In these tests, peanut allergens are measured in foods by immunoassay with human IgE antibodies. [17] In 2003 a monoclonal antibody-based enzyme immunoassay was developed to monitor the major peanut allergen, Ara h 1. Unlike other assays, this test provides quantitative measurements of allergen levels in food products in absolute units. [2]
