Allergic rhinitis, also known as allergic rhinitis, is an allergic disease of the nasal mucosa and can cause a variety of complications. Allergic rhinitis has four main characteristics: itchy nose, sneezing, runny nose and nasal congestion. Allergen testing, say goodbye to allergic rhinitis The current clinical treatment of allergic rhinitis is usually only to relieve the symptoms, but not to find the real cause of allergy, and therefore can not do targeted prevention and treatment, resulting in repeated aggravation of the disease, and persistent treatment. Therefore, it is recommended that patients with frequent allergies must undergo allergen screening tests to find out whether contact, ingestion or inhalation allergens are causing the allergic reaction in order to solve the problem at its root. Never treat allergies as a minor problem and ignore the examination and treatment, which eventually leads to serious consequences. The current clinical treatment of allergic rhinitis is usually only to relieve the symptoms (commonly known as symptomatic treatment), but not to find the real cause of allergies (that is, the treatment of the cause), and therefore can not do targeted prevention and treatment, resulting in repeated aggravation of the disease, and delayed. For patients with allergic rhinitis, it is important to do allergen screening tests to find out whether the allergic reaction is caused by contact, ingested or inhaled allergens in order to solve the problem at the root. The purpose of allergen testing is to provide more effective desensitization therapy. The term “desensitization therapy” is also known as “hyposensitization therapy” and is now standardized in the medical community as “immunotherapy”. The most common method of desensitization is subcutaneous injection, but other routes of administration are now available, such as oral, intranasal, sublingual, etc. Desensitization is the application of a low concentration of an allergen to an allergic patient, followed by a gradual increase in the concentration, so that the allergic patient gradually adapts to the stimulation of the specific allergen and eventually no longer has an allergic reaction when exposed to the corresponding allergen in daily life.
