Two types of COVID-19 tests, the rapid antigen test and the polymerase chain reaction (PCR) test, are available in the United States. The PCR typically relies on lab testing and is still considered ...

Rite Aid is joining forces with Quest Diagnostics to provide access to molecular testing (polymerase chain reaction or similar nucleic acid amplification test) to help Rite Aid customers detect and ...

There are three different ways to test for COVID-19: PCR tests, antigen tests and antibody tests. Each method is best for a different stage of COVID-19 infection. Used in sequence, all three methods ...

Polymerase chain reaction (PCR) and rapid (antigen) tests for COVID-19 both involve taking a swab. Results for a PCR test take longer, as it needs to go to a laboratory. It is more costly but tends to ...

Researchers have built an RT-PCR platform that gives results in 23 minutes that match the longer laboratory-based tests -- faster than other PCR tests on the market. It can be adapted to test for a ...

Remember that the RT-PCR test is just one part of how to diagnose and treat a patient with suspected COVID-19. It is important to look at the rest of the patient’s laboratory results and their images.

For more than 30 years, polymerase chain reaction (PCR) has been the gold standard in molecular diagnostic testing, detecting genetic material, such as those from a virus or from human DNA. But PCR, ...
