Allergy blood tests, or specific IgE tests, can be used instead of, or to complement, allergy skin prick tests. Like skin prick tests, allergy blood tests are safe and accurate when chosen based on a careful and appropriate clinical history.

These tests measure the amount of IgE antibodies (a type of antibody responsible for allergic reactions) specific to a particular allergen in the blood. High levels of specific IgE may indicate an allergy. Your allergist will use these results, along with your clinical history, to help establish your diagnosis and the most appropriate management plan.
