Answer

Answer

The diagnosis of HZO is primarily by history and examination. However, baseline complete blood count, electrolytes, glucose, blood urea nitrogen, and creatine may be necessary prior to starting antiviral drugs.

When a clear diagnosis cannot be made, a noncontrast CT scan should be considered to evaluate for other causes of new-onset headache.
