Molecular Allergen-Specific IgE Assays as a Complement to Allergen Extract-Based Sensitization Assessment
http://dx.doi.org/10.1016/j.jaip.2015.09.013
Molecular allergen- based component-resolved diagnostic IgE antibody tests have emerged in the form of singleplex assays and multiplex arrays. They use both native and recombinant allergen molecules, sometimes in combination with each other, to supplement allergen extract-based IgE antibody analyses. The total number of available allergenic molecules has reached a diagnostically useful level; however, more molecules are needed to cover all the clinically important allergen specificities. Thus, for the foreseeable future, molecular allergen-specific IgE analyses will remain a supplement for initial allergen extract-based IgE antibody analyses in the diagnostic workup of the allergic patient. As a spin-off, it will enable manufacturers to improve the quality of extracts for in vitro testing. The 2 most exciting diagnostic developments linked to component-resolved diagnostic tests are the possibility to increase diagnostic sensitivity by the inclusion of allergens that are underrepresented in the current extracts and in vitro assays and to increase the diagnostic specificity by taking the information on allergen cross-reactivity into account. Particularly the latter application is still under development. This requires additional studies on the clinical relevance of serological cross-reactivity. 2015 American Academy of Allergy, Asthma & Immunology ( J Allergy Clin Immunol Pract 2015;3:863-9)
