Clinical Significance

Monitoring EBV DNA levels by quantitative PCR in patients at risk of EBV-associated lymphoproliferative disorders may allow timely recognition of virus reactivation and permit installment of antiviral treatment. This is a quantitative molecular test, with a linear range of 200-2,000,000 copies/mL.

Reference Range

EBV DNA, QN PCR: <200 copies/mL

EBV DNA, QN PCR: <2.30 Log copies/mL

Rejection Due To
