What are the PCR test requirements for Qatar Airways flights?

Travelers flying with Qatar Airways are required to have a PCR test conducted within 72 hours prior to departure. This has been confirmed by multiple users, although some mention a discrepancy with airline communications stating 48 hours. It is also noted that the test must be an RT-PCR type, while rapid tests may face additional scrutiny. For travelers from countries like the UK or Australia, timing of the test results can present challenges, especially with long-haul flights.
