For people who have returned to the U.S. from abroad, what did you use for a COVID test? I've read some trip reports, it seems many have been using antigen tests you ordered and brought with you on your travels.
The antigen test tends to be a fair amount cheaper and faster, often within 15 minutes. From what I know, there is a higher potential for false positives with this test. (Still a fairly low percentage of total tests) I have heard suggested that if you have a positive on an antigen test you could then do a pcr test, I'm assuming that the person would need to quarantine until the pcr test result is ready.
There have been some problems with the "mail order" antigen tests. I read a few have spoiled a test and needed to use another one. (or maybe it was defective in the first place) I have also read that there can be long hold times and very good wifi is necessary for the process.
PCR tests seem to cost at least 3 times more than an antigen test and can take 24 hours or longer. It is my understanding that they are more accurate than antigen tests.
I've heard of people doing both tests, the antigen as kind of insurance in case the pcr takes too long. I wondered what would happen if there were differing results.
Obviously, prices differ by manufacturer and city/country. Also, it has seemed that the availability of tests either as walk up or by appointment, varies by country.
I am considering travel in a few weeks (Poland) and I'm trying to decide what type of test works best for us. I have been in contact with the BnB we would stay at in our departure city to discuss test availability.
