Transiting through LHR to Rome

I haven't seen this topic since Italy has changed it's quarantine requirements at the beginning of September for those traveling or transiting through the UK.

First, we cannot change our flights. They were booked through our mileage plan and British Airways was the only option for us if we needed to fly business class, which was imperative due to my back condition.

My husband and I are scheduled to fly from Denver to LHR on October 10th which arrives on October 11th, with a 4 hour layover before connecting to our flight to Rome. We arrive in Rome on October 11th @ 7:25pm.

As far as the Covid-19 test, my question concerns the 48 hour rule for those transiting from the UK to Italy. I have seen it described 2 different ways. 1) 48 hours is calculated based on your originating airport departure flight (the USA), i.e. 10/10. And, 2) According to the Italian "Ministry of Foreign Affairs" Covid-19 survey website, the test must be done within 48 hours prior to arrival in Italy. So which is it?

Who checks the Covid-19 test results? Is it the originating airport, passport control in Rome or somewhere in between?

Between the 9 hour flight from Denver-London, 4 hour layover in Heathrow and 2 hour flight to Rome, travel time is over 15 ours from departure, plus time change of +8 hours.

Right now we are scheduled to get an antigen test by my primary care doctor on 10/8. But because I am concerned about this 48 hour rule, I am also going to schedule the Walgreens ID Now Rapid Test on 10/9 as well. They are saying you get the results in 24 hours which is the date of our departure. This obviously cuts things very close, hence, my nervousness.

So does anyone have practical experience or more insight about this rule?

Sorry for such a long post but I can't seem to find out much more information so to be absolutely safe I am inclined to go with the "48 hours prior to arrival in Italy" statement unless someone here knows exactly how this works.

If Italy accepts an antigen test, you could use the proctored Emed Abbott self-test kits. We used these for the way home to the US, and it was an easy process. Not sure if anyone has used them as entry to a country.

First, do not complicate things by trying to add in the time change. Basically, if you started a timer at the time you take the test, in 48 hours, will you be in Rome? The timer does not gain or lose time based on where it is.

Second. In Italy, it is unlikely anyone will ask for results. You will need them if asked, but I have not yet seen anyone say their test results were asked for. The Airline is responsible for verifying the results, so in Denver, BA will look at your tests, but to be honest, I am not sure if they will apply the 72 hours that Italy requires of the US, or catch that since you are transiting LHR, you need 48 hours. You may also need to show them to board the fight at LHR to Rome.

So if you consider 7:25 PM in Rome is 11:25 AM in Denver, your timer would hit 48 hours exactly if you were tested on 10/9 at 11:25 AM. So you should get the Walgreens Antigen test after that time. Talk to your local Walgreens and find out if an appointment is available, if so, ask them what their test time is. Walgreens offers the 24 hours as a Guarantee, but actual results should be sooner, ours were complete in about 2 hours, the store should be able to tell you what they typically see...but you will need the results prior to boarding. If that does not work, someone in Denver likely does the test essentially "while you wait" either at the airport or at a Lab. Proctored test over video is another option. In all cases, verify with BA what tests they accept, some airlines only allow specific ones, but they should also communicate that to you.
