Allergen, Grass, Bahia
Also known as: BAHIA
Use
The Allergen, Grass, Bahia test is designed to measure the concentration of specific Immunoglobulin E (IgE) antibodies to Bahia grass pollen in the serum. It helps in the diagnosis and management of allergic diseases such as allergic rhinitis and asthma associated with grass pollen. Detection of Bahia grass-specific IgE can assist in identifying potential allergen triggers, guide management strategies, and evaluate response to therapy.
Special Instructions
For patients undergoing multiple allergen tests, refer to the 'Allergen Specimen Collection Instructions' at www.aruplab.com/testing/resources/specimen. Ensure careful coordination to avoid multiple patient encounters and follow specific guidelines for serum collection and preparation.
Limitations
The test is limited by its inability to correlate quantified levels of allergen-specific IgE with the severity of clinical allergies or predict reactions to skin testing accurately. A negative result does not entirely rule out an allergy to Bahia grass. Results in the range of 0.10-0.34 kU/L are inconclusive and meant for use by specialists, as their clinical relevance remains undefined. It is crucial to integrate test results with clinical history and in-vivo reactivity to obtain an accurate diagnosis.
