- Quantifying the Detection Sensitivity and Precision of qPCR and ddPCR Mechanisms for eDNA Samples. Guri, Gledis Ray, Jessica Louise Shelton, Andrew Olaf Kelly, Ryan P Præbel, Kim Andruszkiewicz Allan, Elizabeth Yoccoz, Nigel Johansen, Torild Wangensteen, Owen S Hanebrekke, Tanja Westgaard, Jon-Ivar Environmental DNA (eDNA) detection employing quantitative PCR (qPCR) and droplet digital PCR (ddPCR) offers a non-invasive and efficient approach for monitoring aquatic organisms. Accurate and sensitive quantification of eDNA is crucial for tracking rare and invasive species and understanding the biodiversity abundance and distribution of aquatic organisms. This study compares the sensitivity and quantification precision of qPCR and ddPCR for eDNA surveys through Bayesian inference using latent parameters from both known concentration (standards) and environmental samples across three teleost fish species assays. The results show that ddPCR offers higher sensitivity and quantification precision, particularly at low DNA concentrations (
