Parvovirus B19 PCR


This qualitative PCR assay is used for the detection of Parvovirus B19, which can cause the childhood infection slapped cheek (or fifth disease), as well as more serious aplastic crisis, persistent anaemia, myocarditis, hepatitis and, rarely, encephalitis. Infection in pregnancy can result in hydrops fetalis. Parvovirus B19 DNA can persist for several months following infection, meaning results from this assay must be interpreted with caution. Serological testing (see below) can be of assistance in such cases.

Also known as

Slapped cheek, fifth disease, erythema infectiosum, hydrops fetalis
