Use to detect and quantify BK virus in urine. For additional information regarding this test, please visit BK Virus by Quantitative NAAT.
Quantitative Polymerase Chain Reaction
New York DOH Approval Status
Immediately transfer urine to a cobas® PCR urine sample tube (ARUP supply #58056 PK/100 or #58084 PK/10) available online through eSupply using ARUP Connect or contact Client Services at 800-522-2787. Liquid level must be between the black fill lines on the tube.
Under- or over-filled tubes. Specimens in any transport media other than indicated above. Neat urine. Plasma (refer to BK Virus by Quantitative NAAT, Plasma, ARUP test code 3006076).
Urine in media: Ambient: 90 days; Refrigerated: 90 days; Frozen: Unacceptable.
The quantitative range of this assay is 2.30-8.00 log IU/mL (200-100,000,000 IU/mL).
An interpretation of "Not Detected" does not rule out the presence of inhibitors or BKV DNA concentration below the level of detection of the assay. Care should be taken in the interpretation of any single viral load determination.
International standardization has improved comparability of assay results across laboratories, but discrepancies still exist due to commutability issues with the standard.
The limit of quantification for this assay is 2.30 log IU/mL (200 IU/mL). If the assay DETECTED the presence of the virus but was not able to accurately quantify the viral load, the test result will be reported as "Not Quantified, Detected".
