Order Egg Yolk Allergy Test | Food AllergyAn egg yolk allergy test measures the presence of immunoglobulin E (IgE) antibodies directed specifically at proteins found in the yellow portion of a cracked egg. This blood-based assay helps distinguish sensitization to egg yolk from reactions to egg white, a distinction that matters because the two fractions contain different allergenic proteins.
About Egg Yolk Allergy Test | Food Allergy in Foster City
Egg yolk allergy testing focuses on a defined fraction of the egg rather than the whole food.
The test uses a blood sample to quantify IgE antibodies that bind to egg yolk proteins. IgE is the antibody class most closely associated with immediate hypersensitivity reactions, so its presence can indicate that the immune system has been primed to respond to yolk exposure.
Egg white and egg yolk differ in their protein composition. Ovalbumin, the most abundant protein in egg white, is not present in the yolk, while yolk contains proteins such as livetins and lipoproteins. A yolk-specific test therefore provides information that a whole-egg test may not resolve.
Results are typically reported as a quantitative value alongside a reference range established by the performing laboratory. A detectable IgE level suggests sensitization, but sensitization and clinical allergy are not identical; a clinician interprets the result together with the patient's history and, when appropriate, other diagnostic findings.
