Global guidelines continue to be updated as evidence on best practice in caring for and treating people living with HIV is gathered. CD4 testing is one of the steps taken to initiate people living with HIV/AIDS onto ART and is an effective tool in determining the immunological status of patients, in prioritising patients at risk of Opportunistic Infections and in prioritising patients for initiating ART where Treat All is still not a realistic option.
Current laboratory-based methods for CD4 testing often require venous blood draw and involve a lengthy waiting time that may result in the patient being lost to follow up. There are also considerable costs in maintaining CD4 testing instruments and it is commonly the case that health worker staff turnover is high which means that competencies are diluted.
VISITECT® CD4 is an instrument-free, disposable, point-of-care (POC) test for determining CD4 baseline in people living with HIV.
POC tests improve the management of HIV/AIDS, especially in resource-limited settings. The benefit of rapid results during a single visit to the healthcare facility is timely initiation of appropriate therapy, and facilitation of linkage to care and referral.
VISITECT® CD4 is an innovative diagnostic solution offering immediate patient results that support the continuum of care in resource-limited settings.
VISITECT® CD4 is a ground-breaking, disposable, POC test for determining CD4 baseline in people living with HIV. Developed by the Burnet Institute in Melbourne, Australia, it is based on proven lateral flow technology and provides an affordable, convenient, instrument-free solution for use in laboratories and remote clinics worldwide, enabling ART therapy to become accessible to all people living with HIV.
With training, the test provides an easy-to-use, instrument-free option for a plethora of healthcare workers, including clinicians, laboratory technicians, nurses, community healthcare workers and counsellors.
Testing requires basic training, a drop of whole blood and a 40-minute waiting period. Results are semi-quantitative and can be read by eye.
The VISITECT® CD4 smartphone app allows for immediate reading, interpretation and transmission of results to a central database. FOR RESEARCH USE ONLY
The VISITECT® AX-2X instrument is a small, portable (600grams), battery-operated reader that is designed to facilitate a bench flow process. The VISITECT® AX-2X design promotes instant connectivity through a USB port and Ethernet connections, linking the device to a USB flash, a printer, internet, or cloud database. Results are exported as csv. files allowing for data to be configured, capturing valuable MIS and patient demographics for real time surveillance. FOR RESEARCH USE ONLY
