Dust mite Dermatophagoides pteronyssinus (d1)0063
Dermatophagoides pteronyssinus – a house dust mite, one of the most active allergenic components of house dust. It lives in beds and bedding, feeding on epidermal flakes. It is found on the skin, in urine, sputum, and lungs. It causes allergic reactions mainly through sensitization to mites and their metabolites.
The determination is carried out by the FEIA (Fluorescence Enzyme Immunoassay) method – quantitative determination of specific IgE antibodies.
- Diagnosis of allergic reactions.
- Assessment of sensitization level and risk of allergy development.
- Monitoring the effectiveness of therapy.
- Assessment of sensitization level after allergen avoidance.
- Evaluation of immune system status.
- Blood should be drawn in the morning on an empty stomach or 4 hours after eating.
- Drinking plain still water is allowed.
- Do not smoke for 30 minutes before the test.
- Children under 1 year should not eat 30-40 minutes before the test; children aged 1-5 years should fast for 2-3 hours.
Dermatophagoides pteronyssinus is a major house dust allergen causing allergic rhinitis, asthma, atopic dermatitis, and other allergic diseases. Sensitization to this mite is a common cause of respiratory allergies, which can be complicated by asthma exacerbations, especially in children. Exposure to mite allergens promotes inflammation of the upper and lower respiratory tracts, causing symptoms of allergic rhinitis and asthma. The test helps determine risk, monitor therapy, and conduct specific allergen immunotherapy to reduce symptoms.
