Description:
This test looks for antibodies to Hepatitis E (HEV). Hep E is a liver infection caused by the Hepatitis E virus. HEV is found in the stool of an infected person. The most common means of contracting Hep E is by drinking contaminated water or eating food that is prepared by someone who has not properly washed their hands. Hep E can also infect animals so eating undercooked meat can also pose a risk of infection. HEV is rare in the United States and most cases occur in countries with a lack of widespread water purification or access to proper sanitation, hygiene, and healthcare. It is not unusual for someone who is exposed to Hep E to display no symptoms. When symptoms do occur they can include fatigue, poor appetite, stomach pain, nausea, dark-colored urine, and jaundice. Most people with Hepatitis E infections recover on their own with no serious health complications. However, young children, pregnant women, and people with weakened immune systems may develop a more serious illness. In rare cases, Hepatitis E can lead to severe liver failure and death. There is currently no vaccine available for Hep E.
This test looks for both IgM and IgG antibodies. IgM antibodies begin to develop shortly after infection and then begin to fade out after several months. IgG antibodies begin to develop a bit later and can persist even after a person has recovered. IgG antibodies can provide protection from further infection but it is currently unclear how long this immunity will last.
Hepatitis E antibody testing is usually ordered for someone who has recently traveled to an area where HEV is prevalent and is displaying symptoms of viral hepatitis, especially if they have already tested negative for other types of hepatitis such as Hep A, Hep B, or Hep C. Please see our Hepatitis Testing Category for more options.
Turnaround for this test is typically 3-8 business days.

Detection Period:
IgM antibodies are typically detectable beginning 1-4 weeks after infection. IgG antibodies are typically detectable within 4-6 weeks of infection.
