Diagnose and monitor human parvovirus infection in patient with suppressed or delayed immune response.
Quantitative Polymerase Chain Reaction
Mon, Wed, Fri
Lavender (EDTA), pink (K2EDTA), or serum separator tube (SST).
Separate serum or plasma from cells. Transfer 1 mL serum, plasma to a sterile container. (Min: 0.5 mL)
Specimen source required.
Ambient: 24 hours; Refrigerated: 5 days; Frozen: 6 months
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.
This test was developed and its performance characteristics determined by ARUP Laboratories. It has not been cleared or approved by the US Food and Drug Administration. This test was performed in a CLIA certified laboratory and is intended for clinical purposes.
Laboratory Developed Test (LDT)
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."
