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 analytical measurement range is 500 to 5 million IU/mL (2.7 to 6.7 log (10) IU/mL). The qualitative limit of detection is 50 IU/mL (1.7 log (10) IU/mL).
Specimens reported as "Detected" but <500 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.
