Description
House dust mites are one of the most common causes of bronchial asthma, allergic rhinitis and conjunctivitis, and atopic dermatitis. They can be found in mattresses, carpets, etc.; feed on dead skin particles that a person loses daily.
Mite allergens enter the body by inhalation, with an increased concentration of dust in the air or by contact with products that may contain an allergen (clothes, pillows, blankets, etc.).
The waste products of mites are digestive enzymes: Derf1 and Derp1 proteins, which contribute to the destruction of human skin cells. The following allergy symptoms are caused: redness (hyperemia), skin rashes, itching, swelling of the skin, redness and burning of the mucous membrane of the eyes, lacrimation, swelling of the eyelids, sneezing, coughing, shortness of breath, bronchospasm.
The purpose of this test is to determine an allergic reaction to the house dust mite Dermatophagoides pteronyssinus. The performance of this test is safe for the patient compared to skin tests (in vivo), as it excludes contact with the allergen.

- with a continuously relapsing course of respiratory diseases without periods of remission;
- with a polyvalent nature of sensitization, when it is not possible to conduct in vivo testing with suspected allergens, or with a false positive result of skin testing.
Recommended to assess the risk of developing allergic reactions to the house dust mite Dermatophagoides pteronyssinus in children in cases where parents suffer from allergic diseases, including those manifested by contact with house dust.
