Measures your total immunoglobulin E — the antibody behind allergic reactions — as a first screen for an allergic tendency, asthma or eczema work-ups, and certain parasitic or immune conditions. Immunoglobulin E (IgE) is the antibody class that drives allergic reactions: when it binds an allergen on mast cells, they release histamine. A total IgE test measures the overall amount in blood rather than IgE to any particular allergen. A high level supports an allergic tendency (atopy) and is common in allergic asthma, eczema, hay fever and food allergy; markedly high levels are also seen in parasitic infections and a few rare immune disorders, and the value is used to dose the anti-IgE medication omalizumab. A normal total IgE does not rule out allergy to a specific trigger — for that, allergen-specific IgE panels are the next step. It is the basic serum IgE level a physician orders before, or alongside, targeted allergy testing. ## Biomarkers measured - Immunoglobulin E (IgE), Total ## Price by lab | Lab | Test price | All-in (with $6 fee) | Notes | | --- | --- | --- | --- | | Quest Diagnostics | $29.99 | $35.99 | Choose at checkout; walk-in patient service centers nationwide (not NY/NJ) | | Labcorp | $29.99 | $35.99 | Choose at checkout; walk-in patient service centers nationwide (not NY/NJ) | Rhode Island is not served.
