How does Environmental DNA work and what are the advantages of eDNA testing?

Modified on: Fri, 21 Dec, 2018 at 12:37 PM

Environmental DNA (eDNA) testing is cost effective, more accurate than traditional methods, has less risk of pathogen transfer, and is less invasive to species (especially at-risk species) and ecosystems. 

The eDNA tests can be performed for multiple species using a single sample and it provides early detection of invasive species. This molecular biology method detects DNA of target species through quantitative polymerase chain reaction (qPCR) using the TaqMan® Assay.
