Eosinophilic esophagitis

Eosinophilic esophagitis involves a buildup of white blood cells in the lining of your esophagus. The esophagus is the tube that carries food from your mouth to your stomach. The buildup of white blood cells (called eosinophils) is due to a reaction to foods, allergens, or acid reflux.

Esophagus

The esophagus connects the nose and mouth with the stomach. The epiglottis folds over the trachea when a swallow occurs, to prevent the swallowed substance from being inhaled into the lungs. When a person is unable to swallow because of illness or coma, a tube may be inserted either through the mouth or nose, past the epiglottis, into the esophagus and into the stomach. Nutrients will be passed through the tube directly into the stomach.

Allergy skin prick or scratch test

One of the most common methods of allergy testing is the scratch test or skin prick test. The test involves placing a small amount of the suspected allergy-causing substance (allergen) on the skin (usually the forearm, upper arm, or the back), and then scratching or pricking the skin so that the allergen is introduced under the skin surface. The skin is observed closely for signs of a reaction, which usually includes swelling and redness of the site. With this test, several suspected allergens can be tested at the same time, and results are usually obtained within about 20 minutes.

Intradermal allergy test reactions

Intradermal allergy testing is another method of skin testing to help determine whether an individual is allergic to a specific allergen. The test involves injection of a small amount of the suspected allergen under the surface of the skin. After about 20 minutes the area is examined for a reaction at the site. A typical reaction looks like a small hive with swelling and redness. The intradermal test is more sensitive than the skin prick test and can usually provide more consistent results.
