BK VIRUS BY PCR

LAB3241

Collect

All sample types, except blood and urine.  Submit in a sterile container.

Specimen source is required.

If submitting a Pink top tube (EDTA), refer to test code BKPCRPLS.

If submitting a urine sample, refer to test code BKPCRUR.

Pediatric Collection

0.5mL

Unacceptable Conditions

Sample not properly identified; insufficient sample volume; contaminated specimen; clotted sample; gross hemolysis;  non sterile or leaking containers; and samples containing fixatives.

For plasma, refer to test code BKPCRPLS. For urine, refer to test code BKPCRUR.

Storage/Transport Temperature

Internal: Deliver to lab immediately.
Offsite: Send at 2-8 degrees C if delivery is less than 72 hours. If delivery is not expected within 72 hours, freeze at -70 degrees C and ship on dry ice.

Stability (from collection to initiation)

Ambient: 12 hours; Refrigerated: 72 hours; Frozen (-70 degrees C): 6 months

Remarks

Qualitative results will be given for tissues, stools, swabs, or diluted samples. Quantitative results will be given for undiluted fluids such as bronchial fluid, amniotic fluid, etc.

Performed by

PCL Clinical Laboratory - Molecular Diagnostics

Performed

Mon - Fri

Methodology

DNA amplification by polymerase chain reaction (PCR) using a BK-specific DNA probe detected by real-time PCR.

Reported

24-48 hours

Synonyms

  • LAB3241

Interpretive Data

Qualitative testing:

TND = Target Not Detected (negative)

Positive = Virus Detected

Quantitative testing:

TND = Target Not Detected (negative)

POS<1000 = Positive. Virus detected below 1000 copies/mL

1001 - 65,000,000 copies/mL = Quantitative range

>65,000,000 copies/mL = Greater than maximum quantitative range
