Clinical Info

This test is intended for use as an aid in the management of BKV in solid organ transplant patients and in hematopoietic stem cell transplant patients, as well as for monitoring BKV antiviral therapy.

Specimen Sources

Urine, Clean Catch

Specimen Types

Urine

Specimen Volume

Container

Random urine or cobas® PCR Media tube

Collection Instructions

Container/Tube: Random Urine or Urine stabilized in Cobas® PCR Media
Specimen : 10 mL of urine (0.5 mL min)
If using the Cobas® PCR Media Fill urine to fall within the 2 black lines on the cobas® PCR
Media tube.
Transport Temperature: Refrigerated
Stability: 2 days Refrigerated
90 Days if using the Cobas® PCR Media tube
Note: Specimen must be received within 48 hours of collection.
Collection instructions if using the Cobas® PCR Media tube
Collect a urine sample in a sterile cup. Transfer the urine using the transfer pipette included in the cobas® PCR Urine Sample Kit to the cobas® PCR Media tube. Transfer enough urine so the level falls between the two black lines on the cobas® PCR Media tube. Cap the tube tightly and invert 5 times to mix the sample.

Transport Instructions

Specimen must be received within 48 hours of collection,  if not, transferred into the Cobas(R) PCR Media tube

Specimen Stability

2 days Refrigerated
90 Days if using the Cobas(R) PCR media tube

Result Interpretation

The linear range of the assay is 200-100,000,000 IU/mL (2.30 to 8.0 log10 IU/mL). 

               Assay lower limit of quantification (LLOQ) is 200 IU/mL (2.30 log10 IU/mL)

                Below the LLOQ will be reported as Detected <200 IU/mL (<2.30 log10 IU/mL)
