Because the signs and symptoms of coronavirus disease 2019 (COVID-19) may overlap with those of other respiratory pathogens, it is important to perform laboratory testing to specifically identify symptomatic individuals infected with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). Moreover, it is estimated that up to 40% of people with SARS-CoV-2 infection may be asymptomatic (subclinical infection) or presymptomatic, and still potentially capable of transmitting the virus to others. [1, 2]  Therefore, in certain cases, individuals without obvious signs or symptoms of SARS-CoV-2 infection also require testing.
