225 Global Standardization and Quality Services of Molecular-Genetic Testing This session will present current status of the globalization of molecular-genetic testing, and associated quality issues of the testing used in daily practice. The presentation will include the global and regional efforts for standardization of molecular genetic testing and its use. Discussion will emphasize issues in quality services of the testing in situations where specimens are being transported regionally and even across borders of countries, and their routine use in care of patients with infectious, hematopoietic, neoplastic and genetic diseases. A case-based approach will demonstrate quality issues of the testing, focusing on pre-analytic processes such as design, set-up and selection of the tests, and procurement, storage, transport and preparation of specimens. Participants will recognize appropriate quality management tools and best practices in molecular-genetic testing, and eventually will be able to implement them into their daily practice.

• Participants will identify the current status of the globalization of molecular-genetic testing, and associated quality issues of the testing used in daily practice.

• Participants will recognize importance of the pre-analytic processes of molecular-genetic testing. • Participants will recognize appropriate quality management tools and the best practices in molecular-

genetic testing.

Proficiency testing �

•  The Best Practices encourage laboratories to make use of these alternative methods. Alternative methods include blind sample exchanges and review of results between laboratories, blind repeat testing, testing by different independent methods, and correlation of results to clinical and laboratory parameters. If practicable, blind sample exchanges between laboratories is the preferred approach.

「Global Standardization and Quality Services of Molecular-genetic Testing」(Summary)

1) Expanded use, penetrating into society and globalization need the standards.

2) OECD issued the guideline for quality assurance in molecular-genetic testing for clinical uses in 2007. Other international bodies such as ISO/IEC TC212, CDC and CLSI are also engaged with the standards.

3) JCCLS has been making efforts with standards. Domestic issues in Japan with respect to global standards have been raised.

4) We discussed importance of pre-analytic process in quality assurance and the JCCLS guideline for procurement of specimens.

5) Evidence-based approaches are required in drafting the guidelines. 6) Standards for pre-analytic process would be a key point not only clinical

use but also development of the system. 7) All of these activities for the global standardization of molecular-genetic

testing should lead to ensure minimum international requirements for quality assurance of a total process of the laboratory systems and practices, allowing for the appropriate diagnosis and effective control of diseases.
