Scoring and performance of analysis and interpretation of toxicologic cases assessed by external quality assurance.

摘要

Quantitative analysis of toxicology cases requires knowledgeable interpretation. We describe a scoring scheme that integrates analytical and interpretive performance for such cases using a reward/penalty scoring scheme. This scheme has been validated on cases circulated over the previous 5 years to volunteer participants in the UKNEQAS for Drug Assays Scheme. We have been able to identify a subset of poorly performing laboratories that should desist from toxicologic analysis and interpretation.
