Allergies happen when the immune system overreacts, which is also called hypersensitivity. Most of the time, the immune system protects the body from viruses and bacteria. For people who have allergies, The immune system thinks that something like dust or pollen is dangerous, even though it is not. The immune system responds to what it thinks is a threat by making an allergic reaction. Some signs of an allergic reaction are sneezing, a runny nose, and a blocked nose.
The substance which causes allergy is called an allergen. A skin test is used to determine what allergens someone is allergic to. The test can tell you which substances (allergens) are causing your allergic reaction. Some of these things are pollen, dust, mould, and even medicines like penicillin.
