PCR tests, which are processed in a laboratory, use a molecular technique and can detect even trace amounts of virus.

The regulator also directed all airlines operating to and from Pakistan to ensure that all passengers travelling to the country possess test results from government-approved labs and that no test results be accepted without a valid QR code. “Only original reports are accepted prior to checking in passengers for flights and no copies are accepted.
