Patch Test Method: Placement of a patch that contains several different food allergens on the patients back or forearm that is left in place for 48-72 hours. The patient will return to the clinic to have the patch removed and the results interpreted.
Prick Method: The skin is pricked with a blunt needle that has been immersed with a variety of food allergen extract.
On a case by case basis, our board-certified allergist will determine if lab work is a more suitable testing option to identify food allergies.
There are currently no FDA approved treatments available for food allergies, although some clinics do offer sublingual immunotherapy treatment.
Patients with severe reactions to foods should always carry injectable epinephrine to be given in emergency situations. Epinephrine is an emergency medication that requires emergent care even after administration of the medication. You should have someone drive you to the nearest hospital.
Elimination diet is the best treatment option for those that suffer from food allergies. Elimination diet consists of eliminating the foods that the patient tested positive to and slowly reintroducing them after 6 weeks to determine if the food is truly an allergy or just a false/positive test result. The key to the elimination diet is a food and symptom journal, where the patient will write down how much they have eaten of a certain food and any symptoms that occurred. It is very important to record every food, amount, time of ingestion, as well as time that any symptoms occurred. This will help to notify you of any delayed food reaction and identify other food allergies not discovered during allergy testing.
Our board-certified allergist/immunologist will decide based on food allergy testing and/or patch testing results if collaborative care is warranted with a nutritional counselor and a gastrointestinal doctor for those with multiple and severe food allergies.
