WHO regulations recognise accredited labs
The World Health Organisation’s International Health Regulations have been developed to prevent, protect against, control and provide a public health response to the international spread of disease in ways that are commensurate with and restricted to public health risks, and which avoid unnecessary interference with international traffic and trade. Economies are required to develop certain minimum core public health capacities. Access to accredited laboratories provides clear evidence of an economy’s sustainable ability to respond.
