Antigen and Molecular Tests

Posted on | Posted on John Murphy | Leave a Comment on Antigen and Molecular Tests

Diagnostic tests are used to detect current, active infections of the SARS-CoV-2 virus. Diagnostic tests can be antigen based (“rapid antigen” tests), which look for protein markers on the outside of the virus, or they can be molecular based (including PCR, LAMP, CRISPR), which look for viral genomic material specific to SARS-CoV-2. Molecular based tests that amplify […]

Authors: Myron S. Cohen, M.D. Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), the virus that causes coronavirus disease 2019 (Covid-19), has generated a worldwide pandemic. The interruption of its spread depends on a combination of pharmacologic and nonpharmacologic interventions. Initial SARS-CoV-2 prevention includes social distancing, the use of face masks, environmental hygiene, and hand washing.1 Although […]
