Diagnosis

In most cases, your doctor can diagnose dyshidrosis based on a physical exam. No lab test can specifically confirm a diagnosis of dyshidrosis, but your doctor may suggest tests to rule out other skin problems that have similar symptoms.

For example, a scraping of your skin can be tested for the type of fungus that causes athlete's foot. Skin allergies and sensitivities can be revealed by exposing patches of your skin to various substances.
