Polyomavirus Polymerase Chain Reaction as a Surrogate Marker of Polyomavirus-Associated Nephropathy

Abstract

BKV PCR may be a clinically useful noninvasive test to identify renal recipients with concurrent PVAN. BKV DNA >1.6E+04 copies/mL of plasma and >2.5E+07 copies/mL of urine were highly associated with concurrent PVAN whereas a negative PCR test makes the diagnosis of PVAN highly unlikely.
