  2. Documentation of milk-specific serum IgE >15 kUᴀ/L or > 5 kUᴀ/L if younger than 1 year;
  3. Documented cow's milk skin prick test wheal >10mm;
  4. Physician-supervised oral food challenge that elicited immediate, objective, allergic symptoms.

• Participant's parent(s) agree for their child to stop oral steroid use within 14

  days and antihistamine use within 7 days prior to confirmation of diagnosis and food challenges.
