Abbott has received approval from the US Food and Drug Administration for its Abbott Prism hepatitis B surface antigen (HBsAg) and its Prism HBsAg Confirmatory test. These tests can be used by laboratory technicians to screen donated blood for HBsAg.

Used in more than 30 countries, the Prism system was recently approved for use in the United States with its first hepatitis B test, Prism HBcore, introduced in October. Additional hepatitis and retrovirus screening tests are currently under FDA review.
"We continue to focus on expanding our automated hepatitis testing menus across all of our diagnostic platforms," said Don Patton, vice president, global diagnostic commercial operations, Abbott. "We also will continue to leverage our scientific expertise and understanding of viral hepatitis in introducing new diagnostic tests to support laboratory needs in infectious disease testing."

Abbott is a leader in ensuring the safety of the world's blood supply. In 1985, Abbott developed the first HIV blood-screening test approved in the United States. Abbott's hepatitis tests are used thousands of times every day around the globe for blood screening and diagnostic testing.

According to the American Association of Blood Banks (AABB), eight million volunteers donate about 15 million units of whole blood each year. Each donated unit of blood is tested for infectious diseases including hepatitis, HIV and other retroviruses.

The Prism instrument consolidates testing into a single system, automating many of the manual testing procedures and steps currently used to screen blood. Safety features built into the system help track and monitor each sample throughout the testing process providing documentation and quality control for testing facilities. The Prism system can run 160 samples per hour, making it possible to test more than 1,200 samples per eight-hour shift.
