ALLERGY TEST
The availability of recombinant allergenic molecules has enhanced IgE antibody assay performance in a number of ways.
It has permitted an increased analytical sensitivity by supplementing extracts that are deficient in a particular allergen specificity.
There is an increase in analytical specificity when selected molecules are used to detect IgE antibodies.
Molecular allergens allow the identification of cross-reactivity.
Selected molecules define IgE antibodies as a marker of a genuine primary sensitization.
