Abstract
The immunoassay method and kit are provided for the detection and/or the determination of zolpidem. The disclosure provides novel antibodies, derived from a novel immunogen, that are highly sensitive and bind to zolpidem and its main urinary metabolite [3-(2-N,N-dimethylamino-2-oxoethyl)-6-methylimidazo[1,2-a]pyridin-2-yl]benzoic acid, enabling an extension of the detection window of zolpidem in individuals who have abused the drug, or have been victim of its side-effects or its criminal misuse.
