Yes. Food allergy is not diagnosed by food skin testing. Food allergy is initially diagnosed by taking a history and if that history is c/w food allergy reaction then skin testing and /or blood testing is performed to confirm. Testing for food allergy in the absence of a relevant history will result in 40 -60% false positive results.
No. Your doctor can order blood work for food allergy testing.
Whats more common mild food allergies or anaphylaxis reaction to foods?! never had allergies to food and blood test was neg but doc says specialist?!
Mouth tingling? To have a food allergy you have to have a reaction (hives, wheeze, swelling...) and an elevated blood test. Are you experiencing mouth/throat symptoms with certain foods? Oral allergy syndrome is when you have a cross reaction to a protein from seasonal allergen that the body confuses for a food. Common triggers are apples and peaches. Best to avoid these foods or boil them to prevent symptoms.
