Hepatitis E virus (HEV) causes an acute, usually self-limited infection. This small, nonenveloped RNA virus is from animal reservoirs (eg, hogs) and is transmitted to humans via the fecal-oral route.
HEV (IgM) test is useful for confirmation of reactive hepatitis E virus IgM antibody screening test results for the diagnosis of acute or recent (<6 months) hepatitis E infection.
Positive results confirm the presence of acute or recent (in the preceding 6 months) hepatitis E infection.
Negative results indicate absence of acute or recent hepatitis E infection.
