Allergen, Food, Egg Yolk
Also known as: EGG YOLK
Use
This test is used to measure IgE antibodies specific to egg yolk allergens in the patient's serum. Such measurement is vital to diagnose egg yolk-related allergies and assess the likelihood of an allergic reaction. The test aids as part of an allergy evaluation and should be considered alongside clinical history and other diagnostic tests like skin testing. Allergy laboratory results should correlate with clinical history and in vivo reactivity to specific allergens.
Special Instructions
Not provided.
Limitations
While the test provides quantitative results for egg yolk-specific IgE, these concentrations may not directly correlate with the degree of clinical response or skin test results. There could be instances where a negative result does not completely rule out clinical allergy or the risk of anaphylaxis. Results that fall into the range of 0.10-0.34 kU/L may not have clinical relevance determined and are intended for specialist use, necessitating careful consideration alongside clinical findings and history.
