Test is based on innovative dual-target approach.
Roche (SIX: RO, ROG; OTCQX: RHHBY) announced today that a new HIV viral load test has been approved by the United States Food and Drug Administration (FDA) and will be commercially available in the US later this year. Like other innovative Roche HIV tests, this one targets two highly conserved regions of the HIV-1 genome and avoids any regions which are current drug targets, thus providing increased reliability as compared to other single target assays should a mutation occur.
“The approval of the Roche HIV test expands the availability to more laboratories, clinicians and patients,” said Paul Brown, PhD, Head of Roche Molecular Diagnostics. “Roche is committed todeveloping new diagnostic tools such as this highly innovative HIV ‘dual target’ test to helpimprove the ability of physicians to monitor viral load and properly treat people living with HIV.”
About this test
The COBAS® TaqMan® HIV-1 Test, v2.0 utilizes the FDA-approved High Pure System Viral Nucleic Acid Kit for manual specimen preparation and the COBAS® TaqMan® 48 Analyzer for automated amplification and detection.
About the dual-target test approach
Roche’s dual-target approach for HIV viral load testing ensures enhanced reliability of results and increased confidence in assessing viral loads even in the face of the rapidly growing genetic diversity of HIV-1.1,2This approach targets two highly conserved regions of the HIV-1 genome and avoids any regions which are current drug targets, thus providing reliable test results even with rare mismatches in primer/probe binding sites and when mutations are present. Since Roche first introduced this innovative dual-target approach for monitoring HIV-1 patients on antiretroviral therapy in 2008, over eight million tests have been performed worldwide on Roche fully automated real-time PCR platforms.
According to the Centers for Disease Control and Prevention (CDC), an estimated 1.2 million persons were living with HIV infection in the United States at the end of 2010. Of those, 20% had undiagnosed HIV infections.3 Highly active antiretroviral treatment (HAART) and viral load tests that determine the amount of circulating HIV have contributed to a profound increase in life expectancy for people living with HIV.4
