About this service

The Epstein-Barr Virus IgG test is a blood test used to measure the levels of IgG antibodies directed against the Epstein-Barr virus. This test helps determine whether an individual has been exposed to the virus in the past, which assists in evaluating their immune status. The Epstein-Barr virus is responsible for several diseases, including infectious mononucleosis. By measuring antibody levels, doctors can provide insights into the history of the infection and guide appropriate treatment options if necessary.

Purpose Test

This test can help in:
Confirming infection history: Determines whether the person has had mononucleosis or any other condition associated with the virus.
Assessing immunity: Understands whether the person has immunity against the virus.
Distinguishing between current and past infection: Helps clarify whether current symptoms are related to a new infection or an immune response to a previous virus exposure.

Recommended groups

Individuals with infection symptoms: Such as fever, extreme fatigue, sore throat, and swollen lymph nodes, which may indicate mononucleosis.
People who have been in contact with an infected person: To determine whether they have been exposed to the virus previously.
Individuals with immune-related diseases: To monitor immune system response and ensure immunity against the virus.
Pregnant women: To assess immune status and avoid potential complications.
People with a family history of virus-related diseases: To evaluate risks and assist in treatment planning if necessary.

Symptoms indicative

Severe fatigue: Persistent exhaustion and inability to perform daily activities.
Fever: Unexplained increase in body temperature.
Sore throat: Severe throat pain, possibly accompanied by difficulty swallowing.
Swollen lymph nodes: Especially in the neck or jaw area.
Muscle aches: Generalized body pain.
Skin rash: Appearance of an unexplained rash.
Loss of appetite: Reduced desire to eat.
Headache: Frequent or severe headaches.

Normal Levels

Negative result: No IgG antibodies are present, meaning the person has not been exposed to the virus or has not yet developed antibodies.
Positive result: Indicates the presence of IgG antibodies, meaning the person has been exposed to the virus in the past.
Typical reference values: Negative: Less than 18-20 U/mL (may vary by laboratory).
Positive: 20 U/mL or higher.
