Test Overview
Test Methodology

EIA

Test Usage

Diagnosis of acute or recent (<6 months) hepatitis E infection.

Reference Range *

Negative. Borderline results may be seen in: 1) acute hepatitis E infection with rising level of anti-hepatitis E virus (HEV) IgM; 2) recent hepatitis E infection with declining level of anti-HEV IgM; or 3) cross-reactivity with nonspecific antibodies (ie, false-positive results).

* 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, especially in immunocompromised patients. Repeat testing of serum for anti-HEV IgM in 2 to 4 weeks may be necessary for diagnosis of acute in such patients.
