Scientists develop HIV monitoring devices

Release date: 2009-06-12

Australian scientists have developed a new test system that allows patients to find out if they need antiretroviral therapy within 30 minutes without any laboratory equipment being required. The Burnet Institute of Melbourne, Australia, was rewarded for this invention, and the system is low-cost, point-of-care, especially suitable for telemedicine. The study was completed by Professor Susan Crow, Associate Professor David Anderson, and senior scientist Mary Garcia.

The CD4 rapid test system is similar to the home pregnancy test, using finger pricking blood to obtain the number of CD4 + T cells measured by the standard. CD4 + T cells are vital to the healthy functioning of the immune system and are slowly destroyed after infection with AIDS. When CD4 + T cells are reduced to critical levels in human blood, they are increasingly susceptible to disease. Healthcare workers rely on CD4 cell counts to determine when HIV-positive patients begin antiretroviral therapy.

In the first phase of the trial, scientists will conduct further validation and clinical studies to ensure that the test provides reliable and reproducible results.
