Q: In most cases, we will repeat the RT-PCR test on the assumption that the original test was conducted too soon or got contaminated. Adding the PCR antibody testing could tell us a little more about ...

Reverse transcription polymerase chain reaction (RT-PCR) has served as the cornerstone of SARS-CoV-2 diagnosis since the earliest stages of the COVID-19 pandemic. The technique’s capacity to amplify ...

According to WHO, it can be difficult to clinically distinguish Ebola disease from other infectious diseases such as malaria, typhoid fever, shigellosis, meningitis and other viral haemorrhagic fevers ...

We conducted a phase 2–3 double-blind trial to assess the efficacy and safety of nirmatrelvir–ritonavir in asymptomatic, rapid antigen test–negative adults who had been exposed to a household contact ...

Syndromic reverse transcriptase–polymerase chain reaction tests for respiratory infections were associated with lower health care resource utilization and costs, implicating potential for improved ...

In a recent study published in Lancet Microbe, researchers compare the potential of real-time reverse transcriptase-polymerase chain reaction (RT-PCR) genotyping assays with whole-genome sequencing ...

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 ...
