[A proposal to convert our view from precision into accuracy in routine analysis].
Recently, measurement systems in clinical chemistry have been improved to be more precise in analysis than those in 1980s. As a result, several advances in instruments and reagents have been brought such as incorporating microprocessors into hardwares of instruments and developing ready-to-use reagents, and the precision level of measurement systems is now sufficient for routine analysis. In the near future, however, we will have to focus on the accuracy of measurement systems to obtain accurate and commutable laboratory data. We report a present status of the precision in routine analysis and our activity in data maintenance for accurate analysis by reference methods.
