When you arrive in the Dubai, there will be somebody directing you the PCR testing station. It's on the same level as arrivals.

As you're arriving in F, you may get a special fast-tracking. This was introduced last year.

When I did it back in December, we were one of the first flights to land in the evening bank, so there was only a small queue for tests. The whole thing only took 10 minutes. Other people have reported it can take 90 minutes at busier times - but arriving in F should negate any queues.

My results took around 24 hours to show on the App. Others have reported much reduced times - 4 to 6 hours seems normal.
