Saliva test could fill COVID-19 assessment gaps: Ottawa study

At the beginning of the pandemic, Ottawa surgeon Dr. Stephanie Johnson-Obaseki had a brainwave resulting in research that could lead to saliva testing becoming another tool in the toolbox of COVID-19 assessment. Saliva testing, while slightly less sensitive than nasal swabs, could play a role in rapidly expanding COVID-19 testing, especially in remote communities and in other challenging populations, such as long-term care residents and students.
