Test ID UBKQN BK Virus DNA Detection and Quantification, Random, Urine

Specimen Required

Supplies: COBAS PCR - Urine Sample Kit (T903)

Container/Tube: cobas PCR urine tube

Specimen Volume: 4.3 mL

Collection Instructions:

1. Collect random urine into a sterile, plastic, preservative-free container.

2. Transfer 4.3 mL of urine into the cobas PCR urine sample tube using the disposable pipette provided within 24 hours of collection. The correct volume of urine has been added when the fluid level is between the black fill lines on the urine transport tube. Place the labels on the transport tube so the black fill lines are still visible for volume confirmation at Mayo Clinic Laboratories.

3. Transport and store urine specimen transport container at 2 to 30° C (refrigerate is preferred temperature).

Additional Information: cobas PCR media contains guanidine hydrochloride. Do not allow these tubes to come in direct contact with sodium hypochlorite (bleach) or other highly reactive reagents such as acids and bases. These mixtures can release a noxious gas.
