VIRTUAL WORKING GROUP MEETING
Monday, July 26, 2021
1:15 - 3:15 pm
Presentations and Open Forum will discuss the optimal MS-based analyte identification criteria. A collaborative study of multiple matrices and analytes is being planned to evaluate analyte identification criteria to minimize the rate of false positives and false negatives.
Goals of the NACRW Veterinary Drugs Working Group
Reviewed study parameters, discussed introductory letter and "Call for Participants"; began developing a list of international laboratories who might participate; prepare protocol for first round.
