Egg Yolk
Use
The Egg Yolk test, also known as F075-IgE Egg (Yolk), measures specific IgE antibodies to egg yolk allergens using ImmunoCAP® technology. It assists in diagnosing individuals with suspected egg yolk allergies, helping to identify allergic sensitivity and aiding in allergy management. Quantifying egg yolk-specific IgE levels can inform the initiation or avoidance of dietary changes involving egg-containing products. Healthcare providers use the IgE concentration to evaluate clinical allergic response risk and severity by correlating IgE levels with historical exposure data and patient-reported symptoms.

Limitations
The Egg Yolk IgE test assesses IgE antibodies related to egg yolk allergens but does not evaluate other components of egg proteins such as egg white proteins. Results should be interpreted within the context of known clinical history and potential cross-reactivity with other allergens. Allergen-specific IgE tests do not measure food tolerance, and patients with low IgE levels may still exhibit severe allergic reactions. Analytical variability may occur with insufficient serum volume or inappropriate specimen handling, affecting precise measurement and interpretation.
