THIS TEST IS USED TO DETERMINE THE PRESENCE OF BK VIRUS DNA IN PATIENT'S SPECIMENS. DETECTION OF THE VIRUS IN THESE SPECIMENS MAY BE INDICATIVE OF AN ACTIVE INFECTION, AS PCR DETECTS THE PRESENCE OF THE VIRUS, AND NOT THE HOST'S REACTION TO THE VIRUS. POLYOMAVIRUS BK DNA DETECTION IN URINE OR PLASMA IS ASSOCIATED WITH AN INCREASED RISK OF GRAFT REJECTION IN RENAL RECIPIENTS. QUANTITATIVE TESTING MAY INDICATE CHANGE IN RISK OVER TIME. THIS IS A QUANTITATIVE MOLECULAR TEST, WITH A LINEAR RANGE OF 500-500,000,000 copies/mL.

Plasma:
Collect blood in sterile tubes containing EDTA as an anticoagulant,
or in Plasma Preparation Tube (PPT). Collect whole blood at room
temperature and separate plasma from cells within 2 hours of
collection. Transfer plasma to sterile, plastic, screw-cap aliquot
tubes. Freeze and ship frozen.
Serum:
Collect blood in sterile tubes with no anticoagulants; Serum
Separator Tubes (SST(R)s) are recommended. Allow blood to clot at
room temperature and separate serum within 1 hour of collection.
Transfer serum to sterile, plastic, screw-cap aliquot tubes. Freeze
and ship frozen.
Whole Blood:
Collect using standard procedures. Store samples rerfrigerated
following collection. Do not freeze whole blood.
