Detection and quantitation of Hepatitis B virus (HBV) in less than one hour
Xpert® HIV-1 Qual XC
A molecular point-of-care test that delivers actionable results in around 90 minutes
The World Health Organization estimated that 38 million people worldwide were living with HIV at the end of 2019.1
Infected individuals generally develop an acute infection characterized by flu-like symptoms in a period of days to weeks after initial exposure.2 Acute HIV infections typically last less than 14 days3 and are associated with high levels of viremia prior to a detectable immune response.4-6Therefore, HIV-1 nucleic acid testing is more sensitive than standard serologic testing in detection of acute infection.
The need for a highly sensitive HIV qualitative test to detect HIV infection early in high risk and vulnerable populations is greater than ever. To improve patient care for all patients and reduce viral transmission in communities, a rapid answer on a whole blood (WB) or dried blood spot (DBS) sample is necessary.
Xpert HIV-1 Qual XC (extended coverage) is an in vitro nucleic acid amplification test for the qualitative detection of HIV-1 total nucleic acids, on the automated GeneXpert® System.
Xpert HIV-1 Qual XC is intended to aid in the diagnosis of HIV-1 infection in conjunction with clinical presentation and other laboratory markers in infant, adolescent, and adult populations..
- Extended coverage for HIV-1 strains with dual target detection
- 2 protocols; Only 100ul capillary/EDTA venous WB or a single DBS
- Simply load the sample and run the test. No additional preparation required for WB or DBS
- Includes point-of-care testing
- Improved cartridge chemistry with addition of sample adequacy control (SAC) to verify human specimen and removal of guanidinium thiocyanate (GTC) for safer cartridge disposal
- Improve access for HIV testing: Designed for near patient testing in any setting allowing faster delivery of results and medical follow up. Simple sample collection and testing with results in ~90 minutes
- Detect acute Infections: Earlier detection than serology based methods provides an important opportunity to improve management of those at risk of recent infections and prior to initiating PrEP
- Reduce time from testing to treat: Fast track initiation of treatment with point-of-care HIV-1 nucleic acid test confirmation

Early diagnosis of HIV and use of molecular Point-of-Care HIV testing as part of a comprehensive strategy to end HIV transmission
According to UNAIDS1 the world is embarking on a Fast-Track strategy to end the AIDS epidemic by 2030. There is a strong global consensus that powerful tools now exist to end the AIDS epidemic. HIV treatment can dramatically extend the lifespan of people living with HIV and effectively prevent HIV transmission. HIV testing is a crucial element, where a positive result offers the opportunity to start treatment as soon as possible and a confirmed negative result opens the possibility to start quickly with Pre-Exposure Prophylaxis (PrEP). On the other side, HIV programs will only be effective if community groups and organisations are part of the implementation. This webinar will explore the benefits of molecular Point-Of-Care HIV testing, within the context of a community centre for men who have sex with men (MSM) and Transgender Women (TW), for three different applications: confirmation of a positive HIV rapid test, detection of an acute HIV infection, and screening of acute infections at the start of PrEP. 1 http://www.unaids.org/sites/default/files/media_asset/JC2686_WAD2014report_en.pdf CE-IVD.
