BACKGROUND The measurement of cardiac troponin is crucial in the diagnosis of myocardial infarction. The performance of troponin measurement is most conveniently monitored by external quality assessment (EQA) programs. The commutability of EQA samples is often unknown and the effectiveness of EQA programs is limited. METHODS Commutability of possible EQA materials was evaluated. Commercial co...
UNLABELLED This study is performed as a part of research that examines the emission and diffusion characteristics of volatile organic compounds (VOCs) from indoor building materials. In this paper, the flow field and the emission field of VOCs from the surface of building materials in a Field and Laboratory Emission Cell (FLEC) cavity are examined by 3D Computational Fluid Dynamics (CFD) analys...

KronTag RFID tags protection meet requirements according Hybrid epoxy-urethane ...
BACKGROUND The objective of external quality assessment is to evaluate clinical acceptability of laboratory results. It is desirable to evaluate intermethod harmonization and traceability to a reference system. METHODS Conventional matrix-modified processed materials are used in most programs, because they can be produced in large quantities, can have multiple abnormal analytes in the same vi...
