Egg Yolk (f75) IgE details
What Egg Yolk (f75) IgE shows
Egg yolk contains different proteins from egg white, and although egg white proteins usually cause most egg allergy, some people are sensitized to yolk proteins too. This test measures IgE antibodies to egg yolk. A positive result can help explain reactions after eating egg or egg-containing foods, and some yolk proteins are shared with bird feathers and droppings, so sensitization to birds can also show up here. It is usually interpreted together with egg white and other egg tests. IgE shows sensitization, not necessarily allergy, so the result needs to be read against your symptoms and history.
