Epstein-Barr Virus DNA, Quantitative, Real-Time PCR (Plasma) Test
This test measures the amount of Epstein-Barr virus (EBV) DNA present in a plasma sample, using real-time polymerase chain reaction (PCR) technology. It reports a quantitative viral DNA result rather than a simple positive or negative.
About this test
The test quantifies Epstein-Barr virus DNA in plasma using real-time PCR, a method that amplifies and measures viral genetic material in the sample. Because the result is quantitative, it is used to track the amount of EBV DNA present, which a clinician reads in context, such as in post-transplant monitoring or evaluation of lymphoproliferative concerns, rather than as a stand-alone diagnosis.
Quest lists this product under names that include Post Transplant, PTLD, Lymphoproliferative and Infectious Mononucleosis, reflecting the settings where a quantitative EBV DNA level is often reviewed. Because it is a quantitative measurement rather than a positive/negative result, a change in the level over time, read by a clinician, can matter as much as any single value.

Additional details
What this test looks at
The test reports the quantity of Epstein-Barr virus DNA present in a plasma sample, measured by real-time PCR. A single value describes viral DNA load at one point in time, and a clinician reads it alongside a person's clinical history.

Laboratory results should always be interpreted by a licensed clinician who knows your health history. This page is information about a test, not medical advice.
Frequently asked questions
What does this test measure?
It measures the quantity of Epstein-Barr virus DNA present in a plasma sample, using real-time PCR technology.
How is the sample collected?
The test uses a plasma sample from a routine blood draw, analyzed using real-time polymerase chain reaction.
Do I need to prepare for this test?
No preparation instructions are listed for this test, though people follow any instructions their ordering clinician provides.
Is this the same as an EBV antibody test?
No. This test measures the amount of EBV DNA directly, using PCR, rather than measuring antibodies the body has made in response to the virus.
