How to prepare for IgE Allergie Labor

Preparation for an IgE allergy lab test depends on the specific test method. For specific IgE blood tests, no special diet or medication pause is generally required, as IgE antibodies are not acutely affected by food intake. However, antihistamines can suppress skin test reactivity – for skin prick tests, these should be discontinued 3–7 days beforehand (only after consulting your doctor). Fasting is not necessary for total or specific IgE blood draws. Important: Elevated IgE levels indicate sensitization, not necessarily clinical allergy. Diagnosis requires correlation with symptoms and, if needed, provocation tests. The provided context lacks any information on IgE lab preparation. Therefore, this answer is based on standard medical practice. Evidence: practice (standard medicine). Sources: none from context.
