Germany's Frankfurt Airport, the country's largest, has opened its own testing center for passengers.

The center, opened in cooperation with airport operator Fraport, airline Lufthansa and biotech firm Centogene, offers several different tests as part of its efforts to help passengers avoid a period of quarantine at their destination.

The tests include a standard one, which costs 59 euros ($66), and will take six to eight hours to get the result and a fast-track test, which will take only two to three hours for a result.

Arndt Rolfs, CEO of Centogene, explained the concept: "I have to get on a flight in a few hours, or I am taking part in an event. I come to the test center, I register through the app, which is very user-friendly, I am handed a test kit and then experienced medical staff take a sample. This takes about three or four minutes altogether." 

He added: "Sometimes registration is the most difficult part. Then the samples are processed directly in the truck, in about three or four hours, 98 percent of the test results are sent to the passengers through the app, meaning they are digitally uploaded through the app."

Travelers will be able to take a test the day before, or the day of travel, at a building close to the airport's main terminal. 

The center, which has capacity to carry out 5,000 tests per day, is expected to run until at least 31 July 2021.
