Interpretive Data
The quantitative range of this test is 2.0-8.0 log IU/mL (100-100,000,000 IU/mL).

A negative result (less than 2.0 log IU/mL or less than 100 IU/mL) does not rule out the presence of PCR inhibitors in the patient specimen or Parvovirus DNA concentrations below the level of detection of the test. Inhibition may also lead to underestimation of viral quantitation.

Compliance Statement B: 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 DNA test is 2.0 log IU/mL (100 IU/mL). If the test DID NOT DETECT the virus, the test result will be reported as "< 2.0 log IU/mL (< 100 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."
