Fit to travel PCR tests

[holidayquerie]

Hi all,

I'm going to Dubai at Christmas and need a PCR test within 72 hours of departure. I live in Cornwall and I'm wondering what company is the best to go for. A few I've seen, they post the PCR tests to you and then you return them to a drop box or similar, those that I've looked at don't have any in Cornwall, the closest one is Plymouth,

So AIBU to ask for recommendations of how to go about sorting this? I'm overwhelmed with it all! Please help :) x

Where are you flying from? People I know in Cornwall just drop them off at Exeter airport on their way back. Nobody seems that bothered about correct time frames etc.

Flying from Heathrow to Dubai. I need the test within 72 hours before I travel, so I need to do one before, as well as on the way back
