BK Virus Load (Quantitative) by RT-PCR, Plasma

Test Overview

The BK Virus Load Quantitative by RT-PCR test measures the amount of BK virus (BKV) DNA present in plasma (blood) using Real-Time Polymerase Chain Reaction (RT-PCR) technology.

BK virus commonly remains inactive in healthy individuals but can reactivate in people with weakened immune systems, especially:

• Kidney transplant recipients
• Bone marrow transplant patients
• Immunocompromised individuals

Why This Test is Done

• Detect BK virus infection or reactivation
• Monitor viral load in transplant patients
• Assess risk of BK virus-associated nephropathy
• Monitor response to treatment or immunosuppressive therapy adjustment

Sample Required

• Sample Type: Plasma (Blood)
• Method: RT-PCR (Quantitative)

Symptoms Associated with BK Virus Reactivation

• Reduced kidney function
• Painful urination
• Blood in urine
• Fever
• Fatigue

Interpretation

• Not Detected: No measurable BK virus DNA
• Low Viral Load: Early or mild infection/reactivation
• High Viral Load: Significant viral replication; may require medical intervention

Preparation

• No special preparation required unless advised by your doctor.

Turnaround Time

• Usually 24–72 hours depending on laboratory processing.

Recommended For

• Kidney transplant recipients
• Immunocompromised patients
• Patients with unexplained kidney dysfunction
