Allergies occur when a person's immune system has adverse reactions to normally harmless substances (dust, fish, nuts or pollen) in the vicinity. Allergens are the cause of an allergic reaction that is usually fast.
Allergies are classified into types of hypersensitivity and are officially referred to as type I (immediate) hypersensitivity.
An expert in immunology/allergy can diagnose, treat, and manage your allergies and will create a treatment plan that is right for you. You can find more about allergy skin test through various online sources.
You should go for allergy testing to determine the allergens you are sensitive to. This test can be performed using blood serum or on the skin directly.
The skin test is the most common and involves that the potential allergen is placed on the surface of the skin where the doctor will observe the reaction. If you receive a positive reaction from one of your tests, it can narrow down what is causing your allergic reactions.

Allergy tests were also performed on people who have skin rashes, eczema, or asthma that is difficult to manage to determine if allergies are responsible for the damage or even cause the condition.
