In many countries, access to this form of testing has been challenging. A new technology for COVID-19 detection has become available that is much simpler and faster to perform that currently-recommended nucleic acid amplification tests (NAAT), like PCR. This method relies on direct detection of SARS-CoV-2 viral proteins in nasal swabs and other respiratory secretions using a lateral flow immunoassay (also called an RDT) that gives results in < 30 minutes. Though these antigen detection RDTs (Ag-RDTs) are substantially less sensitive than NAAT, they offer the possibility of rapid, inexpensive and early detection of the most infectious COVID cases in appropriate settings.20 pagesenBrac University theses are protected by copyright.
