# Egg Yolk

> This test measures the level of IgE antibodies in your blood that react specifically to proteins found in egg yolks. It helps show whether your immune system views egg yolk as a threat, which is useful for investigating symptoms like hives, swelling, or digestive issues after eating eggs. By identifying this specific reaction, the test helps determine if egg yolk is a likely cause of your symptoms compared to other foods or egg whites. However, this test alone cannot diagnose an allergy, as some people have antibodies without experiencing actual symptoms when they eat eggs.
