Yes: Patch testing can detect certain types of food allergies. For anaphylactic type (ige mediuated) food allergies, standard skin prick testing or specific ige blood tests are better at identifying food allergies. For other non-ige mediated reactions such as eosinophilic esophagitis, patch testing can identify some additional food sensitivities. Only have test recommended by a trained md.

No: Food allergy is a very precisely defined reaction - allergy antibody medicated reaction to a food that causes an immediate reaction that can be itchy, hives, swelling, SOB, wheezing, abdominal pain, nausea, vomiting, diarrhea and in severe cases death. There are those who are offer "patch testing" to define "food allergy or sensitivities" - these are not valid test and should be avoided.
