WebTo improve this situation, an optimized droplet digital PCR (ddPCR) was used for detection of SARS-CoV-2, which showed that the limit of detection of ddPCR is significantly lower than that of RT-PCR. We further explored the feasibility of ddPCR to detect SARS-CoV-2 RNA from 77 patients, and compared with RT-PCR in terms of the diagnostic ... WebFeb 13, 2014 · There have been a few other reports mentioning false-positive droplets in ddPCR at low ranges of detection, De Spiegelaere said. A seminal HIV DNA study in PLOS One by Matthew Strain at the University of California, San Diego, showed increased precision of ddPCR over qPCR on a set of 300 patient samples. That work also …
