The Need
- Measurement of blood plasma HIV-1 RNA using PCR is established as the standard of care in assessing HIV-positive patient prognosis and response to antiretroviral therapy
- It is estimated that only 75% of people living with HIV worldwide have access to viral load testing. In Low and Middle-Income Countries (LMICs), this figure is below 50%1
- HIV viral load tests that can be deployed beyond centralized laboratories are needed to expand access to the standard of care.1

The Solution
- The Xpert HIV-1 Viral Load XC test is an on-demand quantitative PCR test incorporating dual target detection for extended strain coverage
- Using GeneXpert® technology, the Xpert HIV-1 Viral Load XC test automates the test process in one fully integrated cartridge and enables testing in laboratory or near‑patient testing environments
- Provides users with advantages of simple workflow, fast results, and flexibility for low-to-high volume testing
Xpert® HIV‑1 Viral Load XC is intended to be performed by trained professional users or trained healthcare workers in laboratory or near-patient testing environments.
The Impact
- Improve Patient Care: Enable better treatment options by reduced loss to follow-up and shorter turn-around times between sample collection and reporting results to patients2
- Increase Efficiency: Fast results enable earlier interventions with counseling and therapy2,3
- Increase access to viral load testing: Deliver lab-quality results in multiple settings3,4
