What Is Epstein-Barr Virus (EBV)?

Epstein-Barr virus (EBV) is a common virus that can cause infections like mononucleosis (infectious mononucleosis). It’s often spread through saliva and can affect the immune system. While most people recover without complications, some may experience long-term issues or develop conditions like certain cancers or autoimmune disorders.

Why Might You Need This Test?

Your healthcare provider may order this test if you have symptoms of EBV infection (e.g., fever, fatigue, swollen lymph nodes) or if you’re at higher risk (e.g., immunocompromised due to medication, HIV, or cancer treatment). It can also help monitor how your body is responding to treatment.

How Is the Test Performed?

A blood sample is taken from a vein in your arm. The lab then analyzes the DNA from your blood to detect EBV. Results are typically reported as a concentration of EBV DNA, which can vary widely depending on infection stage and immune response.

What Do the Results Mean?

High levels of EBV DNA often indicate an active infection, while lower levels may suggest your body is clearing the virus. Very high levels could mean severe illness or complications. Your doctor will interpret results in the context of your symptoms and medical history.
