Urine Drugs of Abuse Screening and Quantitation


Many clinical laboratories processing large number of samples in a limited time frame require minimal preparative steps to reduce time and cost. In a poster at SOFT 2015 presented by a pain medication monitoring laboratory, the researchers reported a LC-QTOF MS method with minimal sample processing steps.

 A critical component of this dilute and shoot method was the genetically modified beta-glucuronidase, IMCSzyme®, which has higher purity than other commercially available beta-glucuronidases, which translates to no interferences identified on the LC-QTOF-MS.

This study highlights the application of a LC-QTOF MS as a sensitive, selective and reproducible solution for quantitation of drugs in urine samples that was achieved using the genetically modified beta-glucuronidase, IMCSzyme®.
