FAQ
What does this test measure? It detects IgE antibodies specific to egg white proteins in your blood, indicating allergic sensitization.
Do I need to stop eating eggs before testing? No preparation is needed. You can eat normally before your blood draw.
How accurate is this test? ImmunoCAP technology provides highly accurate results, but clinical correlation with symptoms is important.
Can this test predict reaction severity? IgE levels indicate allergy likelihood but don't perfectly predict how severe reactions will be.
What if I'm allergic to whole eggs, not just whites? Consider our Whole Egg Allergy test or Egg Component panel for comprehensive screening.
More Details
What is the purpose of this test?
This test measures specific IgE antibodies against egg white proteins to confirm or rule out an egg white allergy. Using advanced ImmunoCAP technology, it detects your immune system's response to major egg white allergens like ovomucoid and ovalbumin (Mayo Clinic 2024). The results help identify if egg whites are causing your allergic symptoms and guide appropriate management strategies.
Who would benefit from this test?
You should consider this test if you experience allergic reactions after eating eggs or egg-containing foods. It's particularly valuable for individuals with symptoms like hives, respiratory issues, digestive problems, or anaphylaxis following egg consumption (Thermo Fisher 2025). Parents of children with unexplained allergic reactions or those with family histories of food allergies also benefit from this screening.
When should I order an Egg White Allergy IgE Blood Test?
Order this test when you suspect egg white allergy based on symptoms occurring within minutes to hours of egg consumption. Common symptoms include tingling around the mouth, swelling, hives, digestive discomfort, respiratory issues, or severe reactions like anaphylaxis. Early testing prevents dangerous exposure and enables proper dietary management (Walk-In Lab 2024).
How do I interpret the results?
IgE < 0.35 kU/L (Class 0)
- What It Means: No sensitization detected
- Typical Action: Egg whites likely safe to consume
IgE 0.35–0.69 kU/L (Class 1)
- What It Means: Low sensitization
- Typical Action: Monitor symptoms, may tolerate eggs
IgE 0.70–3.49 kU/L (Class 2)
- What It Means: Moderate sensitization
- Typical Action: Avoid egg whites, consult allergist
IgE 3.50–17.4 kU/L (Class 3)
- What It Means: High sensitization
- Typical Action: Strict avoidance, carry epinephrine
IgE 17.5–49.9 kU/L (Class 4)
- What It Means: Very high sensitization
- Typical Action: Complete avoidance, emergency plan
IgE 50–100 kU/L (Class 5)
- What It Means: Extremely high sensitization
- Typical Action: Strict avoidance, specialist care
IgE > 100 kU/L (Class 6)
- What It Means: Maximum sensitization
- Typical Action: Complete avoidance, emergency plan
Results must be interpreted alongside your clinical symptoms and medical history for accurate diagnosis (NCBI 2013).
Disclaimer: Reference ranges may vary by laboratory. Listed ranges are general guidelines and may differ from those used by the performing lab. Always consult your healthcare provider for interpretation.
Pre-test preparation
No special preparation is required for this test. You don't need to fast, avoid medications, or make dietary changes beforehand. Simply schedule your blood draw appointment and arrive as normal. The test requires only a small blood sample drawn from your arm, similar to routine blood work.
How often should I get tested?
- Initial allergy screening – Once, then as symptoms warrant
- Monitoring during immunotherapy – Every 6–12 months
- Children with egg allergy – Annually to track tolerance development
- Adults with stable allergy – Every 2–3 years or if symptoms change
- After allergic reaction – Retest in 3–6 months if considering reintroduction
Why early detection matters
Early detection of egg white allergy prevents potentially life-threatening reactions and improves quality of life. Egg allergy affects up to 2% of children globally, making it one of the most common food allergies (NCBI 2013). Prompt diagnosis enables proper avoidance strategies, emergency preparedness, and appropriate medical management to prevent severe reactions including anaphylaxis.
