While you may be used to thinking of COVID tests as interchangeable, there’s a big difference between the standard at-home antigen test and a PCR or other type of molecular test. Almost five ...

First developed more than four decades ago as a biological research technique to amplify nucleic acids, polymerase chain reaction (PCR) technology still has untapped potential, with many exciting ...

But what is real time RT–PCR? How does it work? How is it different from PCR? And what does this have to do with nuclear technology? Here’s a handy overview of the technique, how it works and a few ...

Polymerase chain reaction, or PCR, is a laboratory technique used to make multiple copies of a segment of DNA. PCR is very precise and can be used to amplify, or copy, a specific DNA target from a ...

A polymerase chain reaction (PCR) test can be positive for up to 90 days after infection. The discrepancies between tests and the lengths of their positive results boil down to what each test ...

Since the emergence of COVID-19 in late 2019, the gold standard in testing for the disease has been a nuclear-derived technique: real-time reverse transcription–polymerase chain reaction, or real-time ...
