It really is now clear from several studies that getting treatment without delay after aids thai surpasses waiting. HIV-infected patients who happen to be treated early have fewer complications from HIV infection and therefore are not as likely to infect other people than those who wait to be treated. Studies also show that people who know they can be HIV-positive may change their behavior to diminish the chance of infecting others.
Globally, an estimated 45% of people coping with HIV understand their HIV status, far beneath the 90% target set out recently by WHO and UNAIDS. The best numbers of people coping with undiagnosed HIV will be 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 popular in diagnostic algorithms.
RDT accuracy can be undermined by poor operator practice , and also 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 defined by an individual performing and interpreting their own personal HIV test result. Oral fluid RDTs intended for self-testing can be kept 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 effect of prolonged field contact with high temperature in 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 U.S. FDA approval for a rapid HIV test that could detect antibodies to both HIV-1 and HIV type 2 (HIV-2). This is known as the OraQuick Advance Rapid HIV-1/2 Antibody Test. It absolutely was the 1st available test that can provide brings about twenty or so minutes using oral fluid, a finger-stick sample of blood, or plasma. Rapid HIV testing is now strongly suggested and has become the mainstay of many HIV screening programs.
