Tests (assays)

Each test (assay) is designed to detect a particular group of species, or just one single species.

Those that target groups of species, e.g. ‘fish’ or ‘mammals’ are referred to as multi-species (metabarcoding) tests.

Those that target one single species, e.g. European eel, or zebra mussel, are referred to as single-species (qPCR) tests.
