Allergen, Food, Egg Whole
Also known as: EGGWHOLE
Use
The Allergen, Food, Egg Whole test measures the concentration of allergen-specific IgE antibodies to egg whole, which can help diagnose egg allergies. The test provides quantitative measurements of IgE levels, which can be used to assess the likelihood of an IgE-mediated allergic reaction to egg. The results need to be correlated with clinical history and other allergy testing methods as the concentration of IgE may not directly correlate with the severity of clinical reactions.
Special Instructions
Not provided.
Limitations
While the test results indicate the presence and levels of specific IgE antibodies, these may not correspond directly to clinical symptoms or skin test results when exposed to the allergen. The correlation of test results with clinical history and in vivo reactivity is essential. A negative result does not rule out clinical allergy or the possibility of anaphylaxis. The clinical relevance of results in the 0.10-0.34 kU/L range is undetermined and intended for specialist interpretation.
