If you recover from COVID and your symptoms come back within 90 days, don’t use a PCR test to see if you’re contagious again. Instead, choose an antigen test. If the result is negative, repeat it 48 hours later so you can trust the result. ...
DNA–protein crosslinks (DPCs) induced by aldehydes interfere with replication and transcription. Hereditary deficiencies in DPC repair and aldehyde clearance processes cause progeria, including Ruijs–Aalfs syndrome (RJALS) and AMeD syndrome (AMeDS) in
The role of precision medicine in advanced non-small cell lung cancer (NSCLC) has been continuously increasing in the latest years. The path to achieve complete molecular information is certainly long and challenging, as it is affected by the evolving and ever-changing nature of the neoplastic ph...
Q: How are rapid antigen tests different from PCR tests? Is one better than another? Rapid antigen tests, which you can buy in most pharmacies, are great in specific circumstances and less good in others. Rapid antigen tests detect COVID-19 when people have a higher amount of virus particl...

In short: any positive test counts as a positive, but a negative antigen test needs to be confirmed with a PCR test. Q: When should I use an at-home test? A rapid, at-home antigen test is a useful tool to have in your COVID-19 arsenal. But you need to know when and how to ...
At least one team played without their lab results, relying on last-minute negative results from rapid tests instead. But when they finally got their delayed PCR results from the state lab, one player tested "positive" with the state's highly sensitive test. ...
Library concentration, quality and fragment size were assessed by Qubit fluorometric quantification (Qubit dsDNA HS Assay Kit, Invitrogen, catalog no. Q32851), quantitative PCR and Fragment analyzer. Twelve multiplexed libraries were pooled and sequenced in one lane on the Illumina HiSeq4000 ...
16, looked specifically for the presence of the E gene subgenomic RNA by a PCR and took the presence of subgenomic RNA as an indication of active virus infection/transcription. That study could detect E gene subgenomic RNA at a level of only 0.4% of the virus genome RNA in sputum samples...
