House Dust Mite (Dermatophagoides pteronyssinus)
The study of specific immunoglobulin E class antibodies to house dust mites is conducted to assess the body's allergic sensitization on contact with household allergens. The test is used as part of comprehensive allergological diagnostics, in chronic allergic diseases, and for monitoring allergic reactions.
Test composition:
- Determination of specific IgE class immunoglobulins in blood serum
- IgE antibodies to house dust mite (Dermatophagoides pteronyssinus) are tested
- The test aims to detect sensitization fact and degree of the body's allergic response to this allergen
- The study is performed by enzyme immunoassay or immunochemiluminescence method, with high sensitivity and specificity
- The result reflects specific IgE concentration and is used for immunological assessment of the body's reaction to household allergens
Clinical significance:
- Determination of specific IgE allows assessment of the allergic reaction character on contact with house dust mites
- The test is used for monitoring patients with chronic allergic diseases
- Results are used for assessing allergy development risk and planning preventive or therapeutic measures
- The study complements clinical data and other laboratory test results
Biomaterial: Venous blood
- Blood is submitted fasting
- It is recommended to avoid alcohol the day before the test
- Before blood collection, it is advisable to avoid intense physical exertion and stressful situations
- The attending physician should be informed about taking hormonal medications, immunomodulators, and antihistamines.
- Seasonal or year-round allergic symptoms related to house dust contact
- Allergic rhinitis, conjunctivitis, bronchial asthma
- Suspected allergy to house dust mites
- Need for dynamic monitoring of allergic diseases
An elevated specific IgE level indicates the presence of allergic sensitization to house dust mite (Dermatophagoides pteronyssinus)
A low level may indicate absence of significant sensitization or formation of immunological tolerance
Final interpretation is performed by a physician considering the clinical picture and other test data
Which doctor to consult:
Allergist — for diagnosing allergic diseases, identifying causes of sensitization, interpreting test results, and selecting individual treatment tactics or allergen-specific immunotherapy
Immunologist — for assessing immune system status, analyzing immune response to allergens, and correcting immunological disorders if needed
General practitioner — for initial assessment of the patient's general condition, prescribing examinations, and referral to specialists
