Skin testing initially may be performed, followed by controlled ingestion of increasing amounts of the suspected substance while under careful observation. Ingestion challenges can be performed with one food item at a time-- a good example would be almonds. Ingestion challenges may also be done with antibiotics if this is the item in question. These challenges may be very helpful in expanding the diet of someone with multiple food allergies, or expanding the drug options of someone with multiple drug allergies. |
