Rapid tests can be taken and viewed at home, like with the Ellume COVID-19 Home Test, while several airlines offer passengers both at-home and in-person testing options at airports. NAAT uses different genetic material amplification techniques such as polymerase chain reaction, strand displacement amplification, transcription-mediated amplification, ligation chain reaction, and branched DNA reaction (quantiplex b DNA). Antigen tests detect specific proteins on the surface of the virus. CDC twenty four seven. Using the search box in the EUA tables, you can use keywords to search and filter the type of test or collection kit you are looking for.
