Quick answer
An egg yolk allergy test is a blood test that detects immunoglobulin E antibodies against proteins in egg yolk, such as alpha-livetin. It is often ordered alongside egg white testing when someone reacts to eggs and a provider wants to identify which part of the egg may be involved. Results are interpreted by a qualified healthcare provider.
What this test measures
Egg yolk contains a different set of proteins than egg white, and allergy to yolk alone is less common. One recognized yolk allergen, alpha-livetin (Gal d 5), is associated with bird-egg syndrome, in which people sensitized to bird feathers or droppings may experience symptoms after eating egg yolk. Reactions can include skin, respiratory, or digestive symptoms.
The assay measures specific IgE antibodies in a serum sample collected from a vein and typically reports a quantitative level with a graded class. Because yolk and white proteins differ, the test is frequently ordered together with egg white and component tests so that a provider can compare patterns across the whole egg.
People may order this test after reacting to eggs or when a provider suspects that yolk rather than white is relevant. It can also be included when bird-related allergy is being evaluated. A qualified healthcare provider should interpret results with your symptom history, since sensitization alone does not confirm a clinical allergy.
- Egg yolk specific IgE antibody
- Alpha-livetin (Gal d 5) component
- Egg white specific IgE
- Ovomucoid (Gal d 1) component
- Ovalbumin (Gal d 2) component
- Total serum IgE (when included)
- Graded IgE antibody class
Why people order this test
- Symptoms after eating eggs
- Evaluate suspected egg yolk allergy
- Investigate possible bird-egg syndrome
- Compare yolk and white sensitization patterns
- Follow-up testing after a previous result
- Gather information before a provider consultation
How to prepare
No fasting is usually required. A blood sample is collected from a vein, and the test can typically be performed at any time of day. Follow the laboratory instructions provided with your order.
Understanding your results
Results are generally available within 1-3 business days. A measurable IgE level suggests sensitization to egg yolk proteins, while a low result makes allergy less likely but does not rule it out. A qualified healthcare provider should interpret the result with your symptoms and history.

Frequently Asked Questions
How common is an egg yolk allergy?
Allergy to yolk alone is less common than reactions involving egg white proteins. Testing can help a provider see which proteins are relevant.
What is bird-egg syndrome?
It is a pattern in which sensitization to bird proteins is associated with reactions to egg yolk, often involving the alpha-livetin allergen. A provider can evaluate whether this applies to you.
How is the test performed?
It uses a small blood sample drawn from a vein, which the laboratory analyzes for specific IgE antibodies against egg yolk proteins.
Should egg white also be tested?
Testing both parts of the egg is common because it gives a provider a fuller picture of what may be driving symptoms.
Do I need to fast?
No. Fasting is not typically required for egg allergy blood testing.
