The ovomucoid (egg white) allergy test measures the level of specific IgE antibodies to a protein found in egg white. It is ordered to help evaluate a suspected egg allergy, especially when symptoms occur after eating eggs.
What it measures
- Ovomucoid-specific IgE — The main marker; indicates sensitization to this egg white protein.
- Total IgE — Sometimes measured to provide context, though not specific for egg allergy.
- Other egg white proteins (e.g., ovalbumin, ovotransferrin) — May be tested together to give a fuller picture of egg white allergy.
Who it is for
This test is typically ordered by allergists, immunologists, or primary care clinicians when a patient has a history of reactions after eating eggs or egg-containing foods.
Preparation
No fasting or special preparation is required. The blood sample can be drawn at any time of day.
Results and what they mean
Results are reported as a numerical level of specific IgE, often with a reference range. A clinician interprets these results alongside your symptoms and medical history; a positive test alone does not confirm an allergy. This is general information, not medical advice.
