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. Reportable Range is 35.0-100,000,000 IU/mL (1.54-8.00 log IU/mL).
