EBV (Infectious Mononucleosis)

What is Epstein-Barr virus?

The Epstein-Barr virus (EBV) is a common virus that is part of the herpesvirus family. It is primarily known as the cause of Infectious Mononucleosis, also called "glandular fever." Most people become infected with this virus at some point in their lives, often at a young age.

Why should you get tested for Epstein-Barr virus?

Testing for the Epstein-Barr virus is useful if you are experiencing symptoms consistent with Infectious Mononucleosis, such as extreme fatigue, fever, swollen lymph nodes, and sore throat. It is also relevant for determining your immune status or confirming that a recent illness was caused by EBV.

What does it indicate?

An EBV test can show whether you have had a recent, active, or past infection. This is usually determined by measuring different types of antibodies against the virus in the blood.

What does a high EBV level mean?

A high level of certain EBV antibodies may indicate an active or recent infection. This can be relevant for patients experiencing symptoms of Infectious Mononucleosis or for individuals with a weakened immune system.

What does a low EBV level mean?

A low level of EBV antibodies, especially in the context of specific antibodies, may indicate a past exposure to the virus without active infection. It can also mean that a person has never been infected with the virus.

• EBV Epstein-Barr virus IgG antibodies (past infection)
• EBV Epstein-Barr virus IgM antibodies (recent infection)
• EBNA Epstein-Barr virus Nuclear Antigen (Epstein-Barr-NA-IgG)
