cobas® HIV-1/HIV-2 Qualitative Test

Stay one step ahead, enable diagnosis as early as possible

Drive better decisions for a positive impact on patients’ lives

cobas® HIV-1/HIV-2 Qualitative Test for use on the cobas® 6800/8800 Systems is the first automated nucleic acid test to enable differentiation between HIV-1 and HIV-2 infections, applying the clinically proven dual target design (gag and LTR) for HIV-1. During seroconversion studies in 25 commercially available panels, cobas® HIV-1/HIV-2 detects HIV on average one week earlier than serology. cobas® HIV-1/HIV-2 offers flexible testing features (plasma, serum, dried blood spots for early infant diagnosis), highest throughput and absolute automation with ready-to-use reagents.

  • Diagnose HIV positive patients as early as possible
  • Confidently treat patients based on HIV subtype infection
  • Reliably inform mothers that their child is not infected and eliminate concerns about HIV status

cobas® HIV-1/HIV-2 Qualitative ordering Information

Intended use

cobas® HIV-1/HIV-2 Qualitative nucleic acid test for use on the cobas® 6800/8800 Systems is an in vitro nucleic acid amplification test for the qualitative detection and differentiation of human immunodeficiency virus (HIV) type 1 (HIV-1) and type 2 (HIV-2) in human serum, plasma, and dried blood spots (DBS).

The test is intended to be used as an aid in diagnosis of HIV-1/HIV-2. Detection of HIV-1 or HIV-2 nucleic acid is indicative of HIV-1 or HIV-2 infection, respectively. The presence of HIV-1 or HIV-2 nucleic acid in the plasma or serum of individuals without antibodies to HIV-1 or HIV-2 is indicative of acute or primary infection. In infants born to HIV-infected mothers and who have maternal antibodies to HIV-1 or HIV-2, the presence of HIV nucleic acid is indicative of active infection. cobas® HIV-1/HIV-2 Qualitative may also be used to confirm HIV-1 or HIV-2 infection in an individual with specimens reactive for HIV-1 or HIV-2 antibodies or antigens.
