Cow's milk allergy is one of the most common childhood food allergies. Specific IgE antibodies to milk identify sensitization, though clinical allergy must be confirmed by history or supervised challenge. Milk allergy typically resolves in most children by school age.
This test is used in children with reactions after milk ingestion, eczema, gastrointestinal symptoms, or anaphylaxis. Results guide avoidance and inform timing of supervised reintroduction. Sample type is serum.
