Hepatitis A Virus Antibodies (Total)
Also known as: HAVAB
Use
The Hepatitis A Virus Antibodies (Total) test is primarily used to assess immunity to Hepatitis A virus (HAV). It detects both IgG and IgM antibodies but does not differentiate between them. This test is not generally recommended for diagnosing acute HAV infection but can be helpful in evaluating immunization status and determining past exposure to the virus.
Special Instructions
Not provided.
Limitations
The assay does not differentiate between IgG and IgM antibodies. Specimens collected in citrate-based anticoagulants, those containing particulate material, or those that are heat-inactivated, severely hemolyzed, or lipemic are unacceptable. False positive results can occur. Repeated freeze/thaw cycles of specimens should be avoided.
