The first version of the National laboratory testing indication guidance for COVID-19 document was developed at the beginning of the COVID-19 outbreak. It was based on the scientific knowledge and testing resources available at that time, and reflects that testing was limited to molecular polymerase chain reaction (PCR). The original guidance document was finalized and approved by the Special Advisory Committee on April 16, 2020.
Since then, significant developments in four areas have prompted the need to review and update the guidance. Specific developments include:
- Expanded laboratory resources;
- Viral transmission from asymptomatic individuals or individuals in the pre-symptomatic phase;
- Outbreaks in congregate living and work settings; and
- New testing modalities (molecular Point of Care and serological tests).
This document was updated in May 2020 to reflect these developments. It will be updated continuously as new testing technologies become available, epidemiology changes and more is learned.
