Diagnosis of Chickenpox
► 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.
