Dr. KC Coffey, Epidemiologist at the University of Maryland School of Medicine, discusses the differences between PCR Covid testing and rapid testing.

As cases continue to rise, here’s a refresher on the two types of viral tests you can take if you believe you’ve been exposed to COVID or are experiencing symptoms.

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

At-home tests and the omicron variant When the omicron variant emerged in late November 2021, scientists quickly responded to determine how PCR and rapid tests performed against this new variant.

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

When you think about getting tested for COVID-19, you’re most likely picturing two types of tests: the at-home rapid antigen tests you can buy at the drugstore and the PCR test where the results ...

At-home tests and the omicron variant When the omicron variant emerged in late November 2021, scientists quickly responded to determine how PCR and rapid tests performed against this new variant.

The two main options for at-home COVID-19 testing today are rapid antigen tests and those based on reverse transcription polymerase chain reaction (RT-PCR).

Experts say rapid home tests still work to detect the latest variants of the virus that causes Covid-19, but how and when home tests are used has changed.

The discrepancies between tests and the lengths of their positive results boil down to what each test looks for and how sensitive it is. PCR tests are highly sensitive and are good at detecting ...

One of the key strengths of this study design is to provide detailed insight into the symptom burden and QoL before, during, and after a positive and negative COVID-19 PCR test.
