Covid Rapid Antigen Testing

This video explains the mechanism of lateral flow assays in Rapid Antigen Tests used in the diagnosis of SARS-Cov-2 infection and examines the advantages and the disadvantages of rapid antigen testing compared to RT-PCR tests and NAAT testing modalities. A detailed explanation of how and which antigens are tested for the diagnosis. The significance of positive and negative results is reviewed and the course of action as recommended by the FDA is mentioned. Viewers are given brief definitions of sensitivity and specificity and the different applications and suitability of the Lateral flow technology for the rapid antigen testing and diagnosis of COVID-19 is discussed. By the end of the video viewers should clearly understand how the rapid antigen test is used to diagnose COVID-19 and its importance as a tool in the armamentarium of instruments available for he fight against SARS-CoV-2. Viewers will know what a rapid antigen test is and what lateral flow assays are. They will understand how and when a rapid antigen test should be employed and what actions to take depending on the result obtained from testing.
