AxSYM HAVAB 2.0 is a microparticle enzyme immunoassay (MEIA) for the detection of total antibody to hepatitis A Virus (anti-HAV) in human serum or plasma. A test for anti-HAV is indicated as an aid in the diagnosis of previous or ongoing hepatitis A viral infection, or for the detection of anti-HAV after vaccination. 2. The presence of anti- HAV in human serum or plasma is indicative of past or present infection with HepatitisA virus (HAV) or vaccination against HAV Anti-HAV is detectable during the acute stage of illness (IgM anti-HAV) and may persist for years after recovery (IgG anti-HAV).Virus specific IgM anti-HAV is the most reliable marker for determining the acute stage of disease. The test for total anti-HAV is primarily used to determine pervious exposure to HAV. Increasing titres of total anti-HAV in sequential patient samples may indicate an ongoing hepatitis A viral infection. ------------------------------------------------------------------------------------------------------- Done By AXSYM Assay (ABOTT LABORATORIES)
