Xpert® HIV-1 Viral Load
Detection and quantification of Human Immunodeficiency Virus type 1 (HIV-1) in around 90 minutes
The Need
The World Health Organization estimated that 38 million people worldwide were living with HIV at the end of 2019.1
Today, measurement of blood plasma HIV-1 RNA concentration (known as HIV viral load) using nucleic
acid- based molecular diagnostic assays has been established as the standard of care in assessing
HIV-positive patient prognosis and response to antiretroviral therapy. Assessment of viral load levels
is a strong predictor of the rate of disease progression and, by itself or in combination with CD4 T-cell counts, has great prognostic value.2-7
The need for a rapid HIV viral load test with flexibility to adapt to any throughput requirements and random access for urgent samples is greater than ever because each individual patient deserves better care.
The Solution
Xpert HIV-1 Viral Load is a quantitative test that provides on-demand molecular testing.
Based on the GeneXpert® technology, Xpert HIV-1 Viral Load automates the test process including RNA extraction, purification, reverse transcription and cDNA real time quantitation in one fully integrated cartridge.
Redefining Simple:
Easy
- Run daily or on-demand
- No requirements for PCR room settings
- No daily maintenance or liquid waste management
Rapid
- 91 minutes run time with a viral load trend report*
- No batch, no delay
- Minimal hands-on time
Flexible
- Compatible with any lab volume
- Providing up to 403 viral load results per 8 hours^
- Random access 24/7 availability
- Run multiple different tests on the same platform at any time
- Quantification standards run in every test for fixed cost per reportable result independent of daily volume
* Trend report available for patients’ viral load measured multiple times on the same GeneXpert.
^ Operational throughput on Infinity-80; internal analysis.
The Impact
- Increase Efficiency: Simplified workflow and on demand testing reduces hands-on time
- Improve Patient Care: Rapid results enable earlier adjustments to appropriate therapy
- Better for patients: Same day results and treatment decisions reduces anxiety and time for clinical appointments
Move Your Lab Forward
- No Waiting: Run any test any time with 24/7 random access
- Simple & Organised: True 24/7 random access accommodates other urgent test requests
- Flexible: Adapt to any throughput requirement
- Improve Sample Processing: Speed up results turn around time to meet clinical need and deliver better service
