Abbott Laboratories Introduces Second Fully Automated Test for Hepatitis A Virus


ABBOTT PARK, Ill. -- Abbott Laboratories has introduced its second fully automated hepatitis A test in the United States for its widely-used AxSYM® automated immunoassay instrument system. Used to aid in the laboratory diagnosis of previous or ongoing hepatitis A viral infection, the AxSYM® HAVAB® 2.0 assay detects the total antibody to hepatitis A (anti-HAV) in human serum or plasma. Though primarily used to determine previous exposure to hepatitis A (HAV), the test can also be used to identify HAV-susceptible individuals for vaccination. This introduction marks the completion of Abbott's hepatitis A menu for the AxSYM system in the United States. Abbott will be introducing additional AxSYM tests for other types of hepatitis in the United States throughout 2004 and continuing into 2005.


"As a leader in viral hepatitis testing, Abbott's goal is to provide small, medium and large laboratories with a variety of hepatitis testing options," said Michael J. Collins, vice president, U.S. diagnostic commercial operations, Abbott Laboratories. "The addition of the AxSYM HAVAB test demonstrates our ongoing commitment to completing AxSYM's viral hepatitis panel in the United States. Within a few months, this panel will include the addition of AxSYM® Anti-HCV, a test for hepatitis C. Abbott has also submitted applications to the U.S. Food and Drug Administration (FDA) for its AxSYM hepatitis B tests, which are currently available outside of the United States."


"Our AxSYM HAVAB assay has excellent correlation to Abbott's other well-known hepatitis tests which are run on other systems -- the IMx® HAVAB assay and EIA HAVAB®assay," said William Brown, PhD, vice president, diagnostic assays and systems development, Abbott Laboratories. "Sensitive and specific, the AxSYM HAVAB test also features the added benefit of automation from our AxSYM immunoassay system. This gives laboratories the ability to process a variety of immunodiagnostic tests simultaneously."


In July, Abbott introduced the AxSYM® HAVAB-M 2.0 assay which aids in the diagnosis of an acute or recent hepatitis A viral infection by detecting the IgM antibody to hepatitis A. In most cases, IgM antibody response usually peaks within the first month of illness and persists throughout the first three to six months of infection. According to the World Health Organization (WHO), an estimated 1.5 million clinical cases of hepatitis A occur each year.
