A PCR test is done to rule out that you have an ongoing infection with Covid-19. Nasopharyngeal sampling means a sampling stick with a cotton swab is taken and inserted at the back of the nose to the posterior pharyngeal wall. There, the stick is rotated for about five seconds against the mucous membrane. The sample is then sent encrypted to our partner's accredited security laboratory and analyzed. A negative PCR result (health certificate) is a security measure that the majority of countries require when entering today.
