New ImmunoCAP Bee Venom Components

Last updated: 15th May, 2020

Discover the new ImmunoCAP bee venom components

  • Patients with primary bee sensitization may test negative for Api m 1 but positive for other bee venom components.
  • Api m 10 can be absent or/underrepresented in VIT extracts – VIT of patients sensitized to this component may be less efficient.
  • Adding venom components rApi m 2, rApi m 5 and rApi m 10 to your test panel improves diagnostic specificity and supports more well-founded decisions for VIT.
  • Successful venom immunotherapy (VIT) is more likely when treatment selection is based on genuine sensitization to bee and/or wasp venom.

ImmunoCAP Allergen Components help you resolve double positivity

Distinguish between true co-sensitization to bee and wasp, and CCD-dependent cross reactivity

  • Honey bee: rApi m 1, rApi m 2, rApi m 5 and rApi m 10
  • Common/paper wasp: rVes v 1, rVes v 5, rPol d 5

Help match venom immunotherapy to the patient’s sensitization profile

A broad toolbox of ImmunoCAP  allergen components

Over 100 allergen components that can help you:

  • Assess risk of systemic reactions in patients with food allergy
  • Explain symptoms due to cross-reactivity
  • Identify the appropriate immunotherapy for the individual patient
