If you had COVID-19 symptoms in 2020, you probably would have masked up and braved a visit to a laboratory, doctor’s office, or clinic to get a polymerase chain reaction (PCR) test. A health care ...

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 ...

The question quickly arose whether existing rapid antigen tests could detect newly emerging variants. Using clinical samples obtained from diagnostic labs throughout the U.S. from 2020 to 2023, the ...

In a study involving nearly 1,000 patients seen at a Baltimore field hospital during a five-month period in 2022, researchers at Johns Hopkins Medicine, the University of Maryland School of Medicine, ...

For instance, if you only get a very faint line, it might be hard to know whether or not that means your results are positive. I know how that feels firsthand. After more than two years of evading ...

More people checking for Covid-19 infections are choosing rapid, at-home antigen tests over PCR tests processed at laboratories, making variant-driven waves harder to track and helping to spur a ...

Last spring, a rapid polymerase chain reaction (PCR) test for COVID-19 — developed by Northwestern University spinoff company Minute Molecular Diagnostics — received emergency use authorization (EUA) ...

For people with suspected community-acquired pneumonia (CAP) in the emergency department (ED), routine polymerase chain reaction (PCR) testing on lower respiratory tract samples led to faster and more ...

Northwestern scientists have created the fastest-ever hepatitis C diagnostic, delivering accurate results in only 15 minutes. The test uses the DASH rapid PCR system, originally developed for COVID, ...
