In Vitro Diagnostics for COVID-19: State-of-the-Art, Future Directions and Role in Pandemic Response
There have been tremendous advances in in vitro diagnostics (IVD) for coronavirus disease 2019 (COVID-19) caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). Although the confirmatory clinical diagnosis is made by real-time reverse transcriptase polymerase chain reaction (RT-PCR), lateral flow immunoassay (LFIA) based viral antigen (Ag) detection is used for mass population screening at point-of-care (POC) settings. The rapid RT-PCR tests (such as from Cepheid and Bosch) have an assay duration of less than 40 min, while most rapid Ag tests (such as Abbott’s BinaxNOW™ COVID-19 Ag card) have an assay duration of about 15 min. Of interest is the POC molecular test (ID NOW™) from Abbott that takes less than13 min. Similarly, many immunoassays (IAs), i.e., automated chemiluminescent IA (CLIA), manual ELISA, and LFIA, have been developed to detect immunoglobulin G (IgG), immunoglobulin M (IgM), and immunoglobulin A (IgA) produced in subjects after SARS-CoV-2 infection. Many IVD tests have been approved by the United States Food and Drug Administration (FDA) under emergency use authorization (EUA), and almost all IVD tests are Conformité Européenne (CE) certified.
