Who Should Get This Test
To quantify BK virus DNA levels for diagnosis and monitoring of BK virus-associated nephropathy in immunocompromised patients, especially kidney transplant recipients.
How to Prepare
- Use 3 ml (2 ml min) plasma from 1 Lavender Top (EDTA) tube
- OR 15 ml (5 mL min.) random urine in a sterile screw capped container
- Ship refrigerated or frozen
- Ensure samples are properly labeled with patient details
Doctor's Notes
Reviewed by Dr Ramarao Paidisetty — MBBS, MD (Biochemistry) · Reg. No. 21504
"Regular monitoring of BK virus levels is crucial for kidney transplant recipients to prevent nephropathy and graft failure. Early detection allows timely adjustment of immunosuppressive therapy."

Test Parameters & Specifications
Sample Stability
- Improperly labeled or unlabeled samples
- Insufficient sample volume
- Hemolyzed or contaminated samples
- Samples not stored or transported correctly
Understanding Your Results
Positive (High Viral Load)
Indicates presence of BK virus DNA; may suggest active infection or BKVAN. Clinical correlation and further evaluation needed.
Negative (Not Detected)
No BK virus DNA detected. However, if symptoms persist, repeat testing or alternative diagnostics may be considered.
Low Viral Load
May indicate early infection or monitoring of treatment response. Consult with nephrologist for management.
If you experience symptoms such as flank pain, fever, blood in urine, or have risk factors like kidney transplant or immunosuppression, consult a nephrologist promptly.
Limitations
- ⚠False negatives possible if viral load is very low
- ⚠Quantitative results may vary between labs due to assay differences
- ⚠Does not differentiate between active infection and latent virus
- ⚠Must be interpreted alongside clinical findings
Risks & Considerations
- ●Minimal risks from blood draw: bruising, soreness, rare infection
- ●Urine collection: no significant risks
- ●False results possible, requiring retest
Interfering Factors
- ●Sample contamination
- ●Hemolyzed or lipemic samples
- ●Improper sample storage or transport
- ●Low viral load below detection limit

|---|---|---|---|---|---|
| Comparison | BK Virus PCR Quantitative Test | Invasive but gold standard for diagnosing BKVAN; BK PCR is non-invasive and quantitative. | Detects decoy cells but less specific; BK PCR provides viral load quantification. | Measures kidney function but not specific for BK virus; used alongside BK PCR. | Detects cytomegalovirus; often ordered together in transplant monitoring. |
