What does it mean if your IgE is high?

The blood usually has small amounts of IgE antibodies. Higher amounts can be a sign that the body overreacts to allergens, which can lead to an allergic reaction. IgE levels can also be high when the body is fighting an infection from a parasite and from some immune system conditions.

Rationale: The toxin hypothesis was suggested in 1991 that allergies evolved as a defense mechanism to quickly expel and neutralize toxins. IgE mediated reactions usually cause symptoms of sneezing, cough, vomiting, diarrhea and hypotension that are suggested help expel the noxious substance from the body.

What does a high IgE level indicate?

An elevated concentration of total immunoglobulin E (IgE) is not diagnostic for allergic disease and must be interpreted in the clinical context of the patient including age, gender, travel history, potential allergen exposure, and family history. A normal concentration of total IgE does not eliminate the possibility of allergic disease.

How do you prepare an anti IgE complex?

After washing, enzyme-labeled anti-IgE antibodies are added to form a complex. After incubation, unbound enzyme-labeled anti-IgE is washed away and the bound complex is incubated with a developing agent. After stopping the reaction, fluorescence of the eluate in the well is measured.
