Diagnosis of Chickenpox
The diagnosis is made by observing the symptoms and the typical appearance of the rash.
- The blisters are like dew drops on the petal of a flower. Except that the dew drop is on a background of red rash.
- Laboratory diagnosis is seldom required because of clear-cut clinical signs.
- Examination of the fluid present within the lesion under the microscope shows characteristic round particles. Scrapings from the floor of the lesion show, what are called, giant cells.
