Test Details
Methodology
Real-time polymerase chain reaction (PCR)
Result Turnaround Time
2 - 4 days
Turnaround time is defined as the usual number of days from the date of pickup of a specimen for testing to when the result is released to the ordering provider. In some cases, additional time should be allowed for additional confirmatory or additional reflex tests. Testing schedules may vary.
Use
Detection and quantitation of BK virus (BKV) in EDTA plasma is to be used as an aid in the diagnosis and management of BK virus infections. This assay is traceable to the 1st WHO International Standard for BK Virus for Nucleic Acid Amplification Techniques (NAT)-based assays.

Container
Ship in a screw-cap polypropylene frozen transport tube.
Collection Instructions
Collect specimen in lavender-top (EDTA) tube. Centrifuge specimen within 24 hours of collection, remove plasma and transfer to a polypropylene screw-capped tube, and freeze. Ship frozen. To avoid delays in turnaround time when requesting multiple tests on frozen samples, please submit separate frozen specimens for each test requested.
