Covid-19 Detection Methods: A Review

Abstract

Coronavirus infection 2019 (COVID-19) diagnosis is crucial for prompt isolation of infected individuals and treatment of infected patients. Numerous methods exist for detecting COVID-19, including molecular testing or nucleic acid amplification tests (NAATs) and serological or antibody-based tests. NAAT detects the pathogen's genetic material, while serological tests detect antibodies. For the purpose of detecting COVID-19, radiological imaging of the lungs and viral antigen detection in vitro can also be used. This review article compares and contrasts several methods used to identify COVID-19 and discusses their respective merits and drawbacks.
