What is the reference range for Egg White Specific IgE?

The standard reference range for Egg White Specific IgE is Class 0 (<0.35 kU/L) negative; increasing classes reflect rising antibody titre, not reaction severity.. Reference ranges vary by laboratory and assay platform — interpret in context of the issuing laboratory's stated range.

Which tests measure Egg White Specific IgE?

What does the Egg White Specific IgE test measure?

Q: What is Egg White Specific IgE?

Egg white carries the major allergens ovomucoid (Gal d 1), ovalbumin, ovotransferrin, and lysozyme. Ovomucoid is heat- and digestion-resistant and correlates with reactivity to cooked egg, while IgE confined to the heat-labile fractions often accompanies tolerance of baked egg. Egg white IgE in infancy is also an epidemiological marker of atopic trajectory.

Q: Why is Egg White Specific IgE measured?

Egg white sIgE is the usual first-line serological marker in suspected egg allergy. The titre offers a probabilistic, not deterministic, read on clinical reactivity, and the heat-stable component ovomucoid informs whether baked-egg introduction may be considered under specialist supervision rather than from the panel result alone.
