The JENSEN et al. [1] study represents a tremendous and successful effort on quality assurance and quality control as part of a large clinical study. The study or probably more likely the presentation of the study by JENSEN et al. [1] has a few limitations seen from a metrological point of view to which I want to draw attention. Traceability is the key stone of quality control of measurements a...

There is a growing requirement for an internationally accepted system of recognition of measurement capabilities and relationships within and among countries, to facilitate seamless global commerce and trade. As a result, metrologists worldwide have recently developed increased interest in the concept and definition of traceability. Classically, traceability provides a way of relating the resul...

there are significant challenges associated with qualitative and quantitative nucleic acid tests performed in diagnostic laboratories. the development of internationally available certified reference materials which can be traced to reference measurements will contribute to a better understanding of the performance characteristics of nucleic acid tests and enhance reliability and comparability ...

Nowadays the preservation of the planet is spreading into the international scene with the use of renewable energy sources such as bioethanol. The challenge is to guarantee the quality of produced bioethanol, and the electrolytic conductivity (EC) is one of the specified parameters for this purpose. However, is necessary to demonstrate the metrological traceability of the measurement results fo...

BACKGROUND In patient and population samples, generation of analytical results that are comparable and independent of the measurement system, time, and location is essential for the utility of laboratory information supplied in healthcare. Obtaining analytical measurement results with such characteristics is the aim of traceability in laboratory medicine. As awareness of the benefits of having ...

The comparability of biochemical measurement results performed by any medical laboratories could be reached only when common reference systems can be established for worldwide use. There is recognised a critical step in the reference systems to achieve traceability of values obtained using reference measurement procedures and reference materials traceable to the universally recognized and accep...

Medical measurements are present in the everyday life of people and are fundamental processes in prevention, diagnosis and treatment of disease. Therefore, a growing interest lies in the role of metrological decisions and conformity assessment, namely where measurements are in support of health. This paper focuses on the use of medical devices looking to enhance its metrological traceability, h...
