In general, laboratory studies are unnecessary for diagnosis, because varicella is clinically obvious. However, some tests and procedures may be helpful in confirming the diagnosis or identifying complications. Imaging studies are typically not required for varicella unless secondary complications are a concern (eg, chest radiography for varicella pneumonia).
