Purpose of upper gi in allergy identification

Patient

Q: Does it make sense to do an upper gi looking for EoE when a confirmed allergen (removed from diet, then re-introduced) is still in the system or should the procedure be done after the known allergen has completely cleared the system so that any remaining allergens are more likely to be identified?
