As of April 8, 2020, the global health threat now known as coronavirus disease-2019 (COVID-19) had infected more than 1.3 million people in over 200 countries and caused more than 79,000 deaths1. According to the “Operational Planning Guidelines to Support Country Preparedness and Response” developed by the World Health Organization (WHO), a coordinated global response plan that primarily involves prevention of human-to-human transmission of the virus, caring and monitoring of infected patients, and rapid diagnosis of the disease followed by effective infection control measures is required to control the COVID-19 pandemic2.

Within weeks of the first identified cases of the SARS-CoV-2, the viral genome was sequenced and released publicly for immediate public health support3-7. Since then, several diagnostic assays have been developed, both in-house and commercial, for the rapid detection and identification of this novel coronavirus pathogen. However, as the number of confirmed infections continued to rise, global demand for testing expanded well beyond existing reagent production capacity. Medical and laboratory professionals and manufacturers around the world voiced concerns about the impact of existing regulations on the use of diagnostic tests by medical laboratories during the COVID-19 outbreak8. Regulatory agencies, such as the FDA in the United States, responded quickly with revised Emergency Use Authorization (EUA) regulations and requirements to expand testing for SARS-CoV-2, allow medical laboratories to use their local laboratory developed tests (LDTs) before FDA clearance, and allow companies to rapidly receive regulatory approval upon appropriate clinical validation and submission of data9,10.

As of April 7, 2020, 30 molecular assays for SARS-CoV-2 testing have received FDA EUA in the United States and are commercially available for diagnostic testing (In vitro Diagnostics EUAs). Similarly, several in-house and commercial molecular tests and immunoassays have been developed globally and have been approved by other regulatory agencies. They are currently being validated by several laboratories (SARS-CoV-2 Diagnostic assays).

As medical laboratories are working to bring testing for COVID-19 in-house, as well as organizing their respective laboratories to meet needs for additional safety measures, laboratory standards and guidelines can be critical resources for advice and guidance to help them navigate this global crisis. The Clinical and Laboratory Standards Institute (CLSI) has compiled a list of relevant guidelines and standards that can help our healthcare colleagues who are in the process of bringing on COVID-19 testing or modifying their laboratory processes to accommodate the high demand for testing. Additionally, guidance documents and assessment tools released by the World Health Organization (WHO) can be particularly useful to laboratories that are currently involved in COVID-19 testing11-13.
