It can be now clear from a variety of studies that getting treatment without delay after hiv test is better than waiting. HIV-infected patients who happen to be treated early have fewer complications from HIV infection and they are less likely to infect others than those who wait to get treated. Studies also show people that know they can be HIV-positive may change their behavior to lower the danger of infecting others.
Globally, an estimated 45% of individuals managing HIV are aware of their HIV status, far below the 90% target set out recently by WHO and UNAIDS. The best numbers of people experiencing undiagnosed HIV happen to be 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 traditionally used in diagnostic algorithms.
RDT accuracy might be undermined by poor operator practice , and also by storage at ambient temperatures above manufacturer guidelines . Poor accuracy of RDTs and subsequent misclassification can 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-tests are defined by a person performing and interpreting their very own HIV test result. Oral fluid RDTs meant for self-testing might be stored 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 lay out to judge two aspects of RDT kit stability: the impact of prolonged field exposure to high temperature on the accuracy of whole blood and oral fluid RDTs; along with 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 it had United states FDA approval for any 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 absolutely was the 1st available test which could provide contributes to 20 mins using oral fluid, a finger-stick sample of blood, or plasma. Rapid HIV tests are now strongly recommended and is one of the mainstay of most HIV screening programs.
