Confirm and quantify the presence of hepatitis E virus.
Quantitative Polymerase Chain Reaction
Lavender (EDTA), pink (K2EDTA) or Serum separator tube (SST).
Separate from cells. Transfer 1 mL serum or plasma to an ARUP Standard Transport Tube. (Min: 0.5 mL)
Additional information required: Specimen source
Ambient: 24 hours; Refrigerated: 1 week; Frozen: 1 week
The quantitative range of this assay is 3.3- 8.3 log IU/mL (1,800 - 180,000,000 IU/mL). One IU/mL of HEV RNA is approximately 2.25 copies/mL.
A negative result (less than 3.3 log IU/mL or less than 1,800 IU/mL) does not rule out the presence of PCR inhibitors in the patient specimen or HEV 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 RNA test is 3.3 log IU/mL (1,800 IU/mL). If the test DID NOT DETECT the virus, the test result will be reported as "< 3.3 log IU/mL (< 1,800 IU/mL)." If the test DETECTED the presence of the virus but was not able to accurately quantify the number of international units, the test result will be reported as "Not Quantified."
