The COVID-19 pandemic brought the term "Polymerase Chain Reaction testing" into the mainstream. The PCR method is a type of nucleic acid amplification test (NAAT) that detects a pathogen by finding ...

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 ...

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 ...

Because of its high accuracy, laboratory-based polymerase chain reaction (PCR) testing is the gold standard for infectious disease diagnostics. However, PCR technology requires highly trained staff ...

Respiratory syncytial virus (RSV) was detected easiest when using reverse transcription polymerase chain reaction (RT-PCR) tests in a pediatric population. Reverse transcription polymerase chain ...

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 ...
