What is an
Allergy Screen (Shellfish) Blood Test?

Our shellfish allergy screen provides an analysis of eight commonly eaten shellfish which can cause IgE-mediated allergies. You'll also get a total measure of your immunoglobulin E, which is often raised if you have an IgE-mediated allergy.

Who should
take this test?

Our test is ideal as part of an initial investigation screen if you have signs of IgE-mediated allergies, such as hives, redness of the skin, vomiting, and lip or facial swelling, which develop quickly after exposure to a shellfish allergen.

Immunoglobulin E Immunoglobulins or antibodies, play an important role in the immune system and help fight against harmful bacteria and viruses in the body. There are five classes of antibodies and several subclasses. In those that have an allergy, their immune system overreacts to a harmless allergen (such as food, grass or animal dander) by producing IgE. This reaction usually causes irritation to the nose, lungs, throat and skin. The allergen-specific IgE antibody test is used to check for an allergy to a specific allergen. It measures the amount of IgE antibody in the blood targeted for a suspected allergen.
