Anti-Hepatitis E Virus IgG Antibody (Serum)

What Does This Test Measure?

The test detects IgG antibodies specific to Hepatitis E virus. These antibodies develop after your immune system has encountered the virus, often within weeks to months after infection. They can remain in your blood for a long time, even after the acute infection has resolved.

Why Might You Need This Test?

Your healthcare provider may recommend this test if you have symptoms like fever, nausea, abdominal pain, or jaundice—common signs of Hepatitis E—but no clear cause. It may also be used in travelers to high-risk regions, individuals with chronic liver disease, or those with unexplained liver enzyme abnormalities.

What to Expect Before the Test

No special preparation is needed. You’ll have a small needle inserted into your arm to draw blood. The process usually takes a few minutes. If you’re pregnant, have a bleeding disorder, or take blood-thinning medications, let your provider know beforehand.

What to Expect After the Test

After the blood draw, you may feel slight discomfort or bruising at the site, which should resolve quickly. Apply gentle pressure to the area to help reduce any swelling. Avoid vigorous activity for a short time to prevent excessive bleeding.
