RESUMEN
Objectives: The primary aim of this study was to determine quantitatively the extent of coverage of the Hong Kong Laboratory Accreditation Scheme (HOKLAS 015) requirements by guidance checklists (HOKLAS 016-02 and HOKLAS 021). Methods: The level of conformance requirement coverage of HOKLAS 015 by HOKLAS 016-02 and HOKLAS 021 was calculated by an evaluation checklist based on conformance requirements in HOKLAS 015. A distribution analysis of conformance requirements relating to the International Standard ISO 15189:2012 process-based quality management system model was also performed to elicit further coverage information. Results: HOKLAS 016-02 was found to provide coverage of 76% while HOKLAS 021 was found to provide coverage of 11%. HOKLAS 015 was also found to have a distribution coverage of 78% relating to the International Standard ISO 15189:2012 process-based quality management system model. Conclusion: The results of this analysis should be of value to medical laboratories wishing to maintain the internal auditability required by HOKLAS 015 by gaining an awareness of the extent of coverage provided by HOKLAS 016-02 and HOKLAS 021.
RESUMEN
In recent years, many rapid and automated instruments with highly complex testing methodologies have been introduced to our laboratories, almost all of which require the use of water. Many investigators have discussed the impact of water quality on the accuracy and reliability of clinical laboratory testing and technologies. Evaluation of water quality and specifications according to international standards and guidelines has helped laboratories to judge water quality before using the water in question as part of testing. In the past few years, dramatic introduction of different water purification technologies has shown significant improvements in laboratory testing accuracy. In this review, we delve into the intricate factors that influence water quality.
