Egg White IgE Level
This test measures IgE antibodies specific to egg white proteins. It helps identify allergic sensitisation and assess egg-related allergy risk.

Details about Egg White IgE Level
What is the Egg White IgE Level Test?
The Egg White IgE Level test measures allergen-specific immunoglobulin E (IgE) antibodies directed against proteins found in egg white. IgE antibodies are involved in immediate (Type I) allergic reactions and are produced when the immune system becomes sensitised to an allergen.
Egg white contains several allergenic proteins that are more commonly associated with allergic reactions than egg yolk. Measuring egg white–specific IgE helps determine whether symptoms may be immune-mediated rather than due to intolerance.
This test is widely used in the investigation of suspected food allergy in both children and adults.
Why do I need a test for Egg White IgE?
You may need this test if you experience symptoms shortly after consuming eggs or foods containing egg white. Egg allergy is one of the most common food allergies in childhood but can also persist into adulthood.
Testing helps confirm allergic sensitisation, guide dietary avoidance decisions and assess the risk of allergic reactions.
Symptoms and scenarios where testing is recommended:
- Hives or skin rash after eating eggs
- Swelling of lips, face or throat
- Abdominal pain, nausea or vomiting
- Wheezing or breathing difficulty
- Suspected food-triggered reactions
- Childhood eczema with food triggers
- Monitoring known egg allergy
- Allergy assessment before reintroduction
Benefits of the Egg White IgE Level Test
- Identifies egg white sensitisation
Detects immune-mediated allergy response. - Supports diagnosis of egg allergy
Helps differentiate allergy from intolerance. - Guides dietary management
Supports safe avoidance or reintroduction planning. - Assesses allergy severity risk
Higher IgE levels may correlate with reaction risk. - Useful in children and adults
Commonly used across all age groups. - Non-invasive blood-based test
No exposure to allergen required. - Supports allergy monitoring
Tracks changes in sensitisation over time. - Widely accepted allergy marker
Standard test in allergy assessment.
Step-by-Step: How Testing Works
Choose your preferred testing method
You can attend one of our UK partner clinics or arrange a home or hotel visit with a mobile phlebotomist.
Option 1 – In-Clinic Blood Draw
- Select your nearest UK clinic and book an appointment.
- A clinician or phlebotomist collects a venous blood sample.
- The sample is analysed for egg white–specific IgE antibodies.
- Results are delivered securely online.
Option 2 – Home or Hotel Phlebotomy (+£60)
- Book a UK-wide home or hotel visit at a convenient time.
- A trained phlebotomist collects your blood sample on-site.
- The sample is transported to the laboratory.
- Results are uploaded digitally without the need to travel.
Your Results Explained
Low / Negative Levels
Low or undetectable egg white IgE suggests no allergic sensitisation.
This makes IgE-mediated egg allergy unlikely.
Moderate Levels
Moderately elevated IgE levels indicate sensitisation.
Clinical symptoms are needed to confirm true allergy.
High Levels
High egg white IgE levels suggest a higher likelihood of clinical allergy.
Risk of immediate allergic reactions may be increased.
UK reference ranges and clinical interpretation vary by laboratory and age.

Follow these guidelines for accurate results
Sample Timing
Where possible, attend your blood test between 7am and 12pm. Please wait until any short-term illness or infection has fully resolved before testing. Avoid intense exercise for 24–48 hours beforehand, as this can affect certain markers.
Fasting & Hydration
Fasting is not always required, but some tests may recommend it. If fasting is advised, avoid food for 8–12 hours before your appointment and drink water only. Stay well hydrated, as this helps with sample collection and accuracy.
Medications & Supplements
Continue prescribed medications unless advised otherwise by your clinician. Avoid vitamin, mineral, or biotin supplements for at least 24–48 hours before your test, as these can interfere with results. If you are unsure about any medication or supplement, please let us know before your appointment.
Hormones & Menstrual Cycle
For hormone-related tests, timing within your menstrual cycle may be important. If relevant, follow any specific guidance provided on your test page.
If you have any questions or special circumstances, our team is happy to advise before your appointment.
