Test Overview

Test Methodology

EIA

Test Usage

Diagnosis of past exposure to hepatitis E virus.

Reference Range*

Negative. Borderline results may be seen in: 1) acute or recent hepatitis E infection with rising level of anti-HEV IgG, or 2) cross-reactivity with nonspecific antibodies (ie, false-positive results). Repeat testing of serum for anti-HEV IgG in 4 to 6 weeks is recommended to determine the definitive HEV infection status.

* Reference ranges may change over time. Please refer to the original patient report when evaluating results.

Test Limitations

A negative test result does not exclude the presence of recent hepatitis E infection (<2 month duration), especially in immunocompromised patients. Repeat testing for anti-hepatitis E virus (HEV) IgM and anti-HEV IgG in 1 to 2 months is necessary for diagnosis of recent hepatitis E.
