Interpretation
Positive results suggest 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. If clinical suspicion persists, submit new specimen for retesting in 1 to 2 weeks.
Borderline results may be seen in acute hepatitis E infection with rising level of anti-hepatitis E virus (HEV) IgM, recent hepatitis E infection with declining level of anti-HEV IgM, or cross-reactivity with nonspecific antibodies (ie, false-positive results).
