Comparative analysis of ISO 15189:2022 with earlier versions with reference to ethics.

Objectives: The International Organisation for Standardisation (ISO) 15189 standard provides the requirements for quality and competence in medical laboratories. It aims to ensure that laboratories deliver accurate and reliable results for patient care. The first version of the same was published in 2003, followed by editions in 2007, 2012 and 2022. The objective of this article is to analyze the ethical commitments and requirements assumed to achieve reliable results in laboratory medicine incorporated in the ISO standard.

Methods: We compare the concepts and changes related to ethics introduced over time in the ISO 15189 versions. We also present, a comparative study about the evolution of ethical concepts in the clinical laboratory and how these changes have been reflected in ISO 15189 standards through 2003 to 2022.

Results: After a thorough comparative analysis, we observe that the ISO 15189:2022 version has strengthened the requirements for several key concepts of Ethics such as impartiality and confidentiality, and addressed the issues of laboratory users with regards to autonomy, beneficence and justice although these terminologies are not explicitly mentioned. However, several other key words and concepts have not been addressed with adequate emphasis.

Conclusions: We recommend that several key concepts related to ethics may need to be included in the future revisions, especially those related to new and upcoming technologies being used in laboratory diagnostics and research.
