Hymenoptera Venom Allergy (HVA) With Components Profile, II
Use
This test supports the diagnosis of hymenoptera venom allergy (HVA) by detection of sIgE antibodies to whole venom extracts and individual allergenic venom proteins. Identifying sIgE responses to specific molecular targets with component resolved diagnostics (CRD) helps fine-tune the diagnosis by distinguishing species-specific, co-reactive, or cross-reactive sensitizations. An accurate diagnosis, in turn, facilitates treatment, including prescription of venom immunotherapy.1
Special Instructions
If reflex testing is performed, additional charges/CPT code(s) may apply.
Limitations
The high rate of asymptomatic sensitization to hymenoptera venom makes an accurate diagnosis of Hymenoptera venom allergy challenging. There is no correlation between the severity of sting reactions and the concentration of venom sIgE to whole venom extracts or individual components, and some patients with minimal level or absent specific IgE to these entities can develop severe anaphylaxis.
