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. PCR tests work by directly detecting the viral genetic material (RNA), Antigen tests work by detecting specific proteins on the surface of the virus, PCR test results can take from hours to up to one week, Antigen test results are available in less than one hour, PCR tests have a lower chance of false-negative results (a false negative means the test does not detect COVID even though the patient has it) and are more accurate, Antigen tests have a higher rate of false-negatives. Some tests provide results rapidly (within minutes); others require 1-3 days for processing. Tests vary in their sensitivity (i.e., few false-negative results or few missed detections of SARS-CoV-2) and specificity (i.e., few false-positive results or few tests incorrectly identifying SARS-CoV-2 when the virus is not present). For more information about COVID-19 vaccines and antibody test results, refer toInterim Clinical Considerations for Use of mRNA COVID-19 Vaccines Currently Authorized in the United States.
