Targets two unique regions of the HIV-1 genome on cobas® 6800/8800 Systems

It takes more than a single target

As the challenges you face evolve, stay one step ahead with cobas® HIV-1 for use on the cobas® 6800/8800 Systems, a next-generation, dual-target quantitative HIV-1 assay, only from Roche.

The cobas® HIV-1 quantitative nucleic acid test for use on the cobas® 6800/8800 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

Roche dual-target assays provide reliable results to confidently and effectively quantify HIV-1 with improved test sensitivity, coverage and security.

  • 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

Intended use

US-IVD

The 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 using the automated cobas® 6800/8800 Systems for specimen processing, amplification and detection. The test can quantitate HIV-1 RNA over the range of 20-10,000,000 copies/mL (33 to 1.67 x 107 International Units/mL).

This test is intended for use in conjunction with clinical presentation and other laboratory markers for the clinical management of HIV-1 infected patients. The test can be used 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.

The cobas® HIV-1 is not intended for use as a screening test for the presence of HIV-1 in donated blood or plasma or as a diagnostic test to confirm the presence of HIV-1 infection.

Accurately quantify and detect HIV-1

The innovative cobas® HIV-1 dual-target assay enables accurate detection and quantification even in the presence of drug-induced mutations, driving better decisions for a positive impact on patients’ lives.
