How to interpret and act on symptoms vs. sensitisation?
Allergen exposure is a prerequisite for developing clinical allergy/symptoms and therefore production of IgE antibodies. However, exactly when the symptoms against an allergy-causing substance develop can vary between individuals. It depends on a number of factors, including: • Type of allergy • The degree of exposure • The levels of IgE antibodies • An individuals clinical reactivity IgE antibodies can be detected very early in the blood, even before symptoms become evident, IgE sensitisation can be thus be regarded as a risk factor for developing symptoms.
