The quantitative range of this assay is 2.6-7.6 log copies/mL (390-39,000,000 copies/mL).
A negative result, less than 2.6 log copies/mL or less than 390 copies/mL, does not rule out the presence of PCR inhibitors in the patient specimen or EBV DNA nucleic acid in concentrations below the level of detection of the assay. Inhibition may also lead to underestimation of viral quantitation.
