Chickenpox Diagnosis

Diagnosis of Chickenpox

The diagnosis of Chickenpox is mainly based on the symptoms and signs, with common early-stage symptoms that are followed by a characteristic rash. The examination of the fluid finalizes confirmation of the diagnosis. It is done throughout the vesicles of the rash, or just by testing blood for evidence of immunologic response. For instance, vesicular fluid can be monitored and tested with a Tzanck smear, or by checking for fluorescent antibody. The liquid often can be "cultured," by which it attempts to help the growth of the virus from a fluid sample. Blood tests are generally used to identify and discover a response to acute infection (IgM) or subsequent immunity (IgG) and previous infection.

Prenatal Diagnosis

Prenatal diagnosis of fetal varicella infection may be made by using ultrasound, within a delay of around five weeks, then by following foremost maternal infection. A PCR (DNA) test of the amniotic fluid of mothers' can also be performed, under the risk of abortion. Due to the amniocentesis procedure, the risk of developing the syndrome of fetal Varicella is higher.
