The Hepatitis E Virus (HEV) IgG test offers a glimpse into your body’s past encounters with HEV. It detects IgG antibodies, the “memory markers” your immune system produces after exposure to the virus. A positive result doesn’t mean you are currently infected—it shows that your body has fought off HEV before. This is particularly useful for understanding past infections, assessing immunity, and monitoring liver health over time. A simple blood sample provides your doctor with this important historical insight, helping guide preventive care, lifestyle advice, and follow-up decisions to keep your liver healthy and protected for the future.
