Can IgE Allergietest help with Allergie?

An IgE allergy test (specific IgE) can help identify allergies to specific substances like pollen, pet dander, or foods. The evidence for using specific IgE in allergy diagnosis is strong (human-strong), especially when combined with clinical history and skin tests. However, a positive IgE result does not automatically mean clinical allergy – asymptomatic sensitization is possible. Total IgE is non-specific and not suitable for pinpointing allergens. Consumer tests (e.g., MyBody-X) often lack validation and clinical correlation; results should be reviewed by an allergist. Caveat: false positives and false negatives can occur. An IgE test alone is insufficient for allergy diagnosis – it is one piece of the diagnostic puzzle.
