The study of specific immunoglobulin E class antibodies to weed plant and agricultural crop allergens is conducted to assess the body's allergic sensitization on contact with pollen and plant particles. This test allows determination of how the body reacts to various plant allergens, detects the presence of allergy, and assesses the risk of seasonal and year-round allergic reaction development.
The test is especially important for patients with seasonal allergy symptoms — such as runny nose, sneezing, eye itching, cough, or bronchial asthma exacerbation — occurring during weed plant flowering or on contact with agricultural crops. Test results help the physician precisely determine which plants cause the allergic reaction and select effective prevention and treatment.
The study is used as part of comprehensive allergological diagnostics, as well as for monitoring the dynamics of the body's allergic response with prolonged allergen contact. It may be useful for planning allergen-specific immunotherapy and assessing its efficacy.
Test composition
The test is performed based on venous blood, in which the concentration of specific IgE class immunoglobulins to pollen and plant particles is determined.
The panel includes annual wormwood, bitter wormwood, sunflower, and hemp allergens.
Study method — enzyme-linked immunosorbent assay (ELISA) or immunochemiluminescence assay (ImmunoCAP), with high sensitivity and specificity.
The test result reflects the specific IgE level, allowing determination of the degree of body sensitization to each plant allergen.
Clinical significance
Determination of specific IgE to weed plants and agricultural crops helps the physician assess the character of the body's immune response on pollen or plant particle contact, identify specific allergens causing seasonal or chronic allergic reactions, plan individual prevention measures including allergen contact limitation, monitor allergen-specific immunotherapy efficacy, and supplement the clinical picture and other laboratory test results for precise diagnosis of allergic diseases.
The test is especially useful for patients with seasonal allergic rhinitis and conjunctivitis, bronchial asthma exacerbating during weed plant flowering periods, suspected pollinosis, and the need for dynamic monitoring of the body's allergic status.
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.
Prescribed for:
- Appearance of seasonal or year-round allergic symptoms related to contact with weed plants and agricultural crops.
- Recurring sneezing, runny nose, nasal congestion, or tearing.
- Bronchial asthma exacerbation during plant flowering period.
- Suspected pollinosis and need to clarify the specific allergen.
- Planning allergen-specific immunotherapy.
- Need to monitor the dynamics of the patient's allergic status.
An elevated specific IgE level indicates sensitization of the body to pollen and plant particles of specific weed plants and agricultural crops, indicating a potential allergic reaction on contact with them.
A low specific IgE level may mean absence of significant sensitization or formation of immunological tolerance to allergens.
Final interpretation is performed by a physician considering the clinical picture, medical history, and other laboratory tests.
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
