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.

A Total IgE (Immunoglobulin E) test costs $29.99 at TestWell — $35.99 all-in when ordered alone, because the $6 lab processing fee is charged once per order, with no draw fee or physician fee added. Hospital outpatient labs typically bill around $110.00 self-pay for the same test, and often more. With insurance, what you pay depends on your deductible and your plan's negotiated rate; TestWell's price is fixed before the draw and is HSA/FSA-eligible.
