Confirm and quantify the presence of hepatitis D virus.
Quantitative Polymerase Chain Reaction
Serum Separator Tube (SST).
Separate serum from cells. Transport 1 mL serum in a sterile container. (Min: 0.5 mL)
Specimen source required.
Ambient: 24 hours; Refrigerated: 1 week; Frozen: 4 months
The quantitative range of this assay is 2.1-6.8 log IU/mL (120 - 5,800,000 IU/mL).
A negative result (less than 2.1 log IU/mL or less than 120 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.
Laboratory Developed Test (LDT)
The limit of quantification for this test is 2.1 log IU/mL (120 IU/mL). If the test DID NOT DETECT the virus, the result will be reported as "< 2.1 log IU/mL (< 120 IU/mL)." If the test DETECTED the presence of the virus but was not able to accurately quantify the number of copies, the result will be reported as "Not Quantified."
