It is actually now clear from a number of studies that getting treatment as quickly as possible after aids thai surpasses waiting. HIV-infected patients who happen to be treated early have fewer complications from HIV infection and so are less likely to infect others as opposed to those who wait to be treated. Studies also show individuals who know they may be HIV-positive may change their behavior to lower the risk of infecting others.
Globally, approximately 45% of men and women coping with HIV know about their HIV status, far below the 90% target lay out recently by WHO and UNAIDS. The very best numbers of people experiencing undiagnosed HIV are in sub-Saharan Africa, where fragile health and laboratory systems have hindered efforts to scale up HIV testing coverage. In low-income, high HIV burden countries with limited technological infrastructure, rapid diagnostic tests (RDTs) are widely used in diagnostic algorithms.
RDT accuracy might be undermined by poor operator practice , and by storage at ambient temperatures above manufacturer guidelines . Poor accuracy of RDTs and subsequent misclassification may result in a) if falsely diagnosed HIV-positive, unnecessary worry and initiation on antiretroviral therapy; or b) if falsely diagnosed HIV-negative, missed opportunities for linkage to HIV care and prevention services
The scale-up of HIV self-testing (HIVST) using oral fluid testing will pose additional challenges to maintaining accuracy in HIV testing programmes. Self-testing is based on somebody performing and interpreting their own personal HIV test result. Oral fluid RDTs meant for self-testing could be saved in uncontrolled settings (e.g. people’s houses) 57dexlpky prolonged periods before use and they are less amenable to formal quality assurance (QA) programmes . We therefore set out to judge two areas of RDT kit stability: the outcome of prolonged field being exposed to high temperature on the accuracy of whole blood and oral fluid RDTs; as well as the stability of oral RDT results with delayed visual re-reading.
In October 2004, conventional HIV testing was changed when OraSure Technologies, Inc., announced that this had Usa FDA approval for the rapid HIV test that will detect antibodies to both HIV-1 and HIV type 2 (HIV-2). This is called the OraQuick Advance Rapid HIV-1/2 Antibody Test. It was the 1st available test that could provide leads to 20 mins using oral fluid, a finger-stick sample of blood, or plasma. Rapid HIV testing is now strongly recommended and is among the most mainstay of many HIV screening programs.
