What Is This Test Measuring?

Epstein-Barr virus (EBV) is a common virus that can cause infections like mononucleosis. This test looks for tiny pieces of the virus’s genetic material (DNA) in your blood. If the DNA is present, it suggests you’re actively infected with EBV.

Why Might Your Doctor Order This Test?

Your doctor may recommend this test if you have symptoms like fever, fatigue, swollen lymph nodes, or sore throat that could be linked to EBV. It’s also used to monitor people with certain immune conditions or cancers linked to EBV, such as lymphoma.

How Is the Test Performed?

A blood sample is drawn from a vein, usually in your arm. The sample is then sent to a lab where the virus’s DNA is detected and measured using advanced techniques like polymerase chain reaction (PCR).

What Do the Results Mean?

Results are typically reported as a count of viral DNA copies per milliliter of blood. Higher counts often mean a more active infection, while lower or undetectable levels may suggest recovery or a less active infection.

Clinical interpretation

How abnormal results are interpreted and what conditions they suggest.
