African clawed frog
The African clawed frog (Xenopus laevis) is an invasive amphibian species in the UK, originally introduced in the 20th century through the pet trade and its use in pregnancy testing before modern methods. Native to sub-Saharan Africa, this aquatic frog is highly adaptable and can thrive in a variety of freshwater habitats, including ponds and slow-moving streams. While its UK populations are limited, X. laevis poses ecological risks, as it is a voracious predator of invertebrates and small vertebrates, potentially disrupting native ecosystems. Additional it is a known carrier of the chytrid fungus (Batrachochytrium dendrobatidis), which has contributed to amphibian declines globally. Conservationists monitor its presence to mitigate its ecological impact.
eDNA testing (environmental DNA testing) offers a non-invasive method to detect Xenopus laevis populations. By analyzing water samples for genetic traces shed by the amphibian eDNA testing provides a highly sensitive and specific tool to confirm the presence of this species without the need for traditional visual surveys.

How does it work?
Step 1: Buy your sampling kits in the Shop
Our sample collection kits ensure the DNA in your samples is preserved and protected during transit to our laboratory. We have kits for water, soil, scat and more.
Step 2: Collect your samples
Our molecular ecologists can advise you on sampling strategies and how to make the most of your budget
Step 3: Order your testing in the Portal
Register your samples online. Tell us which tests you want to order for each sample. Return the samples to us. We invoice you for the testing upon completion (we do reserve the right to charge for testing upfront if it is your first order). Alternatively, you can email your testing order to our team using the email in your kit.
Step 4: Receive your results
Your results will be sent to our secure online portal. If you need it, we can offer a free consultation to help you interpret your results.
