Abstract
The invention provides novel haptens and immunogens for the preparation of novel monoclonal antibodies, which detect the synthetic opioid meperidine and its active metabolite normeperidine. These antibodies enable methods and kits, which are useful in an immunoassay for therapeutic drug monitoring (TDM) and in extending the window of detection for cases of abuse and drug-facilitated sexual assault (DFSA).
