  1. Consensus log10 virus concentrations were calculated as the mean values reported from positives datasets (n) submitted by clinical laboratories
  2. ND, EBV DNA was not detected
  3. Pos NQ, EBV DNA was detected but not quantified
  4. C core, E educational
  5. Excluded, panel member was excluded of the QCMD report
  6. delta log10, log10 copies/ml difference between the RT assay and QCMD consensus
