Is there a way to tell if a person has a food allergy?
assistant
Yes, it is possible to determine whether or not a person has a food allergy. A doctor can perform an allergy test by administering the suspected allergen and observing for any reactions such as skin rashes, difficulty breathing, nausea, vomiting, swelling of the face, tongue, or throat, or anaphylaxis. Additionally, a blood test may be used to measure specific antibodies in the body that indicate the presence of an allergic reaction.
