An ovalbumin allergy test uses a blood sample to measure allergen-specific IgE antibodies against ovalbumin, a protein found in egg white and the most abundant protein in egg white overall. Ovalbumin is also used in the manufacture of some vaccines, so it may be relevant when an egg-related reaction is being investigated. The test is a screening tool for suspected egg allergy rather than a diagnosis by itself. A provider may order it after a reaction to eggs or as a follow-up to a positive egg white test. Results are read with symptoms and history.

• Ovalbumin-specific IgE Antibodies produced against ovalbumin, a major protein in egg white; used to assess sensitization to this specific egg protein.

• 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 with a positive egg white test who need component-level detail
• Anyone being evaluated for possible egg protein sensitization

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

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