Additional Codes:

BKDNA Plasma

Collection:

Specimen: Blood

Container: White PPT (Plasma Preparation Tube) or Lavender (EDTA) tube. A separate tube is required if multiple tests are ordered to be collected in a Lavender tube.  Microtainers unacceptable.

Assay:

Abbott Alinity M

Request Form:

Routine Laboratory Request Form

Send To:

UMC MAIN LABORATORY Specimen Receiving – EH319 Children’s Hospital

Reference Interval:

Not Detected 

Interpretive Data:

The Alinity m BK Virus (BKV) assay utilizes real-time polymerase chain reaction (PCR) to amplify and detect BKV genomic DNA in plasma specimens. The 
linear range of the assay is 50-1,000,000,000 IU/mL. 

Not Detected: BKV DNA is not detected. 
< 50 IU/mL: The amount of BKV DNA is detectable but below the lower limit of quantitation of the assay (50 IU/mL). 
50-1,000,000,000 IU/mL: BKV DNA was detected within the linear range of the assay and will be reported as a value. 
> 1,000,000,000 IU/mL: The amount of BKV DNA is detectable but above the upper limit of quantitation of the assay (1,000,000,000 IU/mL)
