What is an at-home rapid antigen test, and how does it differ from a PCR test? Most at-home tests are rapid antigen tests that look for specific proteins of the virus to detect infection.

At-home rapid tests for COVID-19 are more convenient. But experts say there are still times when a PCR test is useful.

People who test positive for COVID-19 on a rapid test after five days of isolation are probably still infectious and should continue isolating, experts say. Though PCR tests are known to pick up ...

All at-home tests are antigen tests. PCR tests look for the genetic material of the COVID-19 virus and are considered the most reliable way to test for COVID-19, according to the state.

Respiratory syncytial virus (RSV) was detected easiest when using reverse transcription polymerase chain reaction (RT-PCR) tests in a pediatric population.

What does it mean when you have two lines on an antigen test and the one indicating COVID is very faint?
