HIV-1 drug resistance (HIVDR) genotyping is an essential component of the WHO global HIVDR surveillance strategy. Plasma “gold standard” specimen type for HIVDR genotyping, but its use may not be feasible in rural, remote areas in low- and middle-income countries, since preparing and storing it ...require personnel and laboratory infrastructure that are often lacking. An alternative specimen type is dried blood spots (DBS), which can be made without special laboratory processing. DBS are more easily transported than plasma because they can be shipped at ambient temperature as non-hazardous materials using regular mail or courier services.

Brief instructions for the diagnostic of specimens coming from suspected plague cases and exposed contacts, including recommendations for diagnostic confirmation
Aviation plays an important role in humanitarian operations around the world, especially in countries where overland transport is difficult or impossible due to insecurity, damaged or inadequate infrastructure, and challenging climatic conditions. Aviation allows the transport of humanitarian aid wo...rkers and humanitarian cargo to communities in some of the world’s most inaccessible places.

Antimicrobial Resistance Surveillance and Research Network | This document contains detail procedures on sample collection, transport, isolation, identification of fungi for the diagnosis of invasive fungal infections and antifungal susceptibility testing of yeast
This job aid provides information for laboratorians about how to receive, process, and store dried blood spot specimens collected for early infant diagnosis, viral load, or drug resistance testing.
Steps on how to safely collect oral swabs (saliva) from deceased patients suspected to be infected with Ebola: before entering patient’s room, how to put on and remove personal protective equipment (PPE), how to collect oral swab from deceased patient and how to prepare VTM collection tube for tra...nsport.

Any individual that meets the suspected case definition of monkeypox should be offered testing in appropriately equipped laboratories by staff trained in the relevant technical and safety procedures. Confirmation of monkeypox virus infection is based on nucleic acid amplification testing (NAAT), usi...ng real-time or conventional polymerase chain reaction (PCR), for detection of unique sequences of viral DNA. PCR can be used alone, or in combination with sequencing. The recommended specimen type for laboratory confirmation of monkeypox is skin lesion material, including swabs of lesion surface and/or exudate, roofs from more than one lesion, or lesion crusts.

The Practical manual on laboratory strengthening, 2022 update provides practical guidance on implementation of WHO recommendations and best practices for TB laboratory strengthening. It is an updated version of the GLI Practical Guide to Laboratory Strengthening published in 2017 and provides the la...test practical guidance on use of newly recommended diagnostics as well as guidance in key technical areas, including quality assurance and quality management systems, specimen collection and registration, procurement and supply-chain management, diagnostic connectivity, biosafety, data management, human resources, strategic planning, and model algorithms. The key changes are:
inclusion of recent or updated WHO recommendations for tests to diagnose TB and detect drug resistance;
alignment with the latest WHO critical concentrations for phenotypic drug-susceptibility testing (DST) and the new definitions of pre-XDR-TB and XDR-TB;
updated information on building quality-assured TB testing and management capacity using the Stepwise Laboratory Quality Improvement Process Towards Accreditation (SLIPTA) approach (Score-TB package1);
updated information on assessing, analysing and optimising TB diagnostic networks; and
updated information on the use of next-generation sequencing (NGS) to detect mutations associated with drug resistance for surveillance purposes.
The document also provides references to resources and tools relevant for work on laboratory strengthening.

This concept note describes the methods used to assess the prevalence of any HIVDR and HIVDR by PMTCT exposure among children less than 18 months of age using remnant dried blood spot specimens from early infant diagnosis over a 12-month period
The aim of the operational framework is to ensure 1) accurate collection, handling, shipment and storage of specimens collected in countries implementing HIV drug resistance surveillance; and 2) the availability of quality-assured HIV genotyping laboratory services producing comparable and reliable ...results at the national, regional and global levels.
This publication updates the WHO HIVResNet HIV drug resistance laboratory operational framework published in 2017 and reflects technical and strategic developments over the past three years.

Specific Objectives
• To increase the knowledge and awareness of personnel on chemical management.
• To educate the personnel on the potential adverse health effects of chemical exposure.
• To educate the personnel on the existing laws pertaining to handling of hazardous
chemicals.
• To... promote safe and healthy work practices among personnel during chemical handling.
• To guide the personnel on transportation, storage and disposal of hazardous chemicals.

Detonation of a nuclear weapon or activation of a radiological dispersal device could cause radioactively contaminated decedents. These guidelines are designed to address both of these scenarios. They could also be applicable in other instances where decedents’ bodies are contaminated with radioa...ctive material (e.g. reactor accidents, transportation accidents involving radioactive material, or
the discharge of a decedent from a hospital after injection or implantation of a radiopharmaceutical). These guidelines suggest ways for medical examiners, coroners, and morticians to deal with loose surface contamination, internal contamination, or shrapnel on or in decedents’ bodies.
