It is actually now clear from a variety of studies that getting treatment as quickly as possible after hiv test kits is preferable to waiting. HIV-infected patients who definitely are treated early have fewer complications from HIV infection and so are unlikely to infect other folks than others who wait to be treated. Studies also show individuals who know they are HIV-positive may change their behavior to reduce the chance of infecting others.
Globally, an estimated 45% of men and women coping with HIV are aware of their HIV status, far below the 90% target lay out recently by WHO and UNAIDS. The very best numbers of people coping with undiagnosed HIV are in sub-Saharan Africa, where fragile health insurance 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 can be undermined by poor operator practice , and through storage at ambient temperatures above manufacturer guidelines . Poor accuracy of RDTs and subsequent misclassification could lead to 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 defined by someone performing and interpreting their particular HIV test result. Oral fluid RDTs designed for self-testing may be saved in uncontrolled settings (e.g. people’s houses) 57dexlpky prolonged periods before use and therefore are less amenable to formal quality assurance (QA) programmes . We therefore set out to judge two elements of RDT kit stability: the effect of prolonged field being exposed to high temperature in the accuracy of whole blood and oral fluid RDTs; and also the stability of oral RDT results with delayed visual re-reading.
In October 2004, conventional HIV testing was changed when OraSure Technologies, Inc., announced it had Usa FDA approval for a rapid HIV test that could 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 had been the 1st available test that could provide leads to twenty minutes using oral fluid, a finger-stick sample of blood, or plasma. Rapid HIV testing is now strongly recommended and is one of the mainstay on most HIV screening programs.
