The speed of developing diagnostics for SARS-CoV-2, the causative agent of coronavirus disease 2019 (COVID-19), has been quite remarkable. Diagnostics have focused on nucleic acid amplification testing (NAAT) to identify infected individuals in acute-phase disease for timely implementation of mitiga...tion strategies and case management. More and more immunodiagnostics, mostly rapid diagnostic tests, are being made available as an alternative to NAATs. This type of test can be used out-of-laboratory conditions at large scale.

orientations provisoires, 25 juin 2021. Des tests de diagnostic rapides et précis sont un outil essentiel pour prévenir et contrôler la propagation du COVID-19. Ce document décrit les recommandations relatives aux stratégies nationales de dépistage et à l'utilisation de la PCR et des tests an...tigéniques rapides dans différents scénarios de transmission de l'épidémie de COVID-19, y compris la manière dont les tests pourraient être rationalisés dans les milieux à faibles ressources. Tous les tests doivent être suivis d'une réponse de santé publique forte, comprenant l'isolement des personnes dont le test est positif et la fourniture de soins, la recherche des contacts et la mise en quarantaine des contacts.

FIND and Standard Diagnostics (SD) have developed a lateral flow rapid diagnostic test (RDT) to screen for
T.b. gambiense HAT that is cheap and easy to use. The tests are packed individually and are stable at 40°C for
up to 25 months; they are performed on fresh blood obtained from a finger prick..., and no instrument or electricity is required. The RDT detects host antibodies to infection in populations that are at risk, or in suspect individuals. Positive cases are subjected to further confirmatory methods to identify HAT patients.

Three classess of tests are now recommended in the latest consolidated guideles on tests for tuberculosis infection. It includes for the first-time a new class of Mycobacterium tuberculosis antigen-based skin tests (TBSTs), and the two existing classes of tests: the tuberculin skin test (TST) and t...he interferon-gamma release assays (IGRAs).
IGRAs and TBSTs use Mycobacterium tuberculosis complex specific antigens and represent a significant advancement to TST which has been used for over half a century.

This document updates recommendations for HIV testing by laboratories in the United States and offers approaches for reporting test results to persons ordering HIV tests and to public health authorities. The recommended algorithm is a sequence of tests used in combination to improve the accuracy of ...the laboratory diagnosis of HIV based on testing of serum or plasma specimens. The updated recommendations also include tests for HIV antigens and HIV nucleic acid because studies from populations at high risk for HIV demonstrate that antibody testing alone might miss a considerable percentage of HIV infections detectable by virologic tests

6 July 2021. Three new nucleic acid amplification test (NAAT) classes are endorsed by WHO and included.
The latest operational handbook includes the new classes recommended by WHO. It aims at facilitating the implementation of the WHO recommendations by the Member States, technical partners, and ot...hers involved in managing patients with TB and DR-TB. The operational handbook provides practical information on existing and new tests recommended by WHO, step-by-step advice on implementing and scale-up testing to achieve local and national impact and lastly, model diagnostic algorithms, which are updated to incorporate the latest recommendations. An overview of budgetary considerations and information sheets on each of the newly recommended tests is provided.

These consolidated guidelines on HIV testing services (HTS) bring together existing and new guidance on HTS across different settings and populations.
The World Health Organization (WHO) first released consolidated guidelines on HTS in 2015, in response to requests from Member States, national pr...ogramme managers and health workers for support to achieve the United Nations (UN) 90–90–90 global HIV targets – and specifically the first target of diagnosing 90% of all people with HIV. In 2016, based on new evidence, WHO released a supplement to address important new HIV testing approaches – HIV self-testing (HIVST) and provider-assisted referral.
Since the release of 2015 and 2016 HTS guidelines, new issues and more evidence have emerged. To address this, WHO has updated guidance on HIV testing services. In this guideline, WHO updates recommendation on HIVST and provides new recommendations on social network-based HIV testing approaches and western blotting (see box, next page). This guideline seeks to provide support to Member States, programme managers, health workers and other stakeholders seeking to achieve national and international goals to end the HIV epidemic as a public health threat by 2030.
These guidelines also provide operational guidance on HTS demand creation and messaging; implementation considerations for priority populations; HIV testing strategies for diagnosis HIV; optimizing the use of dual HIV/syphilis rapid diagnostic tests; and considerations for strategic planning and rationalizing resources such as optimal time points for maternal retesting

This was a school-based cross-sectional study conducted in 2015 among 305 school children aged 7–16 years from two primary schools located in Ilemela and Magu Districts, north-western Tanzania. Single stool and urine samples w...ere collected from each participant and examined for the presence of Schistosoma mansoni eggs, parasite antigen, and parasite DNA using KK thick smears, POC-CCA tests, and real-time PCR, respectively.
