Important Note

Please note the following interpretations for this test:

Negative Interpretation: No detectable IgM antibodies to HAV were found. A negative result generally indicates that the patient has not been infected. If clinical exposure to HAV is suspected despite a negative finding, a second sample should be collected and tested no less than one to two weeks later.

Equivocal Interpetation: Equivocal samples should be retested in duplicate by the LIAISON HAV IgM assay to confirm the initial result. Samples which are reactive (> 1.10) on both repeat tests should be considered reactive. Samples which are negative (<0.90) on both repeat tests should be considered negative. A second sample should be collected and tested no less than one to two weeks later when at least one of the repeat results is equivocal or if the duplicates of the repeat results are positive and negative.

Positive Interpretation: Indicates the presence of detectable IgM antibodies to HAV. A positive result generally indicates that the paitent has an acute HAV infection. A reactive anti-HAV IgM result does not rule out other hepatitis infections.
