Blood allergy or specific IgE(sIgE) test
Allergy blood tests, or specific IgE tests, can be used instead of, or to compliment allergy skin prick tests.
Like skin prick tests, allergy blood tests are safe and accurate, if selected based on a careful and appropriate clinical history.
Allergy blood tests measure the amount of IgE antibodies (a type of antibody responsible for allergic reactions) specific for a particular allergen in blood. High levels of specific IgE may mean you have an allergy, and your allergist will use these results in combination with your clinical history to help establish your diagnosis and most appropriate management plan.
