Advanced and accurate measurement is a prerequisite for scientific research innovation leading towards the development of new technologies. SI traceable measurements in industry are essential global acceptance products international trading to break trade barrier. National metrology institutes (NMIs) around globe have been working on digital metrology, quantum calibration-free science technolog...

Although manufacturers are compelled by the European IVD Directive, 98/79/EC, to have traceability of the values assigned to their calibrators if suitable higher order reference materials and/or procedures are available, there is still no equivalence of results for many measurands determined in clinical laboratories. The adoption of assays with metrological traceable results will have a signifi...

Huge resources are invested in metrology and standards in the natural sciences, engineering, and across a wide range of commercial technologies. Significant positive returns of human, social, environmental, and economic value on these investments have been sustained for decades. Proven methods for calibrating test and survey instruments in linear units are readily available, as are data- and th...

At the start of the twenty-first century, a dramatic change occurred in the clinical laboratory community. Concepts from Metrology, the science of measurement, began to be formally applied to clinical laboratory field methods, resulting in a new appreciation of metrological calibrator traceability. It is a change because clinical laboratories test complex patient samples, for example, whole blo...

Clinicians request a large part of measurements biological quantities that clinical laboratories perform for diagnostic, prognostic or diseases monitoring purposes. Thus, need to provide patient’s results as reliable possible. Metrological concepts like measurement uncertainty and metrological traceability allow know the accuracy these guarantee their comparability over time space. Such is impo...
