BK Virus by PCR Quantitative, Urine

General Information

Lab Name

BK Virus PCR Quant, Urine

Lab Code

UBKQN

Epic Name

BK Virus PCR Quant, Urine

Description

The UW Clinical Virology Laboratory in the Department of Laboratory Medicine and Pathology incorporates the FDA approved Roche cobas® BKV Quantitative assay for the detection of BK polyomavirus (BKV) using real-time PCR amplification.

The lower limit of detection, LoD (the minimum virus level that gives a positive result in 95% of replicates), is 12.2 IU/mL, and the lower limit of quantitation (LLoQ) is 200 IU/mL.

A conversion factor of 1.0 Log10 IU/mL is equivalent to 1.0 Log10 copies/mL.

The Roche cobas® BKV assay uses primers specific for the BKV VP2 region and the BKV small t-antigen region.

For Tissue Biopsy, Bone Marrow, Swab, or Cellular fluid (e.g. BAL or Washing), see BK Virus by PCR Qualitative [BKVQL].
