Hornet, White Face
Also known as: Venom
Use
The Hornet, White Face test measures the presence of specific IgE antibodies to the white-faced hornet venom using the Thermo Fisher ImmunoCAP® methodology. This test helps to determine a patient's allergenic sensitivity to the venom of the white-faced hornet, which can assist in diagnosing insect sting allergies and help in the management and treatment of allergic reactions, including anaphylaxis.
Special Instructions
The test utilizes a red-top tube or gel-barrier tube for specimen collection, requiring a serum volume of 0.2 mL. Stability conditions for the sample include room temperature for 14 days, refrigerated for 14 days, and frozen for up to 3 months with stable freeze/thaw cycles up to three times. Ensure proper storage conditions to maintain sample integrity.
Limitations
This test specifically measures IgE antibodies against the white-faced hornet venom and does not assess other possible venom allergies or provide a comprehensive allergy profile. False negatives may occur if the venom-specific antibodies are below the detection threshold. The results should be considered in conjunction with clinical evaluations and patient history. Cross-reactivity with other Hymenoptera venoms or non-venom allergies may also affect results.
