Here is my experience on September 5th - I was worried that the Abbott ID NOW test would be disallowed.
I ended up getting a Rapid Antigen test and did a lot of research to find that the Quidel Sofia FIA test that was one of 3 options offered by a nearby testing service. I stopped by the test site before getting the test to insure that this was the test they would be using. When I got my test result back, it showed the use of the CareStart test which did NOT appear to qualify according to EU standards and the EU list.
I was concerned that it would be checked by TAP Air Portugal when I checked in on September 6th and I was prepared to get another test at a cost of $200 or so, this time a RT-PCR at San Francisco airport if need be and I was able to succeed in getting the test in a short time window between when they checked my docs and the check-in cutoff time.
I was also prepared to abort the trip at the airport if I had to.
Turns out that TAP did not closely check the details of my Rapid Antigen test and issued my boarding pass without question.
I was still a little concerned that on arrival in Lisbon that it would be checked there for conformance and then I might need to get another test at the Lisbon airport but at least I would be there and they were unlikely to turn me around.
Customs in Lisbon glanced at the document but did not even take a close look at it. I was not given a temperature check or anything like that. No problem getting through customs.
I had closely timed my 48 hour test so that it would also cover me for hotel check-in in LIsbon with about 3 hours of tolerance. The hotel said that I could either show proof of vaccine (which I had) and so they did not even look at my Covid test report.
Based on my experience, I suspect that the Abbott ID Now test would work fine even though that is not the test I ended up getting.
Your results may vary. I stressed out a lot about which test and it turned out not to make much if any difference so long as you are within the 48 or 24 hour window depending on whether it was a Rapid Antigen or a NAAT test.
Hope this helps someone else. Good travels!
