Parvovirus B19 by PCR

Test Codes

ARUP #60043, EPIC: LAB6124, SOFT: XPARV

Specimen Collection Criteria

Collect (preferred specimen): One Lavender-top EDTA tube, Gold-top SST tube, or plain Red-top tube.
Also acceptable: Amniotic fluid, Cerebrospinal Fluid (CSF), Synovial Fluid, paraffin-embedded tissue, or fresh tissue.

Specimen source is required.

Physician Office/Draw Specimen Preparation

  • Centrifuge to separate plasma or serum from cells. Transfer serum or plasma to a plastic transport tube and freeze (-20°C/-4°F or below).
  • Maintain fluid specimens frozen (-20°C/-4°F or below) prior to transport.
  • Fresh tissue must be frozen (-20°C/-4°F or below) immediately.
  • Paraffin-embedded tissue should be maintained at room temperature (20-26°C or 68-78.8°F).

Preparation for Courier Transport

Transport: 1.0 mL serum, plasma, fluid, or fresh tissue, frozen (-20°C/-4°F or below), or paraffin-embedded tissue, at room temperature (20-26°C or 68-78.8°F). (Minimum: 0.5 mL)

Rejection Criteria

  • Heparinized specimens.
  • Frozen whole blood.
  • Bone marrow specimens.
  • Specimens in non-sterile or leaking containers.
  • Specimens not collected and processed as indicated.

In-Lab Processing

  • Centrifuge to separate plasma or serum from cells. Transfer serum or plasma to a plastic transport tube and freeze (-20°C/-4°F or below).
  • Maintain fluid specimens frozen (-20°C/-4°F or below) prior to transport.
  • Fresh tissue must be frozen (-20°C/-4°F or below) immediately.
  • Paraffin-embedded tissue should be maintained at room temperature (20-26°C or 68-78.8°F).

Transport: 1.0 mL serum, plasma, fluid, or fresh tissue, frozen (-20°C/-4°F or below), or paraffin-embedded tissue, at room temperature (20-26°C or 68-78.8°F). (Minimum: 0.5 mL)

Room Temperature (20-26°C or 68-78.8°F): 24 hours
Refrigerated (2-8°C or 36-46°F): 5 days 
Frozen (-20°C/-4°F or below): 6 months

Specimen Storage in Department Prior to Disposal:

Specimen retention time is determined by the policy of the reference laboratory. Contact the Send Outs Laboratory with any questions. 

Performed

Monday, Wednesday, Friday.
Results available in 2-5 days.

Reference Range

Negative: Parvovirus B19 DNA not detected by PCR.
Positive: Parvovirus B19 DNA detected by PCR.

Test Methodology

Qualitative Polymerase Chain Reaction (PCR).

Interpretation

  • 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.
  • This test is performed pursuant to an agreement with Roche Molecular Systems, Inc.
