Allergies, also called hypersensitivity reactions, are responses of the immune system (the defenses of our body) to come into contact with substances called allergens which are usually tolerated by most people. These are frequent pathologies that affect more than 25% of the world’s population according to the World Health Organization (WHO). In addition, over the last several decades, changes in the environment, habitat and way of life and a greater number of pets have favored the progression of allergy. Immunotherapy, also known as hyposensitizing therapy, reduces the sensitization of patients by attenuating the symptoms they experience in contact with the allergen. Immunotherapy is usually effective, the improvement is observed a few months after having started the vaccination, becoming apparent around the first year of treatment.

Diagnosis of allergy

A skin test or prick test can be used to diagnose allergy. The prick-test is a set of sterile allergen extracts prepared for the diagnosis of allergenic hypersensitivity by prick test.
