Rapid antigen testReal-time reverse transcription-polymerase chain reactionCroatiaBACKGROUND The global outbreak of coronavirus disease 2019(COVID-19)leads to the development of accessible and cost-effective rapid antigen-detection tests(RATs),as quick and accurate diagnosis is crucial to curb the ...
Rapid antigen tests, which you can buy in most pharmacies, are great in specific circumstances and less good in others. Rapid antigen tests detect COVID-19 when people have a higher amount of virus particles in their system and are more contagious. But a negative antigen test doesn't necessa...

Everything you need to know about at-home rapid Covid tests. How accurate they are, which to buy, and when to take the test for the most accurate results.
Rapid antigen tests are an attractive option because in addition to their speed, they are cheap and easy to produce and therefore more broadly available than the more commonly used gold-standard PCR tests in theory. But these attributes come with a trade-off:less diagnostic accuracy. This makes...

Antigen tests may be less accurate Antigen tests, more commonly known as rapid tests, pick up the bits of proteins on the virus’s surface which are known as antigens, according toCleveland Clinic. These tests are referred to as “rapid” because results are ready in just 15 to 30 minutes...
When a positive rapid antigen test goes from a dark line to a very faint line, this means that the virus load in the swab is probably less than when then line was dark, he adds. “So even a faint line after a really dark line means you are likely much less contagious, and no line...
We soon understood that aPCR testcould detect even small amounts of the virus'geneticmaterial, meaning it could remainpositivelong after theinfectionhad passed.Rapidantigen-basedtests can detect thepresenceof viral(病毒的)protein...
result from a rapid test with a RT-PCR test, particularly where cases of COVID-19 are low, may help avoid unnecessary quarantine. All antigen tests will miss some people with infection, so it is important to inform people who receive a negative test result that they may still be infected...
