Pineapple is known to contain proteins that can trigger allergic reactions in susceptible individuals. The Pineapple Antigen is extracted and purified from pineapple proteins and is used to identify individuals who are allergic to pineapple. It is commonly used in skin prick tests or blood tests to determine allergic responses. By measuring specific antibodies in the blood or conducting skin prick tests, healthcare professionals can accurately diagnose pineapple allergies and provide appropriate management and treatment plans.
