We just returned on Sunday. We did the deep nasal swab. Our tests say "PCR - Covid-19 Test - Final". While these test results were looked at upon arrival I would not say they were scrutinized. In my opinion they saw PCR and negative and stamped the results and we were sent on to immigration. It does not state on the test results that the method of collection was a deep nasal swab. That may be implied by the term PCR.
