BK Virus, Quantitative PCR, Urine : 2002310

Mnemonic: BK QNT URN

Methodology: Quantitative Real-Time Polymerase Chain Reaction
Performed: Sun-Sat
Reported: 1-5 days
Specimen Required: Collect: Urine.

Specimen Preparation: Transfer 1 mL urine to a sterile container. (Min: 0.5 mL).

Storage/Transport Temperature: Frozen.

Remarks: Specimen source required.

Unacceptable Conditions: Plasma, serum or whole blood (refer to BK Virus, Quantitative PCR, Blood, ARUP test code 2002304).

Stability (collection to initiation of testing): Ambient: 24 hours; Refrigerated: 5 days; Frozen: 1 month.

Reference Interval:
Not detected
Interpretive Data: The quantitative range of this assay is 2.6-8.6 log copies/mL (390-390,000,000 copies/mL).

A negative result (less than 2.6 log copies/mL or less than 390 copies/mL) does not rule out the presence of PCR inhibitors in the patient specimen or BK virus DNA concentrations below the level of detection of the assay. Inhibition may also lead to underestimation of viral quantitation.

No international standard is currently available for calibration of this assay. Caution should be taken when interpreting results generated by different assay methodologies.

Refer to Statement A under Testing Information at http://www.aruplab.com.
Note: The limit of quantification for this DNA assay is 2.6 log copies/mL (390 copies/mL). If the assay DID NOT DETECT the virus, the test result will be reported as "< 2.6 log copies/mL (< 390 copies/mL)." If the assay DETECTED the presence of the virus but was not able to accurately quantify the number of copies, the test result will be reported as "Not Quantified."
CPT Code(s): 87799
