Egg White (f1) IgE details

Description

This test measures IgE antibodies specific to egg white proteins, used to check for an allergic sensitization to eggs — one of the most common food allergies in young children, though many children eventually outgrow it. A positive result, combined with a history of reactions after eating egg, supports an egg allergy diagnosis. Because egg white and egg yolk contain different proteins, some people react to one but not the other, and egg allergy is also relevant to certain vaccines that are manufactured using egg-based processes, which is sometimes a consideration your doctor will discuss.

Biomarkers

Egg White (f1) IgE

Panel

Food Allergy Basic Panel

$277.49

The Food Allergy Basic Panel measures IgE response to 6 common food allergens.

Sample type: Serum
Avg. sample processing time: 6 Business days
Require fasting: No

Biomarkers

Food and Tree Nut Allergy Panel

$147.99

This panel tests for specific IgE antibodies to 17 foods (with an emphasis on tree nuts) that are commonly associated with allergies. Allergen-specific serum IgE testing is considered comparable to skin testing and may be preferred in some clinical situations. However, a positive test result only indicates that a patient is sensitized to the allergen of concern. Many IgE-sensitized individuals do not develop any symptoms when exposed to the allergen. A diagnosis of allergy should only be made by a trained medical provider after conducting a thorough clinical evaluation.

Sample type: Serum
Avg. sample processing time: 4 Business days
Require fasting: No

Biomarkers

Regional Allergy Panel 2 + Food Allergy Basic Panel

$130.49

This panel combines the Regional Allergy Panel 2 and the Food Allergy Basic Panel to measure IgE antibody levels in response to 6 common food allergens and 21 airborne allergens. It helps identify potential allergic reactions to foods and environmental triggers such as pollen, mold, pet dander, and dust mites.
