Previous studies have highlighted a range of individual determinants associated with HIV testing but few have assessed the role of contextual factors. The objective of this paper is to examine the influence of both individual and community-level determinants of HIV testing uptake in Burkina Faso.

In a prospective cohort study in Bangwe primary care clinic, Blantyre, Malawi, all adults (18 years or older) presenting with an acute illness were screened for TB symptoms (cough, fever, night sweats, weight loss). Demographic characteristics were linked to exit interview by fingerprint bioidentifi...cation. Multivariable logistic regression models were constructed to estimate the proportion completing same-visit HIV testing, comparing between those with and without TB symptoms.

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 Reports suggest that misdiagnosis of HIV status may occur when suboptimal testing algorithms and out-of-date testing strategies are used.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.
