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.
