There has been considerable progress in the area of molecular allergology over the last few years.

A better understanding of allergen components and their role in the mechanisms of sensitisation and tolerance induction leads to a more targeted management of inhalant- and food allergy.

A significant proportion of house dust mite sensitised patients may be missed if using only group 1 and group 2 allergens in the diagnostic work-up.
