cobas® TaqScreen MPX Test is the most comprehensive – detects multiple viruses for increased plasma product safety
Roche (SIX: RO, ROG; OTCQX: RHHBY) announced today that the United States Food and Drug Administration (FDA) approved an additional intended use for its licensed nucleic acid test, to screen source plasma in pools comprised of up to 96 individual donations. The test, called the cobas® TaqScreen MPX Test for use on the cobas s 201 system, is a qualitative, in-vitro test for the simultaneous, direct detection of the human immunodeficiency virus (HIV-1 Group M RNA, HIV-1 Group O RNA , HIV-2 RNA), hepatitis C virus RNA and hepatitis B virus DNA in human plasma. The test was approved in the US last year for screening plasma specimens from blood donors and, earlier this year, received the CE Mark for screening source plasma.
Human plasma is fractionated into its components, such as immunoglobulins, albumin, and clotting factors, which have many therapeutic uses. These include treatment of chronic and hereditary diseases and disorders such as hemophilia and primary immunodeficiency diseases. Plasma is also used to treat patients who have suffered severe burns or trauma, and during major surgery.
Many countries have implemented Nucleic Acid Technology (NAT) testing in order to further ensure the safety of blood and blood products. In Western Europe and North America, routine NAT testing, which can detect HIV-1 and HCV in the early stages of infection, has reduced the risk of transfusion-transmitted HIV-1 and HCV infections to negligible levels. The importance of hepatitis B virus in transfusion-transmitted diseases is increasingly being recognized and NAT screening for HBV is being implemented in some countries.
The cobas® TaqScreen MPX Test runs on the fully automated, real-time PCR cobas s 201 system, designed to increase processing efficiency with a unique modular design and ready-to-use reagents.
The cobas s 201 system has the capability of running multiple channels using multi-dye technology, enabling simultaneous detection of several viruses. Roche is developing another multi-dye assay on the same platform, the cobas® TaqScreen DPX test, that is designed to simultaneously provide a quantitative result for B19 virus and a qualitative result for hepatitis A virus.
Roche Diagnostics is the leading provider of real-time PCR-based nucleic acid tests for the international blood bank market. Nucleic acid-based tests enable earlier detection of active HIV, hepatitis C and hepatitis B infections than conventional antibody or antigen assays. Roche assays have been used since 1999 to screen blood and plasma products. Roche launched the automated cobas s 201 system and the cobas® TaqScreen MPX Test outside the United States in 2006 for the most comprehensive single-assay detection of HIV-1 Groups M & O, HIV-2, and hepatitis B and C in donated blood and plasma. The West Nile Virus test for this platform was launched in the US in 2007.
