This report, published in conjunction with a summary overview of results of rounds 1–8, is the eighth and final report in a series of laboratory-based evaluations of rapid diagnostic tests (RDTs) for malaria. It provides a comparative measure of their performance in a standardized way to distingu...ish between well and poorly performing tests.
These results constitute the laboratory evaluation component of the WHO prequalification process for malaria RDTs and inform the current WHO procurement recommendations. In round 8, 35 RDTs from 17 manufacturers were assessed. For the first time the evaluation included an assessment of product performance against a panel of P. falciparum parasites with pfhrp2/3 gene deletions and therefore not expressing HRP2.

The Alere Filariaisis Test Strip (FTS) is a diagnostic test used to detect filarial antigens for lymphatic filariasis. This training video was developed by ENVISION in collaboration with the US Centers for Disease Control and Prevention, with funding provided by the US Agency for International Deve...lopment.

L’OMS recommande aux femmes enceintes de faire un test de dépistage du VIH, de la syphilis et de l’hépatite B (HBsAg) au moins une fois pendant la grossesse, de préférence au cours du premier trimestre. Le double test de diagnostic rapide (TDR) VIH/syphilis peut être utilisé comme premier ...test pour les femmes enceintes dans le cadre des soins prénataux. Ces tests simples peuvent être utilisés sur le lieu de soins et sont économiques par rapport aux tests standards de soins prénataux.

The development of this target product profile (TPP) was led by the WHO Department of Control of Ne-
glected Tropical Diseases (NTD) following standard WHO guidance for TPP development. In order to
identify and prioritize diagnostic needs, a WHO NTD Diagnostics Technical Advisory Group (DTAG)
was... formed, and different subgroups were created to advise on specific NTDs, including a subgroup
working on the human African trypanosomiasis (HAT) diagnostic innovation needs. This group of in-
dependent experts included leading scientists, public health officials and endemic-country end-user rep-
resentatives. Standard WHO Declaration of Interest procedures were followed. A landscape analysis of
the available products and of the development pipeline was conducted, and the salient areas with unmet
needs were identified

In 2013, WHO and the Foundation for Innovative New Diagnostics convened a meeting of Buruli ulcer experts in Geneva, Switzerland (9) at which two priority unmet needs in diagnosis were identified:
a diagnostic test for early detection of Buruli ulcer in symptomatic patients with sufficient positive... predictive value to put patients on appropriate treatment; and
a screening test at the primary health care or community level for symptomatic patients with ulcer
In March 2018, they convened a global meeting with the aim of establishing an action plan to develop new diagnostic solutions for Buruli ulcer and to create a framework of collaboration to address unmet needs in diagnostics for the disease. The participants agreed to develop a target product profile (TPP) to address the need for a rapid diagnostic test for use at the primary health-care level.

Limited coverage of laboratory services and long turnaround times from real-time reverse transcription-polymerase chain reaction (rRT-PCR) for the detection of Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) has been insufficient to meet the demands in many African countries in response... to the COVID-19 pandemic. Rapid antigen diagnostic tests (AgRDTs) are potentially useful as they can inform healthcare workers and individuals of their infection status at point-of-care testing

Policy Brief.
WHO recommends that pregnant women receive testing for HIV, syphilis and hepatitis B (HBSAg) at least once during pregnancy, preferably in the first trimester.
Dual HIV/syphilis rapid diagnostic tests (RDTs) can be used as the first test for pregnant women as part of antenatal care (...ANC).
These simple tests can be used at the point-of-care and are cost-saving compared to standard testing in ANC. They enable more women to be diagnosed with HIV and syphilis so that they can access treatment and prevent transmission to their children.

Lymphatic filariasis (LF) is a parasitic disease that is a major cause of chronic disability in the developing world. According to the 2021–2030 road map for neglected tropical diseases (NTDs) published by the World Health Organization (WHO), the global goal for LF is elimination as a public healt...h problem by 2030 through repeated rounds of mass drug administration (MDA). Critical components of any elimination program are monitoring and surveillance. Appropriate assessment tools and methods are needed for each stage of an elimination program; mapping to identify which areas require intervention, monitoring to assess the impact of interventions, and post-intervention surveillance to validate elimination or detect recrudescence.
