Test information

Total IgE: This assay is commonly requested in patients with atopy or suspected allergies. ‘Atopy’ is defined as the genetic predisposition to produce greater amounts of IGE. These individuals are more likely to have childhood eczema, asthma or hay fever. The results of total IgE must be interpreted in relation to the clinical history. High levels of total IgE may be seen in patients with personal or family history of atopy particularly atopic dermatitis (eczema), hay fever or asthma.
