Rapid qualitative detection of Epstein-Barr virus (EBV) DNA in specimens

 

Diagnosis of disease due to EBV

 

This test should not be used to screen asymptomatic patients.

Clinical Information
Discusses physiology, pathophysiology, and general clinical aspects, as they relate to a laboratory test

Epstein-Barr virus (EBV) is the causative agent of infectious mononucleosis, Burkitt lymphoma, and in Southern China, nasopharyngeal carcinoma. EBV-associated central nervous system (CNS) disease is most commonly associated with primary CNS lymphoma in patients with AIDS. In addition, CNS infection associated with the detection of EBV DNA can be seen in immunocompetent patients.

Reference Values
Describes reference intervals and additional information for interpretation of test results. May include intervals based on age and sex when appropriate. Intervals are Mayo-derived, unless otherwise designated. If an interpretive report is provided, the reference value field will state this.

Negative

Interpretation
Provides information to assist in interpretation of the test results

Detection of Epstein-Barr virus (EBV) DNA in cerebrospinal fluid (CSF) supports the clinical diagnosis of central nervous system (CNS) disease due to the virus. EBV DNA is not detected in CSF from patients without CNS disease caused by this virus.

Cautions
Discusses conditions that may cause diagnostic confusion, including improper specimen collection and handling, inappropriate test selection, and interfering substances

A negative result does not eliminate the possibility of Epstein-Barr virus (EBV) infection of the central nervous system.

 

This assay may detect viremia or viral shedding in asymptomatic individuals. However, this assay is only to be used for patients with a clinical history and symptoms consistent with EBV infection and must be interpreted in the context of the clinical picture.

Supportive Data

Thirty negative specimens of each matrix accepted for this assay were spiked with Epstein-Barr positive control plasmid at the approximate limit of detection (10-20 targets/mcL). The 30 spiked specimens of each type were run in a blinded manner along with 30 negative (nonspiked) specimens; 93% to 100% of the spiked specimens were positive and 100% of the nonspiked specimens were negative.

 

Analytical Sensitivity/Limit of Detection:

The 95% limit of detection (LOD) for this assay is less than 10 targets per microliter using plasmid and whole virus spiked into matrix. The LOD was confirmed in each matrix type that is accepted for testing with this assay.

 

Analytical Specificity:

No polymerase chain reaction (PCR) signal was obtained from extracts of 40 bacterial and viral isolates that could cause similar symptoms including herpes simplex virus (HSV) 1 and 2; cytomegalovirus (CMV); varicella zoster virus (VZV); and human herpesvirus (HHV) 6, HHV 7, and HHV 8.

 

Precision:

Interassay precision was 100% and intraassay precision was 100%. 

 

Reportable Range:

This is a qualitative assay and results are reported as either negative or positive for targeted Epstein-Barr virus DNA.

Method Description
Describes how the test is performed and provides a method-specific reference

Viral nucleic acid is extracted by the MagNA Pure automated instrument (Roche Applied Science) from clinical specimens. Primers are directed to the target gene (latent membrane protein). The LightCycler instrument amplifies and monitors by fluorescence the development of target nucleic acid sequences after the annealing step during polymerase chain reaction (PCR) cycling. This is an automated PCR system that can rapidly detect (30-40 minutes) amplicon development through stringent air-controlled temperature cycling in capillary cuvettes. The detection of amplified products is based on the fluorescence resonance energy transfer (FRET) principle. For FRET product detection, a hybridization probe with a donor fluorophore, fluorescein, on the 3' end is excited by an external light source and emits light that is absorbed by a second hybridization probe with an acceptor fluorophore, LC-Red 640, at the 5' end. The acceptor fluorophore then emits a light of a different wavelength that can be measured with a signal that is proportional to the amount of specific PCR product. Melting curve analysis is performed following PCR amplification. Starting at 45 degrees C, the temperature in the thermal chamber is slowly raised to 80 degrees C and the fluorescence is measured at frequent intervals. Analysis of the PCR amplification and probe melting curves is accomplished through the use of LightCycler software.(Espy MJ, Patel R, Paya C, Smith TF: Quantification of Epstein-Barr virus viral load in transplant patients by LightCycler PCR.
