Immunoglobulin E
Immunoglobulin E (IgE) is an antibody class involved in the body's response to allergens — pollen, dust, certain foods — and parasitic infections. Most people have low total IgE in circulation; sensitized individuals can have markedly higher levels.
Why it matters: Total IgE is a screening signal for atopic tendency — the underlying predisposition to allergic reactions. Higher-than-typical levels are common in people with hay fever, asthma, eczema, or food sensitivities.

What is Immunoglobulin E?
Immunoglobulin E (IgE) is an antibody class involved in the body's response to allergens — pollen, dust, certain foods — and parasitic infections. Most people have low total IgE in circulation; sensitized individuals can have markedly higher levels.
What might a high or low Immunoglobulin E mean?
Total IgE is a screening signal for atopic tendency — the underlying predisposition to allergic reactions. Higher-than-typical levels are common in people with hay fever, asthma, eczema, or food sensitivities.
What can affect Immunoglobulin E?
It may be higher with: Allergies, Parasitic infections, Atopic dermatitis. It may be lower with: Immunosuppressive therapy, CVID.
