Your doctor will ask about your symptoms and medical history, and perform a physical examination. Chickenpox is usually diagnosed based on the telltale rash. Blood and laboratory tests to identify the varicella zoster virus (VZV) are available for use in questionable cases but are rarely necessary.
Blood and laboratory tests—several tests are available that may help confirm the diagnosis of chickenpox, including:
