Hepatitis D Quantitative PCR (Sendout)

Interpretive Data:

The quantitative range of this assay is 2.0-6.7 log IU/mL (92 - 4,600,000 IU/mL).

A negative result (less than 2.0 log IU/mL or less than 92 IU/mL) does not rule out the presence of PCR inhibitors in the patient specimen or HDV RNA concentrations below the level of detection of the test. Inhibition may also lead to underestimation of viral quantitation.

3 mL blood in GOLD TOP tube (SST)

Note: This test requires a dedicated tube and cannot be shared.

Outside Laboratories:

• Preferred: Centrifuge sample and freeze in unopened SST container at -20°C.
• Note: Serum submitted in an unopened tube is preferred due to potential contamination. However, ARUP will accept sterile aliquots. If sending, note "sterile aliquot" on the requisition to prevent delays.

Stability: Frozen: 30 days; Refrigerated: 1 week; Ambient: 24 hours.
