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

Non-reactive

 

Borderline

 

Reactive
 

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.
