About Allergy screen (shellfish)

What is the Allergy Screen (Shellfish)?

Immunoglobulin E (IgE) is a type of antibody typically produced by the immune system to protect against pathogens such as bacteria, viruses and parasites. Some people have a hyperactive immune system, which produces IgE in response to benign allergens from other sources, such as shellfish. This process mistakes harmless molecules for pathogens, causing an allergic reaction. Allergies are thought to affect over 1 in 4 people in the UK at some point during their lifetime. 

Why take the test?

This test is used to identify potential nut allergies. It measures the levels of IgE in the blood, along with screening for reactions to a variety of shellfish. The test will detect and identify shellfish allergies.
