Skin test methodology

Skin testing is a medical process used to determine if someone has allergies or sensitivities to certain substances, like foods or environmental factors. During the test, a small amount of the substance is placed on or just under the skin, usually on the forearm or back. The area is then observed for reactions, such as redness or swelling, which indicate an allergy. This method is quick, minimally invasive, and helps healthcare providers identify what triggers a person's allergic reactions, guiding them in managing their symptoms effectively.
