Definition:
A "delayed allergy" is a type of allergic reaction that does not happen immediately after you come into contact with something that you are allergic to. Instead, the symptoms appear several hours or even days later.
When to use: You can use "delayed allergy" when talking about a situation where someone has an allergic reaction that takes time to show up after exposure to an allergen (something that causes an allergy).
Context: This term is often used in medical contexts, especially when discussing food allergies, medications, or environmental allergens.
In more advanced contexts, you might encounter discussions about the mechanisms behind delayed allergies, including how the immune system reacts over time.

Delayed hypersensitivity: A more technical term often used in medical contexts.
Late-onset allergy: Another way to describe allergies that appear after a delay.
