ImmunoCAP Allergy Testing Solutions

Virant Diagnostics pioneers the next-generation of precision diagnostics in the field of allergology with the incorporation of ImmunoCAP.

About Our Allergy Laboratory

Using the ImmunoCAP tests and Phadia instrument from ThermoFisher Scientific, our laboratory is able to offer comprehensive allergy testing with accurate and precise results. We determine levels of specific IgE (sIgE) and IgG4 for whole allergens and their components via fluorescent enzyme immunoassay (FEIA). Our test menu covers the broad spectrum of whole allergens, including foods, pollens, animal dander, insect venoms, and occupational allergens. We test over 550 whole allergens and 100 components. Customized tests and panels tailored to specific patient needs are available upon request.

Specimen Requirements:


  1. For each panel ordered, completely fill one red-top tube or gel barrier tube with whole blood 
  2. Separate serum by centrifugation
  3. Transfer the serum into a plastic transport tube


  • Within 7 days: store between 2-7ºC (36-44ºF)
  • Beyond 7 days: -20ºC (-4ºF)
  • Avoid repeated thawing and refreezing
