  "term": "Proficiency testing",
  "field": "Chemistry",
  "definition": "The evaluation of a laboratory's performance against pre-established criteria by means of interlaboratory comparisons. This involves sending identical samples to multiple laboratories for analysis and comparing their results to a reference value or among themselves. It serves as an external quality assurance tool to assess the competence and reliability of analytical measurements.",
