The TaqScreen MPX Test detects three types of HIV: HIV-1 Group M RNA, HIV-1 Group O RNA, and HIV-2 RNA.
FDA sanctioned Roche Molecular Diagnostics’ cobas TaqScreen MPX Test that screens for three types of HIV as well as HCV and HBV in donated blood plasma and tissue. It is a qualitative nucleic acid in vitro test for comprehensive single-assay detection of HIV-1 Group M RNA, HIV-1 Group O RNA, HIV-2 RNA, HCV RNA, and HBV DNA.
HIV-2 infections and HIV-1 Group O infections are predominantly found on the African continent. Some cases of infection with these two types of viruses have also been detected in the U.S.
The MPX test is designed for use with plasma specimens from human donors of whole blood and blood components but not for testing donated source plasma. It is also intended for screening tissue specimens obtained while the donor’s heart is still beating. The assay is not intended for use on specimens from donors whose heart no longer functions or as a diagnostic aid.
The cobas TaqScreen MPX Test runs on the fully automated cobas s 201 System.
