Consolidating LC-MS/MS Method Conditions for the Analysis of Alcohol Metabolites, Barbiturates, and Drugs of Abuse

22 Jan 2026

Efficiency is key in toxicology laboratories where multiple drug panels must be run daily. Consolidating multiple drug panels into large, multi-class drug assays can streamline the analytical testing process and reduce operating costs. To simplify the analysis of alcohol metabolites, barbiturates, THC metabolites, and drugs of abuse, three different LC-MS/MS methods were developed for each analyte class using the same analytical column and mobile phases.

A panel of 100 drugs of abuse, novel psychoactive substances, therapeutic drugs and metabolites, a panel of biomarkers of alcohol consumption, and a panel of barbiturates and cannabinoid metabolites were all analyzed using the same analytical column and mobile phase set up.

This work highlights the ability of one LC-MS/MS setup to analyze multiple toxicology panels. This allows for laboratories to simplify testing procedures, save time, and reduce operating costs.
