||
Geisinger Epic Procedure Code: LAB3542
Geisinger Epic ID: 121985
|
||
SPECIMEN COLLECTION |
||
Specimen type: |
EDTA whole blood, EDTA plasma, Serum | |
Preferred collection container: |
||
Alternate Collection Container: |
3.5 mL gold-top (serum separator) tube
|
|
Specimen required: |
0.7 mL (minimum 0.3 mL) EDTA whole blood, EDTA plasma, or serum | |
Special notes: |
Whole Blood: Collect blood in tube containing EDTA. Store samples refrigerated following collection. Do not freeze whole blood. Plasma: Collect blood in sterile tubes containing EDTA as an anticoagulant. 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 are recommended. Allow blood to clot at room temperature and separate serum within 1 hour of collection. Transfer serum to aliquot tube, freeze and ship frozen. | |

Clinical significance: |
BK Virus DNA, Quantitative Real-Time PCR, Plasma - 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. | |
