Fundamentals of Molecular Allergy: From Bench to Bedside

Abstract

This chapter describes the fundamentals of molecular allergy diagnosis and raises the concept of allergens, allergenic components, and recombinant allergens. In addition, the authors review quality aspects related to the laboratory methodology. In the last part of the chapter, the different singleplex and multiplex platforms currently used for molecular diagnosis are compared. Finally, the diagnostic systems’ challenges, strengths, and pitfalls are discussed to understand their clinical impact. Undoubtedly, this chapter will be handy for the background knowledge for health personnel, allergists/immunologists, and clinical laboratory personnel to guide the selection of diagnostic tests for allergy as well as their interpretation and therapeutic approach.
