Data Quality: Ensuring the Validity of Laboratory Results Using ISO/IEC 17025:2017

For those who wondered if ISO/IEC 17025 would eventually require accredited laboratories to perform proficiency testing/inter-laboratory comparisons, the answer is yes. Several additional considerations for ensuring the validity of results have been added, including expanding the focus on quality assurance.

Laboratories performing testing and/or calibration must ensure that results are valid. The requirements of clause 7.7 of ISO/IEC 17025 provide laboratories with several quality assurance/quality control mechanisms for determining the best approach for ensuring the validity of results.  Join this free webinar to learn more about the requirements in clause 7.7 with regard to ensuring the validity of results, proficiency testing, and trend analysis.
