A New Standard in HIV-1 Confirmation and Viral Load Monitoring

FIRST and ONLY Dual Claim HIV-1 Assay

The Aptima HIV-1 Quant Dx Assay is intended for use:

  • To confirm HIV-1 infection in an individual whose plasma or serum specimen is reactive with an approved assay with an indication as an aid in the diagnosis of HIV-1 infection.

  • In conjunction with clinical presentation and other laboratory markers for disease prognosis and for use as an aid in monitoring the effects of antiretroviral treatment

A highly sensitive assay for reliable quantitation of HIV-1 RNA.

Limit of Detection (LoD): The Aptima HIV-1 Quant Dx assay can detect HIV-1 RNA as low as 12 copies/mL using a 0.5-mL sample.1

Repeatable, reliable results.

The Aptima HIV-1 Quant Dx assay delivers high precision in quantitation, with a narrow coefficient of variation across the linear range—including in low-viremia samples—for results you can trust.1

Ensures HIV-1 can be accurately quantified across major groups and subtypes.

The LoD has been thoroughly verified across HIV-1 groups M, N, and O with multiple replicates and multiple reagent lots.1

Thoughtful assay design to guard against mutations.

The Aptima HIV-1 Quant Dx assay provides 3 levels of protection for confidence in assay performance despite drug selection pressures and growing genetic diversity3:

  • Dual-target approach for built-in redundancy, with both targets chosen within highly conserved genomic regions of HIV-1 (LTR and pol) to ensure accurate quantitation.

  • Sophisticated primer design—including length—to tolerate mutations.

  • Redundant oligonucleotides for additional protection.
