Overview

The diagnosis of varicella is primarily clinical. In a non-immunized individual with the appropriate appearing rash occurring in "crops", no further investigation would normally be undertaken. For further investigation, examination of the fluid within the vesicles, or by testing blood for evidence of an acute immunologic response. Vesicle fluid can be examined with a Tsanck smear, or better with examination for direct fluorescent antibody. The fluid can also be "cultured", whereby attempts are made to grow the virus from a fluid sample. Blood tests can be used to identify a response to acute infection (IgM) or previous infection and subsequent immunity (IgE).^[1]. Prenatal diagnosis of foetal varicella infection can be performed using ultrasound, though a delay of 5 weeks following primary maternal infection is advised. A PCR (DNA) test of the mother's amniotic fluid can also be performed, though the risk of spontaneous abortion due to the amniocentesis procedure is higher than the risk of the baby developing foetal varicella syndrome.

The skin lesions of breakthrough varicella can be macular rather than vesicular. They are rarely bullous or hemorrhagic, and residual scarring is less common.
