And, by the way, the rapid antigen test he took when he got home that night was ... For a long time, we viewed COVID testing as something you do for your own health, but home PCR testing represents a ...

A recent real-world study that followed 30 subjects likely exposed to omicron found that PCR saliva tests can catch Covid-19 cases three days before rapid antigen tests, which use nasal swabs.

RSV tests include nasal swabs or blood tests to detect the virus's genetic material or antibodies, but rapid tests provide quick results.

The point-of-care tests are a fast and cheap, though less accurate, way of detecting the virus compared to sending nasal swabs to a lab. The rapid type of coronavirus test that Gov. Mike DeWine ...

How should we be using at-home rapid tests for omicron? Recent research indicates these nasal swab tests may be less sensitive to the coronavirus’ omicron variant in the earliest days of infection.

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.

Now we have access to PCR tests (known as RT-PCR, or reverse transcription-polymerase chain reaction, tests) and rapid antigen tests to detect SARS-CoV-2, the virus that causes COVID.

At-home COVID-19 tests have become commonplace for many households, but knowing when exactly to take a rapid test — or when to throw old ones out — isn't always straightforward. Here's what ...

Rapid tests work well on Omicron variants, but only if your viral load is high at the time. You need to reach a certain threshold before any test — PCR or rapid — can detect your infection ...

I had never taken a rapid test before, but the instructions were easy to follow. Rapid antigen tests are convenient, but they're not as sensitive as PCR tests.
