How are IgE Allergietest and Haut related?

IgE allergy tests (blood tests) measure specific immunoglobulin E antibodies against allergens. Skin tests (prick or intradermal) detect immediate-type hypersensitivity via local mast cell degranulation. Both methods complement each other in allergy diagnosis but differ in sensitivity and specificity. A positive blood IgE does not always correlate with a positive skin test, and vice versa. Clinical relevance must be assessed together with symptoms and history. Skin tests carry a small risk of systemic reactions (anaphylaxis) and should only be performed under medical supervision. Evidence for the correlation between IgE and skin tests is moderate (human-moderate). No personalized DNA or biomarker interpretation is available from the given context.
