Allergenicity

Allergenicity refers to the potential of a substance to cause an allergic immune response in certain individuals. When someone with a sensitivity encounters an allergen—such as certain foods, pollens, or chemicals—their immune system mistakenly identifies it as harmful, triggering reactions like sneezing, hives, or even more severe symptoms. Not everyone reacts to the same substances; allergenicity varies based on genetics and exposure. Understanding allergenicity helps in identifying and managing allergies, ensuring safety, especially in food, pharmaceuticals, and other products.
