Standard for Evaluation of Measurement Uncertainty in Forensic Toxicology

This document provides minimum requirements for evaluating measurement uncertainty for quantitative forensic toxicology testing activities as well as calibration of breath alcohol measuring instruments. Specifically, it is intended for the subdisciplines of postmortem forensic toxicology, human performance toxicology (e.g., drug-facilitated crimes and driving-under-the-influence of alcohol or drugs), non-regulated employment drug testing, court-ordered toxicology (e.g., probation and parole, drug courts, child services), and general forensic toxicology (non-lethal poisonings or intoxications) as well as calibration of breath alcohol measuring instruments.

It does not address evaluating measurement uncertainty for breath alcohol subject testing, nor does it address uncertainty or performance measures for qualitative forensic toxicology testing activities.
