Why is the university using the saliva test instead of the nasal swab test?

Campus added Shield’s saliva-based COVID-19 testing in order to increase our testing capacity. Our nasal swab capacity is about 12,000 tests per week. Our saliva-based testing adds up to 70,000 tests per week. We will continue to perform nasal swab tests in addition to saliva tests, predominantly for students living in our residence halls. Using both approaches, we are able to test many more people much more frequently. Both tests are highly accurate PCR-based tests, the gold standard for COVID-19 diagnosis.
