Clinical Info
The test is used to determine the immune status to Hepatitis A Virus (HAV) as a result of vaccination or past infection. Should recent infection be suspected, this test needs to be ordered along with HAV IgM test.
Clinical Limitation
Serum is the only acceptable sample type. Performance has not been established for the use of cadaveric specimens or other body fluids. Do not use specimens with the following conditions: heat-inactivated, grossly hemolyzed or obvious microbial contamination. This assay has not been FDA cleared or approved for the screening of blood or plasma donors. This assay cannot be used for the diagnosis of acute HAV infection. Specimens from individuals with anti-E. coli, anti-CMV, or hemodialysis patients may cross-react with this assay.
