Anti-HAV Total Antibody
Brief Description
The HAVAB-G assay is a chemiluminescence immunoassay (CLIA) for the qualitative detection of IgG antibody to hepatitis A virus (IgG anti-HAV) in human serum from patients with signs and symptoms or at risk for hepatitis. The HAVAB-G assay is used to determine the immune status of individuals to hepatitis A virus infection. A positive HAVAB-G test result will reflex to the HAVAB-M assay. The HAVAB-M assay is a chemiluminescence immunoassay (CLIA) for the qualitative detection of IgM antibody to hepatitis A virus (IgM anti-HAV). A test for IgM anti-HAV is indicated for testing of specimens from individuals who have signs and symptoms consistent with acute hepatitis. Test results are used in conjunction with other laboratory results and clinical information as an aid in the diagnosis of acute or recent Hepatitis A viral infection.
