Test
Method
ImmunoCAP™
Method Description
ImmunoCAP™ assays are based on binding of allergen-specific IgE antibodies in serum to allergen (extract or allergen molecule) coupled in excess to a solid phase. Bound IgE is subsequently detected with enzyme-labeled anti-human IgE, where the fluorescence intensity is proportional to the amount of allergen-specific IgE.
Platform
Phadia

Clinical Utility
In patients suffering from extrinsic asthma, hay fever or atopic eczema, symptoms develop after exposure to specific allergens. This immediate (atopic or anaphylactic) type of allergy is a function of a special type of serum antibodies belonging to the IgE class of immunoglobulins.
Clinician must determine clinical significance of specific IgE result after correlation with clinical exam and history. Detectable levels are present in patients with allergic disease and in approx. 15% of symptomatic healthy persons. Some with classic atopic symptoms may not have detectable levels. Specific IgE may decrease with time and lack of exposure to allergens.
