The Egg Whites Allergy Test is a blood test that checks for an allergic response to proteins found in egg whites. It is typically ordered when a person has had allergic symptoms after eating eggs or egg-containing foods, or when a doctor wants to confirm or rule out an egg white allergy.

What it measures

  • Egg white-specific IgE — Measures antibodies that target proteins in egg whites.
  • Ovomucoid-specific IgE — Checks for a reaction to a major egg white protein that is often heat-stable.
  • Ovalbumin-specific IgE — Checks for a reaction to another common egg white protein.
  • Conalbumin (ovotransferrin)-specific IgE — Checks for a reaction to a third egg white protein.
  • Lysozyme-specific IgE — Checks for a reaction to a less common egg white protein.

Who it is for

This test is usually ordered by an allergist, immunologist, or primary care doctor for people who have had symptoms such as hives, stomach upset, or breathing problems after eating eggs.

Preparation

No fasting or special preparation is needed for this blood test. You can eat and drink normally before the appointment.

Results and what they mean

Results are reported as a number for each specific IgE marker, often along with a reference range. A clinician interprets these numbers together with your symptoms and history; a positive result alone does not always mean you have an allergy. This is general information, not medical advice.

Frequently asked questions

Does a positive result mean I am allergic to eggs?

Not always. A positive result shows that your immune system has made antibodies to egg white proteins, but you may not have symptoms. Your doctor will consider your history and other tests.

Can this test tell me if I will outgrow an egg allergy?

It can help track changes over time, but it cannot predict whether you will outgrow the allergy. Your doctor will monitor your symptoms and may repeat testing.

Do I need to avoid eating eggs before the test?

No. You do not need to avoid eggs before this blood test. In fact, avoiding eggs will not change the antibody levels that the test measures.

How long does it take to get results?

Results are usually available within 1 to 3 business days. Your doctor's office will contact you to discuss the results.
