- Epstein-Barr Virus (EBV), Quantitative, DNA by Real-time PCR
Expected Turnaround Time
2 - 4 days
Turnaround time is defined as the usual number of days from the date of pickup of a specimen for testing to when the result is released to the ordering provider. In some cases, additional time should be allowed for additional confirmatory or additional reflex tests. Testing schedules may vary.

Specimen Requirements
Specimen
Plasma (EDTA)
Volume
1 mL
Minimum Volume
0.5 mL (Note: This volume does not allow for repeat testing.)
Container
Plasma from a lavender-top tube. Ship in a screw-cap polypropylene frozen transport tube.
Collection
Collect specimen in lavender-top (EDTA) tube. Centrifuge specimen within 24 hours of collection. Remove plasma, transfer plasma to a screw-cap polypropylene transport tube, and freeze. Ship frozen (preferred). To avoid delays in turnaround time when requesting multiple tests on frozen samples, please submit separate frozen specimens for each test requested.

Causes for Rejection
Quantity not sufficient for analysis; gross specimen contamination; specimen too old; leaking or broken tube
Test Details
Use
This assay is intended to be used for the quantitative detection of Epstein-Barr virus (EBV) DNA and as an aid in the diagnosis and management of EBV infections. This assay is traceable to the 1st WHO International Standard for Epstein Barr Virus for Nucleic Acid Amplification Techniques (NAT)-based assays.
Limitations
The quantitative range is 35.0 IU/mL to 100,000,000 IU/mL, and the analytical sensitivity is 18.8 IU/mL.
Methodology
Real-time polymerase chain reaction (PCR)
