The ovalbumin (egg white) allergy test is a blood test that checks for antibodies your immune system may make against a protein in egg white called ovalbumin. It is usually ordered when a person has had symptoms after eating eggs, or when a clinician wants to confirm or rule out an egg allergy.
What it measures
- Ovalbumin-specific IgE — The main marker; IgE is an antibody linked to allergic reactions.
- Total IgE — Sometimes measured to give context, though it does not diagnose egg allergy by itself.
- Egg white-specific IgE — May be measured alongside ovalbumin to compare reactions to different egg proteins.
- Other egg protein-specific IgE — Markers such as ovomucoid may be checked to see which egg proteins trigger a reaction.
Who it is for
A clinician such as an allergist, pediatrician, or primary care provider typically orders this test. It is common in children and adults who have had possible allergic symptoms after eating eggs.
Preparation
No fasting or special preparation is usually required. Tell your clinician about any medications you take, since some medicines can affect test results.
Results and what they mean
Results are reported as a level of specific IgE, often with a reference range or class score. A higher level may suggest sensitivity, but it does not confirm an allergy on its own. A clinician interprets the result with your symptoms and history. This is general information, not medical advice.

Frequently asked questions
Does a positive result mean I am allergic to eggs?
Not always. A positive result shows your immune system may react to ovalbumin, but only a clinician can decide if you have a true allergy based on symptoms and history.
Can I eat eggs before this test?
Yes. Eating eggs before the test is not usually a problem, and fasting is not required.
How long does it take to get results?
Results are typically available in 1 to 3 business days.
Will this test tell me if I can eat baked eggs?
It may help, but baked egg tolerance is often judged by a clinician using your history and sometimes a supervised food challenge.
