ROCHESTER, Minn. — Minnesota Governor Tim Walz recently announced that any Minnesota resident who participated in a protest, vigil, or other mass gathering, including first responders, are eligible to receive a COVID-19 test. Mayo Clinic and Mayo Clinic Health System sites in Minnesota are helping to support public health departments in local communities and have implemented new testing guidelines to ensure increased access to testing.
Elitza Theel, Ph.D., Laboratory Director of the Infectious Diseases Serology Laboratory at Mayo Clinic, led the efforts to evaluate and implement the serologic antibody test for COVID-19. She gives an overview of Mayo Clinic’s COVID-19 antibody test, as well as the role of antibody testing during the pandemic, and how sensitivity, specificity, and prevalence play a large role in the positive predictive value of a test.
