When faced with the need to get a COVID test, it's important to know that not every test is created equal, with different levels of accuracy as well as the time it takes to get results back. Some countries will only accept RT-PCR tests — considered the most accurate — while others will accept proof in any form of negative test to enter.

All viral tests detect a current infection and are most accurate when "the person is tested when viral load is generally highest," the CDC explains. Many states and countries mandate travelers get tested before and after a trip, while some places require testing to attend things like sports games or a concert.

This test also uses NAAT, but is run "at or near the place where the specimen is collected," providing quicker results, according to the CDC. These are at-home or point-of-care tests that provide results typically within about 15 minutes, according to the CDC. These tests are often performed with a nose swab, which is then placed directly into an extraction buffer or reagent.

While many countries require PCR tests to enter, some allow for rapid antigen tests in their place, including Jamaica and Belize. Additionally, while the CDC requires all international travelers to get a test within three days of boarding a flight to the U.

Rapid tests can be taken and viewed at home, like with the Ellume COVID Home Test , while several airlines offer passengers both at-home and in-person testing options at airports. Antibody tests are unique from viral tests in that they do not detect a current infection.
