[New in vitro allergological diagnostic tool and its application in professional disease.]

OBJECTIVES: Molecular diagnostic is a new therapeutic approach that - allows to valuate sensitization towards a single molecule in a allergenic source and to obtain relevant information on clinical features: sensitization towards molecules as alfa amylase of wheat or lipocalins of pets, Alt a 1 of alternaria spores and Hev b 6 of latex correlates with the risk to develop asthma - has a greater sensitivity in the serum IgE identification than the whole source.
