Allergy testing or Skin Prick
A skin prick or allergy happens when the immune system of the human body has an uncommon response to an infective substance. The activity of the immune system is to discover outside substances, for example, infections and microscopic organisms, and dispose of them. Ordinarily, this reaction shields us from risky infections.
Individuals who have hypersensitivities skin also have an over-delicate immune system. They can create skin rashes and different conditions because of dust, latex, drugs or different things. The substances that cause allergy are called allergens. Skin allergies are also called allergic contact dermatitis. It occurs when your skin comes in contact with an infected person.
