Reference Values

Negative

Interpretation

A positive result indicates that parvovirus B19 DNA is present in the clinical sample. However, a positive result does not differentiate between actively replicating virus, transient infection that may be asymptomatic, or the presence of remnant viral nucleic acid.

 

A negative result suggests the absence of parvovirus B19 infection.
