The University of Arizona will require students who live in dorms or attend in-person classes on the main campus to be tested weekly for COVID-19 in the spring. The university also will begin offering a new swish-gargle PCR test in addition to nasal swab antigen and PCR testing in the spring. The new test developed by a team of UArizona researchers lead by Dr. Michael Worobey, UArizona EEB department head and BIO5 institute associate director, involves swishing and gargling a saline solution, then spitting into a tube. Results are usually available the same day.
