Allergen Profile, Ragweed-related
Use
Oral allergy syndrome (OAS), also known as pollen-food allergy syndrome, is a type of food allergy that causes localized reactions in the mouth and throat when certain fresh fruits and vegetables are consumed by affected individuals. People allergic to ragweed pollen often have allergies to watermelons, cantaloupes, honeydew melons, and bananas. OAS symptoms include itching of the lips, palate, tongue, and throat, which are confined to the mouth and throat region and usually resolve quickly. It is important to distinguish these symptoms from systemic and life-threatening allergic reactions that occur during anaphylaxis.
Special Instructions
The condition is typically self-limiting with symptoms occurring immediately upon contact with foods and resolving rapidly. This test includes an allergen profile for ragweed-related fruits such as banana, cantaloupe, honeydew melon, and watermelon, as well as common short ragweed.
Limitations
OAS primarily affects the mouth and throat and rarely affects other organs. It is important for patients to differentiate between OAS and systemic allergic reactions such as anaphylaxis. The test will not diagnose systemic allergic conditions and should not be used as a substitute for clinical evaluation by a healthcare provider.
