Allergen, Insects and Venom, White-Faced Hornet
Also known as: HORNET WF
Use
This test quantifies the level of allergen-specific IgE for the white-faced hornet, which helps in diagnosing allergens related to insects and venom. The presence of allergen-specific IgE is indicative of sensitization and potential allergic reaction when exposed to the specific allergen. However, the concentration measured may not directly correlate with clinical response or skin testing results, underscoring the importance of correlating laboratory findings with clinical history and observed reactions.
Special Instructions
Multiple patient encounters should be avoided during the test preparation to ensure accurate results. It's crucial to follow specific specimen collection and handling instructions, especially when ordering multiple allergens. This ensures adequate serum volume for testing.
Limitations
Allergen-specific IgE concentrations may not always correlate with the degree of clinical allergy or the results from skin tests. A negative result does not exclude the possibility of an allergic reaction or anaphylaxis. Clinical correlation with history and observed reactions is essential. Additionally, allergen results between 0.10 and 0.34 kU/L have undetermined clinical relevance and should be interpreted by specialists.
