Why did the home antigenic coronavirus tests come out negative and the PCR test positive?
Yesterday I had a covid test done at a swab point with a referral from a doctor/positive result/quarantine 10 days. Today I did 2 tests at home. 1.Mila Covid 19 rapid antigen test with saliva and 2.Covid-19-Checki-1 rapid test in nasal swab samples. Both with negative results. How is this possible?

For @Miki: In this case, you may suspect incorrect material collection when performing a PCR swab. It is quite doubtful that all antigen tests indicated a false positive result.
And what about the other way around? I did two different cassette tests every day for five days and the results were always positive (10 tests) while the PCR test on the second day was negative?

Taka sytuacja jest możliwa wówczas, gdy domowy test antygenowy zostanie wykonany zbyt wcześnie. Aby taki test był wiarygodny, należy wykonać go nie wcześniej, niż w 3 dniu objawów (najlepiej w 5-7 dniu od zakażenia).
Można zatem przypuszczać, iż domowe testy zostały wykonane zbyt szybko.
