Increase confidence in allergy results
The 3gAllergy—Allergen-specific IgE assay uses third-generation chemiluminescent technology and proprietary liquid allergens that preserve their native conformational structure, maximizing binding and resulting in standardized, quantifiable results for informed decision making.
3gAllergy—Allergen-specific IgE assay sequence
Serum and liquid-specific allergens incubate with anti-ligand-coated polystyrene bead.
Ligand-labeled liquid allergens bind to serum IgE antibodies and to the anti-ligand-coated bead.
Alkaline phosphatase-conjugated monoclonal anti-IgE is added and binds to serum IgE.
A chemiluminescent substrate is added, and light is emitted to provide a quantitative IgE result.
3gAllergy Allergen-specific IgE assay components
- Specific allergens and mixed allergen panels: When an allergic patient is tested, a reactive result may indicate a response to a specific allergen or a mix of allergens. Specific allergens and mixed allergen panels require the Universal Kit.
- Universal Kit: All specific allergens and mixed allergen panels run with the Universal Kit to provide a result from the patient sample. One master curve applies to all specific allergens and mixed allergen panels.
Improve operational efficiency
Improve productivity with a patented, high-capacity allergen wedge
Each allergen wedge can be customized with up to six user-defined, bar-coded allergen vials. As many as 23 wedges plus a universal reagent wedge fit on each carousel, for a total capacity of up to 138 allergens onboard at any time.
Minimize waste and eliminate errors
Reagent onboard stability of 90 days minimizes waste. Bar-coded allergens eliminate errors. All allergen information is scanned from the wedge.
Run allergy testing alongside your routine and specialty immunoassays
Consolidating multiple tests on a single, easy-to-use, and compact analyzer—including allergy and a wide range of specialty offerings—the IMMULITE 2000 XPi Immunoassay System makes it simple to scale your capabilities without disrupting regular, day-to-day operations.
