Hepatitis E Virus (HEV) Antibody IgG

HEPATITIS E VIRUS (HEV) ANTIBODY IGG Test

The Hepatitis E Virus (HEV) Antibody IgG test detects IgG antibodies against the hepatitis E virus (HEV) in the blood. These antibodies generally develop following exposure to HEV and may remain detectable for an extended period.

The test can help determine whether an individual has had previous exposure to hepatitis E. It may be useful when evaluating a history of hepatitis, particularly when symptoms or liver function abnormalities suggest a possible viral cause.

A positive HEV IgG result generally indicates previous exposure or past infection, while it does not by itself confirm an active or recent HEV infection. When acute hepatitis E is suspected, healthcare providers may consider HEV IgM and, when appropriate, HEV RNA testing, along with liver function tests and clinical findings.

Test Recommended for Individuals:

• Individuals being evaluated for previous hepatitis E exposure
• People with unexplained elevation of liver enzymes
• Individuals with symptoms suggestive of viral hepatitis
• People with a history of possible exposure to contaminated food or water
• Individuals being evaluated during a suspected HEV outbreak
• Patients requiring assessment of previous HEV infection
• Individuals advised by their healthcare provider to undergo HEV testing

FAQs

1. What does a positive HEV IgG result mean?
A positive HEV IgG result generally indicates previous exposure to hepatitis E virus. It does not necessarily mean that an active infection is currently present.

2. Can HEV IgG diagnose an acute hepatitis E infection?
No. HEV IgG mainly indicates past exposure. If a recent or acute HEV infection is suspected, HEV IgM and, in selected situations, HEV RNA testing may provide more relevant information.

3. How is HEV IgG different from HEV IgM?
HEV IgM is generally associated with a recent or acute infection, whereas HEV IgG generally develops after exposure and can persist for a longer period. Your healthcare provider will interpret the results alongside symptoms and other liver tests.
