eDNA in Water Testing
Our Environmental DNA (eDNA) water testing services deliver accurate, science-based insights that help protect ecosystems and support informed conservation efforts. Whether you're monitoring sensitive species, tracking invasive organisms, or assessing ecosystem health, our eDNA solutions make it simple to gather the data you need. Technical notes and analysis request forms in relation to eDNA water testing can be found here.
What is eDNA?
eDNA can be defined as ‘genetic material obtained directly from environmental samples without any obvious signs of the biological material’. All organisms (bacteria, fish, invertebrates, etc.) shed DNA into the environment.
Why use eDNA testing?
eDNA testing offers a non-invasive way to detect which species are present in a freshwater environment—without the need for disturbing it. It’s a powerful method for assessing biodiversity and ecosystem health, providing insights that traditional monitoring methods may miss.
While eDNA has many advantages, it’s important to understand its limitations and the factors that can influence results. For a detailed overview of the strengths and considerations of eDNA testing, check out our Technical Note outlining key benefits and limitations.
How do I order a sampling kit?
We offer easy-to-use sampling kits designed for both single and replicate analyses, backed by fast, reliable lab processing. To order a kit, please contact our environmental client services team at env.csm@hill-labs.co.nz.
How do I collect eDNA samples?
Please follow our guide to collect your samples. Our Water eDNA Test Kit instructions can be found here.
How long will it take to get my results?
We aim to report eDNA results within 10 working days following day of receipt at the laboratory.
How will my results be reported?
Hill Labs eDNA results are reported in three separate csv files, along with a summary pdf report. Example CSV files are shown below:
1) detailed results
2) summary results
3) sample metadata (GPS coordinates, volume of water filtered, sample collection site, index scores etc.)
If any ‘flagged’ organisms are identified in a sample, a fourth csv entitled ‘eDNA-Flagged’ will also be reported.
