An egg white allergy test uses a blood sample to measure allergen-specific IgE antibodies against proteins in egg white, the clear portion of a cracked egg. Egg white contains several of the best-known egg allergens, including ovalbumin and ovomucoid, so it is often tested when an egg allergy is suspected. A provider may order it after a reaction to eggs or egg-containing foods, or as part of a broader food allergy panel. The test is a screening tool interpreted together with symptoms, timing, and medical history.

• People who develop hives, itching, or swelling after eating eggs
• Individuals with digestive upset, vomiting, or diarrhea after egg-containing foods
• Those with eczema or skin reactions that flare after eating eggs
• People who have reacted to baked goods, sauces, or dressings made with egg
• Anyone being evaluated as part of a broader food allergy workup

• Egg white-specific IgE Antibodies produced against egg white proteins; used to assess sensitization to the white portion of an egg.

• No fasting is required for this IgE allergy test
• The blood sample can be collected at any time of day
• Tell the provider about medications such as antihistamines
• No special diet is needed beforehand

Results are reported as an IgE level or class for egg white. An elevated value may indicate sensitization to egg white proteins, but a positive result alone does not confirm a clinical allergy. A low or undetectable level makes reactivity to egg white less likely, though it does not rule out allergy to egg yolk or to proteins such as ovalbumin or ovomucoid. Because cooking can change how egg proteins are recognized, a provider may consider baked egg tolerance. Discuss results with a healthcare provider.
