If you wait too long to check the result of a corona self-test, it can show a false-positive test result, according to the FHI.

“As a general rule, quick tests should be checked after 15 minutes have elapsed. Look at the instructions for use for the individual test, as this may vary somewhat,” Joakim Øverbø at the National Institute of Public Health (FHI) told the newspaper Dagbladet.

Øverbø says that if more than 30 minutes have passed since the test was taken, one can not trust the result.

“If it takes five minutes longer than the specified time, it will be ok, but if you wait much longer, you can get false-positive test results.”

In that case, the FHI recommends taking a new test.
