Stay one step ahead. It takes more than just a single target.
As the challenges you face evolve, stay one step ahead with the next generation quantitative HIV-1 assay with a dual target approach.
Rapidly mutating HIV-1 virus can evade quantification with a single target viral load assay. cobas® HIV-1 quantitative nucleic acid test for use on the cobas® 5800/6800/8800 Systems targets two unique regions of the HIV-1 genome, gag and LTR, which are not subject to selective drug pressure. This approach improves test sensitivity, coverage and security in the event of mutation in one primer/probe region.
Features and Benefits
Targeting two regions improves genotype inclusivity, detects HIV-1 variants and potentially avoids under quantification.
Accurate quantification of HIV-1 RNA with a dual target assay contributes to optimal treatment decisions for patient management.
Intended Use
cobas® HIV-1 is an in vitro nucleic acid amplification test for the quantitation of HIV-1 in EDTA plasma of HIV-1-infected individuals. This test is intended for use in conjunction with clinical presentation and other laboratory markers for the clinical management of HIV-1-infected patients. This test can be used for confirmation of HIV-1 infection in antibody reactive individuals and to assess patient prognosis by measuring the baseline HIV-1 level or to monitor the effects of antiretroviral therapy by measuring changes in HIV-1 RNA levels during the course of antiretroviral treatment.
cobas® HIV-1/HIV-2 Qualitative Test is the only multiplex, real-time PCR test that offers immediate virus discrimination between HIV-1 and HIV-2 in a single test while providing dual target technology for HIV-1 testing.
Why is the distinction between HIV-1 and HIV-2 important?
HIV-2 appears less virulent and may show a slower progression to opportunistic infections
HIV-2 viral loads may be incorrectly quantified by HIV-1 viral load tests
Some HIV-1 medications are not effective against HIV-2
Co-infection with both HIV-1 and HIV-2 can complicate viral load monitoring and antiretroviral treatment
Confidently diagnose HIV positive patients as early as possible
cobas® HIV-1/HIV-2 Qualitative Test is the first automated nucleic acid test to differentiate HIV subtypes and to enable accurate diagnosis of HIV positive patients.
Intended Use
cobas® HIV-1/HIV-2 Qualitative for use on the cobas® 5800/6800/8800 Systems is an in vitro nucleic acid amplification test for the qualitative detection and differentiation of human immunodeficiency virus type 1 (HIV-1) and type 2 (HIV-2) RNA in human serum and plasma.
The test is intended to be used as an aid in diagnosis of HIV-1/HIV-2 infection. The cobas® HIV-1/HIV-2 Qualitative may also be used as an additional test to confirm the presence of HIV-1 or HIV-2 infection in an individual with specimens reactive for HIV-1 or HIV-2 antibodies or antigens. The assay may also be used as an aid in the diagnosis of infection with HIV-1 and/or HIV-2 in pediatric subjects and pregnant women.
This assay is not intended to be used for monitoring patient status, or for screening donors of blood, plasma, or human cells, tissues, and cellular and tissue-based products (HCT/Ps) for HIV.
See what truly matters
cobas® HCV, quantitative nucleic acid test for use on the cobas® 5800/6800/8000 systems, delivers robust, clinically relevant assay performance based on the proprietary dual-probe assay design from Roche with built-in redundancy for broad genotype coverage and improved mismatch tolerance to ensure confidence in viral load monitoring. cobas® HCV is designed to deliver high sensitivity to meet the requirements of current and future chronic hepatitis C therapies combined with an efficient workflow for laboratories.
Features and Benefits
HCV – an ever-changing virus
The combination of error-prone RNA replication with a high rate of virus production results in extreme genetic variability of hepatitis C virus (HCV). A quantitative HCV RNA test must therefore be able to tolerate sequence mismatches for accurate and reliable results.
cobas® HCV accurately detects and quantifies all HCV genotypes 1 through 6
Two non-overlapping detection probes, when combined with two staggered primers, ensure assay performance with HCV isolates containing sequence heterogeneity.
Mismatch tolerance that enables the test to accurately quantify the target despite nucleotide changes in the viral genome while maintaining high specificity for HCV RNA.
Clinical Relevance
Clinicians rely on regular HCV viral load assessment to achieve an optimal treatment outcome. Depending on the treatment regimen, HCV RNA measurements are made at baseline to identify likely treatment responders, to assess patient adherence during therapy, to determine if the treatment should be abbreviated or abandoned (futility rules) or that treatment has been successful and sustained virological response (SVR) has been achieved.
cobas® HCV delivers:
Tight precision at medically-relevant decision points
Accurate detection and quantification of HCV genotypes 1 through 6
High sensitivity suitable for use with new HCV therapies
Excellent correlation with the cobas® AmpliPrep/cobas® TaqMan® HCV Quantitative Test, v2.
Furthermore, cobas® HCV is approved as an aid in the diagnosis of HCV to confirm active infection in individuals with HCV antibody evidence.
Intended Use
cobas® HCV is an in vitro nucleic acid amplification test for both the detection and quantitation of hepatitis C virus (HCV) RNA, in human EDTA plasma or serum, of HCV-infected individuals. Specimens containing HCV genotype 1 to 6 are validated for detection and quantitation in the assay.
The test is intended for use as an aid in the diagnosis of HCV infection in the following populations: individuals with antibody evidence of HCV with evidence of liver disease, individuals suspected to be actively infected with HCV antibody evidence, and individuals at risk for HCV infection with antibodies to HCV. Detection of HCV RNA indicates that the virus is replicating and therefore is evidence of active infection.
The test is intended for use as an aid in the management of HCV-infected patients undergoing anti-viral therapy. The assay measures HCV RNA levels at baseline and during treatment and can be utilized to predict sustained and non-sustained virological response to HCV therapy. The results must be interpreted within the context of all relevant clinical and laboratory findings.

Features and Benefits
Broad coverage of all known HBV genotypes (A-H) including pre-core mutations
Tight precision at medically relevant decision points
Excellent performance with serum and plasma specimens
Built-in contamination control with AmpErase enzyme to prevent carryover contamination
Excellent correlation to Roche COBAS® AmpliPrep/COBAS® TaqMan® HBV Test, v2.0
Intended Use
cobas® HBV is an in vitro nucleic acid amplification test for the quantitation of hepatitis B virus (HBV) DNA in human EDTA plasma or serum of HBV-infected individuals. This test is intended for use as an aid in the management of patients with chronic HBV infection undergoing anti-viral therapy. The test can be used to measure HBV DNA levels at baseline and during treatment to aid in assessing response to treatment. The results from cobas® HBV must be interpreted within the context of all relevant clinical and laboratory findings.
