Methodology
This test uses the polymerase chain reaction to amplify regions of the Epstein Barr Virus BLLF1
gene. Real-time detection and quantification are used to determine the viral concentration. The
qualitative limit of detection is 20 IU/mL (1.3 log (10) IU/mL).
Specimens reported as "Detected" but <50 IU/mL, contain detectable levels of EB Virus DNA,
but the viral load is below the limit of quantification. A "Not Detected" result does not rule out infection.
