Components of a Quality Assurance Program for Analytical Laboratories


The goal of any legitimate analytical laboratory is to produce, within its resources, the highest quality of analytical data possible that is accurate, precise, reproducible, defensible, and documented. How can the laboratory owner and the data user of that laboratory be assured that the results are as reported? While there is no absolute guarantee that data generated by a particular laboratory are without error, a good quality assurance program can minimize error and assure the highest quality data.

This presentation defines quality assurance and quality control; distinguishes between external and internal quality control; describes the elements of each, including the specimen sampling, storage, packaging, acceptance/rejection criteria, records, personnel, equipment testing, including methods and standards, proficiency testing and reporting, and discusses the interrelationship of the elements.
