Allergen, Grass, Bermuda
Also known as: BERMUDA
Use
This test measures the amount of Immunoglobulin E (IgE) antibodies specific to Bermuda grass (Cynodon dactylon) in the patient's serum. Elevated levels of allergen-specific IgE indicate sensitization to this allergen, which may result in allergic reactions such as rhinitis, conjunctivitis, asthma, or other allergic responses upon exposure. The correlation of allergy laboratory results with clinical history and in vivo reactivity to specific allergens is essential to determine the clinical relevance of the results.
Special Instructions
For accurate results, it is advised to separate the serum from cells as soon as possible, ideally within 2 hours of collection. The test employs the Quantitative ImmunoCAP Fluorescent Enzyme Immunoassay method.
Limitations
Allergen results in the range of 0.10-0.34 kU/L are intended for specialist use, as the clinical relevance is undetermined. The increasing concentration of allergen-specific IgE does not necessarily correlate with the severity of clinical symptoms or skin test results. Additionally, a negative result does not exclude the possibility of clinical allergy or anaphylaxis. Proper correlation with the patient’s clinical history and in vivo tests is needed for accurate diagnosis.
