Why Is This Test Done?

Your healthcare provider may order this test if you have symptoms like fever, fatigue, swollen lymph nodes, or other signs of infection that could be caused by EBV. It’s also used to monitor people with certain immune conditions or cancer treatments that weaken the immune system.

What to Expect Before the Test

No special preparation is needed. You’ll have a small blood draw from a vein, usually in your arm. The blood is sent to a lab for analysis.

What the Test Results Mean

Results are reported as the number of viral copies per milliliter of blood. High levels may indicate an active EBV infection, while lower levels suggest your body is clearing the virus or the infection is resolving.

Common Reasons for Testing

This test is often used in people with chronic fatigue syndrome, lymphoma, or other conditions where EBV is suspected as a contributing factor. It can also help diagnose or manage EBV-related illnesses like infectious mononucleosis.

Clinical interpretation

How abnormal results are interpreted and what conditions they suggest.

Clinical Significance: Active EBV DNA indicates recent or ongoing infection, which may require antiviral treatment or monitoring. Chronic, high levels can be linked to certain cancers or immune disorders, guiding long-term management.
