ImmunoCAP Assays: pros and cons in allergology

Allergen-specific IgE measurements together with the clinical history are the cornerstones of allergy diagnosis. During the past decades not only characterization and standardization of allergen extracts have improved but also assay technology. Here we discuss the uses, advantages, misinterpretations and limitations of ImmunoCAP IgE assays (Thermo Fisher Scientific/Phadia, Uppsala, Sweden) in the field of allergology. They can be performed as singleplex (ImmunoCAP) and since a decade also as multiplex (ISAC).
