Egg Component Panel
Clinical Use
Order TestUse
The Egg Component Panel is a follow‑on test performed when elevated Egg White IgE is detected (≥0.10 kU/L). It measures specific component IgE antibodies—namely ovalbumin IgE and ovomucoid IgE—to provide more detailed allergen characterization for egg white, aiding clinicians in refining diagnosis of egg allergen sensitivities.
Special Instructions
This test is not orderable on its own; it is reflexively triggered when Egg White IgE is ≥0.10 kU/L. The specimen is forwarded to Quest Diagnostics for component testing after initial screening.
Limitations
