COVID-19 Diagnostic Testing Redux (JCM ed.)

Laboratory testing for COVID-19, what’s new since we talked about this in August? A lot. Here are some of the questions we’ll talk about. • Do positive antibody tests indicate that people are immune to infection by SARS-CoV-2, the virus that causes COVID-19? • What sample types might replace the dreaded nasopharyneal swab for more comfortable sample collection? • What are the new rapid tests for COVID-19, and how should they be used? Alex is joined by two expert guests to discuss diagnostic testing for SARS-CoV-2. - Dr. Melissa Miller, who is the Director of both the Clinical Molecular Microbiology Laboratory and the Clinical Microbiology Laboratory at University of North Carolina School of Medicine. Dr. Miller is also an Editor of JCM. - Dr. Elitza Theel, who is the Director of the Infectious Diseases Serology laboratory at Mayo Clinic in Rochester, Minnesota. Dr. Theel is a member of the Editorial Board of JCM.
