Specific IgG W9 — Weed Grass Mix (Ragweed, Wormwood, Plantain, Goosefoot, Orache, Nettle)
The study of specific immunoglobulin G class antibodies to weed grass pollen allergens is conducted to assess the body's immune response with prolonged or repeated allergen contact. The test is used as part of comprehensive allergological diagnostics, in chronic allergic diseases, and for monitoring allergen-specific immunotherapy efficacy.
Test composition:
- Determination of specific IgG class immunoglobulins in blood serum
- IgG antibodies to weed grass pollen allergens included in allergen mix W9 are tested
- The mix includes pollen allergens of ragweed, wormwood, plantain, goosefoot, orache, and nettle
- The test aims to detect sensitization fact and degree of the body's immune response to the specified allergens
- The study is performed by enzyme immunoassay or immunochemiluminescence method, with high sensitivity and specificity
- The result reflects specific IgG concentration and is used for immunological assessment of the body's reaction to pollen allergens
Clinical significance:
- Determination of specific IgG allows assessment of immune response character on contact with weed grass allergens
- The test is used for monitoring patients with chronic allergic diseases
- Results are used for assessing and monitoring allergen-specific immunotherapy efficacy
- 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 allergic symptoms related to weed grass flowering
- Allergic rhinitis, conjunctivitis, bronchial asthma
- Suspected pollinosis
- Prolonged or repeated contact with pollen allergens
- Need for dynamic monitoring of allergic diseases
An elevated specific IgG level indicates the presence of an immune response to W9 mix weed grass pollen
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
