Egg White Allergy Test (IgE) — Detect Egg Protein Sensitivity

Egg white allergy is one of the most common food allergies in children, but it can also affect adults. The proteins in egg white, particularly ovalbumin and ovomucoid, are the main triggers. Reactions can range from mild skin symptoms to severe anaphylaxis. This IgE blood test helps confirm whether your immune system reacts to egg white proteins.

Why Test Egg White Allergy Test?

Testing is recommended if you experience skin rashes, digestive symptoms, or respiratory problems after eating eggs or foods containing egg. It is especially important for children with suspected food allergies and for anyone whose symptoms are unclear or could be attributed to multiple foods.

What Do High Egg White Allergy Test Levels Mean?

High IgE levels indicate sensitisation to egg white proteins, supporting a diagnosis of egg allergy. The level of IgE may help estimate the likelihood and severity of allergic reactions upon egg consumption.

What Do Low Egg White Allergy Test Levels Mean?

Low or undetectable IgE levels make an IgE-mediated egg white allergy unlikely. However, non-IgE-mediated egg sensitivities or reactions to other egg components (such as egg yolk) cannot be excluded.

Symptoms to Watch For

  • Skin rashes or hives after eating eggs
  • Swelling of the face, lips, or throat
  • Nausea, vomiting, or stomach pain
  • Nasal congestion or sneezing
  • Wheezing or breathing difficulties
  • Eczema flare-ups linked to egg consumption

Who Should Get Tested?

  • Children with suspected egg allergy
  • Adults who develop symptoms after eating eggs
  • People with eczema that worsens after egg consumption
  • Anyone needing to confirm egg allergy before vaccination (some vaccines contain egg protein)

How to Prepare for Your Test

No special preparation is required. No fasting needed. Bring your ID to the sampling location. Bring valid ID to your appointment.

Frequently Asked Questions

Can I eat cooked eggs if I have an egg allergy?
Some people with egg allergy can tolerate well-cooked or baked egg, as heating alters certain proteins. However, this should only be tested under medical supervision.
Do children outgrow egg allergies?
Yes, many children outgrow egg allergy by school age, especially if they tolerate baked egg early on. Regular follow-up testing helps monitor progress.
Are flu vaccines safe for people with egg allergy?
Most modern flu vaccines contain very little egg protein and are considered safe for people with egg allergy. Discuss with your doctor if you have a severe allergy.
