A rapid antigen test for travel may be a necessary requirement if you are planning to travel abroad very soon. A rapid antigen test detects easy-to-find surface markers on the outside of the virus and avoids extraction and amplification steps. The samples are usually collected from easy-to-reach areas where the virus tends to replicate the most. This method can detect active production of viral proteins, fairly rapid tests, and RNA extraction and amplification steps are not needed.
While the principles of rapid antigen test for travel remain similar, in that the test produces a quantifiable or visible change to signal a positive test result, there are different mechanisms by which tests can accomplish this as well as different ways in which the results can be read. One of the mechanism is the lateral flow assays which detects active infection through directional flow of patient sample over target proteins, usually on a flat card or cassette. Another mechanism is immunoassays which detects active infection through incubation of patient sample with test proteins, usually in a 96-well plate or similar. The two test mechanisms mentioned above take advantage of SARS-CoV-2 antigens binding only to specific human proteins. When this binding action happens during the test, a color or light change is produced that can then be read. There are a number of ways that rapid antigen test results can be read. One way is a visual read, which can be performed at home (either supervised or over the counter) or in a laboratory/healthcare setting. There is also the instrument read which must be performed in a laboratory or healthcare setting. Both methods have proven to be effective, so you can use any that you please.
