Intensificar o reforço das abordagens de monitorização do tratamento através dos testes da carga viral, assim como o diagnóstico pediátrico precoce, será fundamental para garantir cuidados e tratamentos de boa qualidade e o êxito dos programas. Considerar uma boa rede de diagnósticos, tipos... de amostras, intervenções e estratégias em cada um dos países e em todas as partes interessadas nacionais, regionais e parceiros contribuirá para apoiar este esforço, melhorar a colaboração e maximizar o investimento nos diagnósticos para um impacto clínico visível.

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.

A GTFCC course on sample collection and testing with rapid diagnostic tests (or RDTs) for cholera, for healthcare workers.
SARS-COV-2 antigen rapid diagnostic tests are an alternative option for diagnosing active SARS-CoV-2 infection through detection of viral proteins. Rapid antigen tests revolutionize the response to COVID-19 by providing accurate test results in 10 to 20 minutes instead of days, allowing tests to be ...done at point of care, and dramatically lowering the price of the tests.
Proper training on the safe use and implementation of antigen tests is vital to ensuring quality testing. A comprehensive training package around safety, sample collection, testing, reporting and management of antigen tests can be found below.
The training package includes facilitators’ guides for master trainers and trainers, training presentations, and supplementary materials to aid in the delivery of this training.

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.

All personnel performing SARS-CoV-2 antigen rapid diagnostic tests (Ag-RDT) need to understand how to safely perform testing, ensure quality testing and interpret results. This course is developed to provide theoretical knowledge on SARS-CoV-2 Ag-RDT testing. The learning package consists of 10 modu...les, which include recorded presentations and videos.

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

This document provides brief information answering common questions regarding COVID-19 diagnostic tests and how to prioritize them to the patients most in need.
The Interim Guidance on Cholera Rapid Diagnostic Tests (RDTs) by the Global Task Force on Cholera Control (GTFCC) provides recommendations for using RDTs to detect cholera in areas with limited laboratory capacity. It highlights the advantages of RDTs, such as rapid detection (within 30 minutes), ea...se of use by non-laboratory personnel, and their role in early outbreak identification and surveillance. However, it emphasizes that RDTs should not replace culture or PCR testing, as they vary in sensitivity (58-100%) and specificity (60-100%). The document advises on proper test selection, storage, training, and integration into national surveillance systems to enhance cholera response efforts.

This Rapid Communication aims to inform national TB programmes and other stakeholders about the key implications of the latest evidence on the use of specific molecular assays as initial diagnostic tests of pulmonary and extrapulmonary TB and RR-TB, in adults and children.
In 2007, the Sixtieth World Health Assembly adopted resolution WHA60.13 on control of leishmaniasis, urging Member States, among other actions: to strengthen prevention, active detection and treatment of cases of both cutaneous and visceral leishmaniasis in order to decrease the disease burden; and ...to strengthen the capacity of peripheral health centres to deliver primary and secondary care, so that they provide appropriate affordable diagnosis and treatment and act as sentinel surveillance sites.

This updated manual provides a basic understanding of the principles of laboratory and point-of-care (POC) testing in the context of screening and diagnostic approaches, as well as antimicrobial susceptibility testing, as components of sexually transmitted infections (STIs) control. As with previous... editions, this manual covers each disease in a separate chapter which provides detailed information on specimen collection, transport and laboratory testing. Two useful annexes covering media, reagents, diagnostic tests and stains (recipes) and laboratory supplies are included at the end of the manual.
