To do this, the researchers administered both the rapid antigen and PCR detection methods to just over 6,000 people who came to the Baltimore field hospital for COVID testing between Dec. 23, 2020 ...

Three studies used a digital droplet PCR (dd-PCR) for good-level detection of the SARS-CoV-2 genome. However, the specimen type was mostly not semen for this process as well.

RT-PCR detection systems rely on adequate viral load at the sample collection site. When the viral replication time-window is missed, it leads to an increase in false-negatives.

An optimized PCR approach integrates: Quantitative thresholds aligned with clinical infection definitions. Correlation with patient symptoms to avoid unnecessary treatment. Detection of resistance ...

Dogs can be trained to sniff out COVID-19 cases. They’re overall as reliable as PCR tests and even better at IDing asymptomatic cases, a study suggests.
