Method Description

Testing is performed using a combination of MGB Alert EBV Primer and Probe ASRs (ELITechGroup Molecular Diagnostics, Inc.) and 2x MGB Alert PCR Master Mix with the Abbott m2000 RealTime System (Abbott Molecular, Inc.). The MGB Alert reagents are designed based on minor groove-binding Pleiades probe chemistry. This assay amplifies the p140 region of the BNRF1 gene of Epstein-Barr virus (EBV) for detection and quantification of EBV DNA in human plasma.

 

The Abbott mSample Preparation System kit is used with the automated Abbott m2000sp sample preparation system to extract and purify viral DNA from human plasma specimens, based on magnetic particle technology. An internal control template is introduced into each specimen during sample preparation to assess extraction failure or inhibition during the sample preparation and qPCR processes, respectively. Amplification and detection of target sequence is performed on the Abbott m2000rt instrument. The assay is calibrated to the First World Health Organization International Standard for EBV, NIBSC code: 09/260 by using commercially available EBV verification panels consisting of multiple panel members calibrated to the WHO standard and with EBV DNA levels ranging over 4 log IU/mL.(Unpublished Mayo method)
