HERCULES, CA--(Marketwire - 07/25/11) - Bio-Rad Laboratories, Inc. (NYSE:BIO - News) and (NYSE:BIO.B - News), a multinational manufacturer and distributor of life science research and clinical diagnostic products, today announced that it has received Premarket Application approval from the U.S. Food and Drug Administration for Bio-Rad's fourth-generation HIV assay, the GS HIV Combo Ag/Ab EIA (enzyme immunoassay).

The GS HIV Combo Ag/Ab EIA detects HIV antigens (proteins that are part of the HIV virus) and HIV antibodies (proteins that are produced by the body to fight the HIV infection), offering early detection of HIV infections, including acute HIV infections. Clinical studies were performed at five major institutions in the United States on a large sample population including adult and pediatric patients in high and low risk populations.

According to the most recent information published by the U.S. Centers for Disease Control, "more than one million people are living with HIV in the United States. One in five (21%) of those people living with HIV is unaware of their infection. An estimated 56,300 Americans become infected with HIV each year." Early detection of HIV leads to early treatment and helps prevent new infections of the virus.

"Bio-Rad is pleased to offer its fourth-generation HIV assay in the U.S.," said John Goetz, Bio-Rad Vice President and Group Manager of Clinical Diagnostics. "Detecting HIV antigens and HIV antibodies in the same test provides clinicians with the ability to detect the virus at an earlier stage. This results in faster diagnosis of HIV-infected individuals so they are able to get the treatment they need more quickly. Bio-Rad has a long history of providing laboratories the tools that they need for HIV detection. We will continue to remain in the forefront of this critical area."

About the GS HIV Combo Ag/Ab EIA Assay
The GS HIV Combo Ag/Ab EIA is an enzyme immunoassay kit for the simultaneous qualitative detection of Human Immunodeficiency Virus (HIV) p24 antigen and antibodies to HIV Type 1 (HIV-1 groups M and O) and HIV Type 2 (HIV-2) in human serum or plasma. The kit is intended to be used as an aid in the diagnosis of infection of HIV-1 and/or HIV-2 in adults and children as young as two years of age. The kit can run on Bio-Rad's EVOLIS™ system, a self-contained automated microplate processor, and the kits may also be used with manual testing systems.
