Reliable HIV genome detection
Targets two unique regions of the HIV-1 genome
It takes more than a single target
Trust in a reliable HIV-1 viral load monitoring test built upon the dual-target assay design, only from Roche.
The cobas® HIV-1 quantitative nucleic acid test for use on the cobas® 4800 Systems targets two unique regions of the HIV-1 genome to improve genotype inclusivity, detect HIV-1 variants and potentially avoid under quantification. The rapidly mutating HIV-1 virus can evade quantification with a single-target, viral-load assay.1,2
Get dual-target reliability for HIV-1 quantification
This dual-target approach improves test sensitivity, coverage and security in the event of mutation in one primer/probe region.
- Target two unique regions of the HIV-1 genome, gag and LTR, which are not subject to selective drug pressure
- Confidently detect HIV-1 variants and potentially avoid under quantification
Accurately quantify HIV-1 RNA with a dual-target assay and contribute to optimal treatment decisions for patient management
cobas® HIV-1 is an in vitro nucleic acid amplification test for the quantitation of human immunodeficiency virus type 1 (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 of disease progression 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.
