Frequently asked questions

 
 

  • Once shed from an organism, eDNA will remain around for a few hours to a few days.

    Biological and environmental factors degrade eDNA. The rate at which this occurs depends on whether the eDNA is in freshwater, marine water, stagnant water, or flowing water etc.

  • Sample during low rainfall periods or in places where there has been less than 10 mm of rainfall in the last 24 hours.

    Rain can dilute the DNA in the water as well as disturb sediment that can in turn clog the filters.

  • Not necessarily.

    We recommend that the eDNA results get used as a detection or presence/absence tool. There are various factors that can determine the quantity of DNA detected.

  • From the receipt of samples into our lab (if the samples have been submitted online), it takes on average 2-3 weeks for your results to be sent to you.

    Occasionally, samples may take slightly longer due to seasonal surges.

  • No, but in most cases we would highly recommend completing a chain of custody form.

    It is helpful for us if you include a chain of custody form with your samples as our sample receipt team will be able to efficiently identify the job number the samples are associated with. A chain of custody form will be sent to your supplied email after submitting your samples.

    Chain of custody forms are a regulatory form and are only really needed if you’re doing work for someone else. For example, if you are a consultant doing some sampling for a council or if the results could end up being used as evidence in environment court.

  • Absolutely.

    While our kits are designed for freshwater environments, they can be used in marine environments. Please reach out to us with your requirements and we will see how we can help.

  • Wilderlab removes all human DNA as a first step when processing samples.

    It is impossible for us to detect individual people.

  • We recommend passive samplers for flowing sites with very high sediment load, post rainfall sampling, and pest mammal monitoring.

  • Standard syringe kits with a 1.2 µm filter are suitable for most applications. Wetland kits have a 5.0 µm filter that are less prone to clogging in higher sediment or turbid environments.

  • Samples can last at room temperature for up to 6 months after the preservative has been added (included in all sampling kits).

    For long term storage it is recommended to freeze the sample.
