Patch testing primarily helps to diagnose skin allergies, says WebMD. A doctor performs the test by applying the suspected allergen to the skin with an adhesive patch. It stays on the skin for a specified amount of time, and then the doctor removes the suspected allergen and inspects the skin. The doctor takes a culture to identify a virus, bacteria or fungus that is causing an infection. The culture may include biopsies, contents of pus bumps, hair or skin scrapings.
Skin biopsies help diagnose benign or malignant skin conditions. A doctor conducts this procedure after applying a local anesthetic. If necessary, the area is closed with stitches. The doctor sends the skin sample to a laboratory for analysis, according to WebMD. Additional tests to diagnosis skin conditions are diascopy, the Tzanck test and Wood's light, states the Merck Manual.Learn more about Skin Conditions
