What Is Lichen Planus?
9. Diagnosis
Your doctor will need to ask you about your symptoms, and they will also likely want to perform a physical exam of the affected areas. In many cases, a diagnosis can be made through this information alone, but tests may still be requested to get a confirmed diagnosis of the condition.
Diagnosis will also often involve testing for potential triggers such as hepatitis C, and allergies. In some cases, a small sample of an affected area will also need to be taken. This sample will then be examined so experts can look for signs that are typically caused by lichen planus.
