The COVID-19 pandemic led to many changes. Among them is universal familiarity with a molecular diagnostic technique that was largely unknown outside clinical use. The polymerase chain reaction — or ...

When COVID first hit, waiting days for laboratory results from an ultrasensitive polymerase chain reaction (PCR) test was commonplace. Faster tests usable by anyone, anywhere, later became widely ...

Over the past four years, many of us have become accustomed to a swab up the nose to test for COVID-19, using at-home rapid antigen tests or the more accurate clinic-provided PCR tests with a longer ...

Polymerase chain reaction (PCR) is a fundamental molecular biology tool that scientists use to amplify and analyze genetic material, such as DNA and RNA. PCR involves the enzymatic amplification of ...

The ongoing hantavirus outbreak carries disturbing echoes of the early days of COVID: people falling ill on a cruise ship from a relatively unknown pathogen, with no validated test available to ...

A new diagnostic tool developed by researchers can test for SARS-CoV-2 and Zika virus with the same or better accuracy as high-precision PCR tests in a matter of hours. Over the past four years, many ...
