Herb Allergens Panel
The Grass Pollen Allergen Panel (11) is a serological allergy test designed for the initial assessment of IgE-mediated sensitization to the major grass pollen allergens. Grasses are among the most common causes of seasonal allergies and release large amounts of pollen during their flowering season, triggering respiratory symptoms in sensitized individuals.
The test determines the presence of specific IgE antibodies to individual allergens and serves as a valuable tool in the evaluation of patients with symptoms suggestive of seasonal allergic rhinitis, allergic conjunctivitis, or allergic asthma. The results contribute to guiding further allergy investigations and establishing the appropriate diagnostic approach based on the patient's clinical manifestations and medical history.
Included allergens
| Code | Allergen | Description |
|---|---|---|
| g2 | Bermuda grass / Couch grass (Cynodon dactylon) | Grass pollen |
| g3 | Cock's-foot grass / Orchard grass (Dactylis glomerata) | Grass pollen |
| g5 | Ryegrass / Perennial ryegrass (Lolium perenne) | Grass pollen |
| g6 | Timothy grass (Phleum pratense) | Grass pollen |
| g8 | Meadow grass / Kentucky bluegrass (Poa pratensis) | Grass pollen |
| g10 | Johnson grass (Sorghum halepense) | Grass pollen |
| g12 | Rye (Secale cereale) | Grass pollen |
| g13 | Velvet grass / Yorkshire fog (Holcus lanatus) | Grass pollen |
| g14 | Cultivated oat (Avena sativa) | Grass pollen |
| g15 | Common wheat (Triticum aestivum) | Grass pollen |
| g16 | Meadow foxtail / Foxtail grass (Alopecurus pratensis) | Grass pollen |
Indications
- recurrent sneezing, nasal congestion, runny nose or nasal itching during the pollen season;
- eye itching, excessive tearing or symptoms suggestive of allergic conjunctivitis;
- cough, wheezing or symptoms suggestive of allergic asthma that appear or worsen during the warm season;
- respiratory symptoms occurring after exposure to grass or during outdoor activities;
- suspected seasonal allergic rhinitis (hay fever);
- initial assessment of patients with suspected sensitization to grass pollen.
Procedure
The analysis is performed using a venous blood sample collected from the elbow crease. The procedure takes only a few minutes and is carried out by qualified medical personnel.
Test method
Determination of specific IgE antibodies in serum against individual allergens using an automated immunological method.
Interpretation of results
The test result allows the assessment of sensitization to the grass pollen allergens included in this panel.
In the case of a positive result, an allergist may recommend additional investigations, including the determination of specific IgE antibodies to individual allergens or molecular allergy diagnostics, depending on the patient's clinical presentation and medical history.
The results should be interpreted in conjunction with the patient's symptoms, the timing of symptom onset, and other relevant clinical findings.
Preparation:
No special preparation is required before sample collection.
The test can be performed at any time and does not require discontinuation of antihistamine treatment, as these medications do not affect the determination of specific IgE antibodies in the blood.
Patients are advised to inform the medical staff about any ongoing treatments and known allergic reactions to ensure accurate interpretation of the results.
