Allergen, Food, Whole Egg, IgG
Also known as: WHOLE EGG
Use
This test is used for the quantitative detection of whole egg IgG antibodies in serum, measured using a Quantitative ImmunoCAP Fluorescent Enzyme Immunoassay. It is intended to help diagnose and monitor patients with potential egg allergies or sensitivities. Levels less than 2.00 mcg/mL represent absent or undetectable levels of allergen-specific IgG antibody, which may be used by clinicians in assessing patient exposure or immune response to whole egg allergens.
Special Instructions
This test is not New York state approved. Do not submit samples to ARUP if they are intended for New York state. Ensure specimen separation from cells is performed ASAP or within 2 hours of collection.
Limitations
The test is developed for clinical purposes and is performed in a CLIA certified laboratory, but it has not been cleared or approved by the US Food and Drug Administration (FDA). The test may not cover all allergens or represent clinical symptoms, and varying IgG levels may not correlate directly with allergic symptoms.
