elevated indicates atopy; does not prove a specific allergy.
If it’s low
Low IgE is of no clinical significance.
If it’s high
Elevated IgE often accompanies allergic diseases (hay fever, asthma, atopic dermatitis) or infection with parasites. On its own it is not a diagnosis — it guides further tests.
What to do
Total IgE is not a lifestyle marker. With allergic symptoms, arrange specific allergen tests and work-up with a doctor.
