HIV testing programmes need to ensure that all clients who test for HIV are provided with correct diagnoses. The accuracy of HIV testing is critical to prevent misdiagnosis, as the consequences of giving an incorrect test result can be serious for clients, HIV testing services, HIV programmes and pu...blic health.
With the evolution of global HIV epidemiology, HIV testing approaches must also evolve to maintain accuracy and efficiency in population-level diagnosis. Reports suggest that misdiagnosis of HIV status may occur when suboptimal testing algorithms and out-of-date testing strategies are used. As a result of changing epidemiology and declining HIV positivity in testing, WHO recommends all countries use a standard three-test strategy to ensure a PPV of at least 99%, minimizing false-positive misdiagnosis. The WHO-recommended HIV testing strategy, along with quality assurance measures such as retesting to verify a positive diagnosis prior to initiation of HIV treatment, is cost-effective as it prevents misdiagnosis and unnecessary initiation of costly lifelong treatment.
This implementation guide provides practical advice on switching to a three-test strategy and instituting other measures that can help national HIV programmes deliver high-quality, accurate HIV testing services and ensure that misdiagnosis is minimized.

July 2021. This publication brings together important clinical and programmatic updates produced by WHO since 2016 and provides comprehensive, evidence-informed recommendations and good practice statements within a public health, rights-based and person-centred approach.
These guidelines bring in... the most recent guidance on HIV testing strategies - the entry point for HIV prevention and treatment - and include comprehensive guidance on infant diagnosis. Key recommendations are presented on rapid antiretroviral therapy (ART) initiation and the use of dolutegravir. Updated recommendations are included on the timing of ART for people with TB, and the use of point-of-care technologies for treatment monitoring.

What measures can we take to overcome the corona crisis, limit its consequences or use scarce resources efficiently? Every day we experience uncertainties and contradictions on these questions among scientists, health experts, politicians and in society. We must all strive for a broad consensus to o...vercome the global COVID-19 pandemic. With our publications IM FOKUS we want to stimulate discussion and promote opinion-forming: We write based on our experience of HIV work. We are not interested in COVID-19 to be equated with HIV, but to discuss which experiences from HIV work could be helpful in dealing with COVID-19. We do not intend to replace scientific papers, nor can we present the current state of knowledge comprehensively and conclusively.

Guidelines on lenacapavir for HIV prevention and testing strategies for long-acting injectable pre-exposure prophylaxis. Web Annex B
Men are underrepresented in HIV testing services throughout sub-Saharan Africa. HIV testing is critical to achieve the UNAIDS 95-95-95 goals, as it is the first entry point to HIV care. In Malawi, an estimated 14% of HIV positive men are undiagnosed, while only 6% of HIV positive women remain undiag...nosed. Improved HIV testing among men is key to reaching UNAIDS goals, and to curbing HIV epidemics in the region.

Due to the anticipated significant rise in VL testing occasioned by Ghana’s adaptation of 2016 ART guidelines, it has become necessary to develop this VL scale-up and operational plan to assure complete client access to laboratory monitoring towards the achievement of the third 90 of the HIV care ...cascade. The plan will enhance VL testing, monitoring whilst improving the clinical and laboratory interface for improved client care.

This policy brief describes key HIV viral load thresholds and the available viral load testing approaches for monitoring how well antiretroviral therapy is working for people living with HIV. It provides clarification for and elaborates upon the current treatment monitoring algorithm from the Consol...idated guidelines on HIV prevention, testing, treatment, service delivery and monitoring: recommendations for a public health approach.
This information can help people living with HIV to live healthy lives, ensure that HIV is not transmitted to other people and support policy-makers in determining the optimal allocation of resources for viral load testing and communicating the results.

People living with HIV who have a low CD4 count are at a much higher risk of falling ill from TB infection than HIV negative people.
It is important to offer both HIV testing to TB patients and TB diagnosis in HIV patients. Early detection and effective treatment are essential to preventing TB...-associated deaths.
WHO and UNAIDS have strongly advised countries to ensure that HIV programmes integrate regular TB screening, preventive therapy and early treatment.

This clinical job aid addresses the importance of maternal health and antiretroviral therapy adherence, as well as care and testing for the HIV-exposed infant until the infant’s final HIV diagnosis after the end of breastfeeding.
Since 2001, several Demographic and Health Surveys (DHS) include HIV
testing. For many countries, in particular in sub-Saharan Africa, DHS are
the only national source of data in general population. Several DHS collect
latitude and longitude of surveyed clusters but the sampling method is not
ap...propriate to derive local estimates: sample size is not large enough for a
direct spatial interpolation.
We developed a generic approach to map spatial regional trends of HIV
prevalence from DHS. We present how our results from Burkina Faso 2003
DHS shed new light on HIV epidemics.
