Harmonization and standardization are important when disease is dened by clinical biochemistry results. Evidence based medicine is the conscious, explicit and judicious use of current best evidence in making decisions about the care of individual patients. There are very few studies proving standardisation and it's application in laboratory medicine. The objective of this study is to verify the trueness and portability of patient reports by standardization of glucose estimation using two different methods in two different analysers. Methods of estimation compared are hexokinase and GOD-POD. Instruments used are Abbott Architect c8000 and ERBA XL-640 respectively. After the analysis, the results obtained are comparable and methods are traceable and therefore can be used interchangeably for patient report evaluation. Through this experiment we conclude that standardization enables uniform interpretability, which is important in integrating health systems into modern clinical environment

In recent years, the need for the quality control, reliability, and traceability of analytical results has been strongly emphasized. The National Metrology Institute – Inmetro is involved in improving measurement capabilities to provide confidence level regarding greenhouse gases standards. The chapter describes the development of certified reference materials of carbon dioxide in atmospheric synthetic air that are used to monitor its concentration in the atmosphere. Considering the contributions from gravimetry preparation and its verification analysis by cavity ringdown spectroscopy (CRDS), the relative expanded uncertainty of the standard mixture of carbon dioxide was lower than 0.5% for the range studied from 370 to 550 μmol/mol, which is comparable to the average of 0.25% relative uncertainties presented on international standards mixtures.
