Use

The Allergen, Grass, Meadow Fescue test is used to determine the presence of specific IgE antibodies to the Meadow Fescue grass allergen. IgE antibodies are involved in allergic reactions, and their presence in significant amounts can indicate an allergic sensitivity. This test is suitable for evaluating individuals who may have allergic rhinitis, asthma, or other allergic conditions potentially triggered by exposure to this specific grass pollen. The correlation of laboratory findings with clinical history and other allergy testing is crucial for accurate diagnosis.

Special Instructions

The test requires careful handling of specimens to avoid degradation. Serum must be separated from cells within two hours of collection to maintain sample integrity. Please refer to 'Allergen Specimen Collection Instructions' for multiple allergen orders to ensure proper specimen management.

Limitations

While the test measures the concentration of allergen-specific IgE, these concentrations may not correlate directly with the severity of clinical symptoms or skin test results when exposed to the allergen. A normal result does not necessarily rule out clinical allergy or anaphylaxis, and low levels of IgE may not reflect all instances of allergic response. The interpretive guidelines indicate that IgE levels from 0.10-0.34 kU/L have undetermined clinical relevance and should be interpreted by a specialist in the context of the patient’s history and other studies.
