Test Code PVPQP Parvovirus B19 Quantitative Real-time PCR (Plasma)
Clinical Indications
Parvovirus B19 manifests itself as an acute or chronic
hematological disorder in immunocompromised patients. It can
cause
persistent anemia, sometimes associated with leukopenia and
thrombocytopenia. Pediatric transplant patients are at risk for
chronic infections, which can be associated with lung and/or
renal
disorders. Quantitative DNA PCR can be used to detect the presence of the
virus,
track the course of infection, and monitor response to
treatment.
