Critical Results


Test Limitations

This test can be used to determine if a patient has or recently had an acute or asymptomatic hepatitis A infection. This test does not measure anti-HAV IgG and therefore cannot be used to determine a patient’s immune status to hepatitis A.

Assay performance characteristics have not been established for immunocompromised, immunosuppressed, infants, children, or adolescent patients.

Reference Range






The results from this or any other diagnostic kit should be used and interpreted only in the context of the overall clinical picture.  A negative test result does not exclude the possibility of exposure to hepatitis A virus.
