Total IgE
- Sample Type
- Standard
- Fasting
- No
- Unit
- IU/mL
Immunoglobulin E (IgE) is an antibody linked to allergic reactions and defense against parasites. In an Allergy Profile, the Total IgE provides an overview of the body's 'atopic' status—the general genetic predisposition to develop allergies. While it doesn't tell you what you are allergic to, it indicates the likelihood that symptoms are allergy-driven rather than irritant-driven.

Why Context Matters
Total IgE is a non-specific test. A person can have severe specific allergies (like to peanuts) but have a normal Total IgE. Conversely, smokers or individuals with parasitic infections can have very high Total IgE levels without having any traditional environmental or food allergies.
Lab ranges are statistical averages, not biological laws. "Normal" for a 20-year-old male isn't normal for a 60-year-old female.
