Polymerase Chain Reaction (PCR) - Clinical Significance:
Refer to:
- Reference Range:
- Parvovirus B 19, by PCR
- Negative – Parvovirus B19 DNA not detected by PCR
Positive – Parvovirus B19 DNA detected by PCR - Interpretive Data:
- A negative result does not rule out the presence of PCR inhibitors in the patient specimen or Parvovirus DNA in concentrations below the level of detection of the assay.
