Interpretive Data

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.

Compliance Statement B: For laboratory developed tests not using a RUO kit, and for FDA approved, cleared or 510(k) exempt assays with alterations. This test was developed and its performance characteristics determined by ARUP Laboratories. The U. S. Food and Drug Administration has not approved or cleared this test; however, FDA clearance or approval is not currently required for clinical use. The results are not intended to be used as the sole means for clinical diagnosis or patient management decisions.

Note

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."
