Se estima que unos 10 millones de personas contrajeron tuberculosis (TB) en el 2019 y que a unos 3 millones de ellas no se les diagnosticó ni se les notificó la enfermedad. Con el propósito de poner fin a la epidemia mundial de la tuberculosis para el 2030, sigue siendo necesario ampliar la capac...idad para analizar un gran número de muestras.

The purpose of this document is to provide guidance on the use of pooled sample testing strategy in coronavirus disease (COVID-19)
testing laboratories of the African Union Member States for scaling up SARS-CoV-2 nucleic acid testing capacity with the available resources. The current document descr...ibes the effect of factors such as the prevalence of COVID-19 in the population to be tested, the homogeneity of pools, and the sensitivity of the molecular test in optimal pool size determination. It also highlights the importance of monitoring the prevalence of COVID-19 in a population to be tested and proper validation of the test, to limit the potential for false-negative results. Validation studies to determine the optimal pool size by testing laboratories are recommended as the optimum approach. A safe, simple ‘two-stage pooling’ option has been indicated in this guidance to be used by laboratories until such validation can be achieved.

This Laboratory Assessment Tool (LAT) is specifically designed to assess capacities of existing laboratories which have implemented or aim to implement SARS-CoV-2 testing. It addresses both core capacities of a laboratory and specificities related to SARS-CoV-2 testing. It is a focused... and shorter version from the existing complete laboratory assessment tool that can be found at https://www.who.int/ihr/publications/laboratory_tool/en/
The target audience is any stakeholder performing laboratory assessments such as national health authorities, multilateral agencies, Non-Governmental Organizations (NGOs) and laboratory managers. Assessors can use the tool, and customized if needed, to meet local requirements or assessment context. This tool is an Excel file, which enables automatic calculations of module indicators.
