ABSTRACT:
The invention provides an immunogen comprising a hapten coupled to an antigenicity-conferring carrier material, a conjugate comprising the aforementioned hapten coupled to a labelling agent, as well as, antibodies raised against the aforementioned immunogen and capable of binding with at least one structural epitope of metabolites of fentanyl and of metabolites of fentanyl analogs.
