Polymerase chain reaction (PCR) test kits for COVID-19 use what’s known as gene cloning – not reproductive cloning – to detect the presence or absence of the SARS-CoV-2 virus, but social media posts ...

Genetic testing can be a fearful, daunting, overwhelming, exciting, or joyful experience. In many cases, the emotions of people who pursue genetic testing can be described with more than just one of ...

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 ...

Researchers have developed a light-induced DNA detection method that enables rapid, PCR-free genetic analysis. Their technique offers ultra-sensitive mutation detection in just five minutes, reducing ...

Because of the way the Omicron variant has mutated, some PCR lab tests can provide a good hint that it's around. The clue is not definitive, but it can help scientists determine which tests to ...
