About the test
This test measures the IgE response to perennial rye grass, helping in the diagnosis of allergic diseases. It's a quantitative assay that should be used alongside other clinical information for a comprehensive diagnosis. Allergen-specific serum IgE testing, recognized by leading allergy and immunology academies, is often preferred due to certain conditions that may affect skin testing results or pose risks.
When is this test recommended?
This test may be recommended in situations where skin testing for allergies is not suitable, such as:
- Widespread skin disease
- Recent use of antihistamines or medications affecting skin test results
- Uncooperative patients
- High risk of severe allergic reaction from skin testing
Important Note:
A definitive allergy diagnosis should not rely solely on this test. A trained healthcare professional should consider all clinical and laboratory findings.
