Understanding the ‘Silver Book’ — An important reference for standardised nomenclature in clinical laboratory sciences

Abstract

Clinical laboratories perform a wide menu of testing (examinations). Successful requesting, examination, and ordering in this environment requires clear standardised nomenclature. The Silver Book (SB) is an IUPAC (International Union of Pure and Applied Chemistry) publication, produced with the support of both IUPAC and the IFCC (International Federation of Clinical Chemistry and Laboratory Medicine), that makes recommendations on logical standardised nomenclature, symbols, properties, and units in many disciplines of the clinical laboratory sciences.These recommendations are founded on and in agreement with the principles and work of the International Organization for Standardization (ISO), Bureau International des Poids et Mesures (BIPM), IUPAC, and the IFCC. Practical applications described are based on those scientific principles. The SB recommendations apply to all types of examination, not only to measurement of quantities but also examination of nominal properties where no magnitude is involved. The SB is applicable not only to clinical chemistry, but to many other clinical laboratory disciplines. For examples, reports regarding haemostasis, toxicology, clinical microbiology, reproduction and fertility, clinical pharmacology, clinical allergology, clinical molecular biology, and clinical immunohaematology have been published by the IUPAC and the IFCC.Peak scientific bodies such as the IUPAC and the IFCC have important roles in the development of sound international standards for nomenclature of examinations. Such standards support safe and effective representation of patient health information, foster portability, and empower future decision support systems.
